FIELD

The FIELD control is used for entering data. It provides the following features:

  • Normal input/output of text.

  • Password input.

  • Autocomplete (see also the AUTOCOMPLETE control).

  • Dynamic control if input is allowed.

  • Dynamic highlighting of field in case of errors.

  • Flush the input directly to the server when leaving the field.

  • Raise an event on pressing F4 or F7 or on click - useful for value help pop-up dialogs

  • Adapt the output to a data type (e.g. transfer "YYYYMMDD" to a visible date field)

The following topics are covered below:

Properties

Basic
valueprop

Name of the adapter parameter that provides the content of the control.

Obligatory  
width

Width of the control.

There are three possibilities to define the width:

(A) You do not define a width at all. In this case the width of the control will either be a default width or - in case of container controls - it will follow the width that is occupied by its content.

(B) Pixel sizing: just input a number value (e.g. "100").

(C) Percentage sizing: input a percantage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a width this control can reference. If you specify this control to have a width of 50% then the parent element (e.g. an ITR-row) may itself define a width of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect.

comment

Comment without any effect on rendering and behaviour. The comment is shown in the layout editor's tree view.

Optional  
Appearance
width (already explained above)    
length

Width of FIELD in amount of characters. WIDTH and LENGTH should not be used together. Note that the actual size of the control depends on the font definition if using the LENGTH property.

Optional

15

20

int-value

maxlength

Maximum number of characters that a user may enter. This property is not depending on the LENGTH property - please do not get confused by the similar naming. MAXLENGTH has nothing to do with the optical sizing of the control but only with the number of characters you may input.

Optional

5

10

15

20

int-value

autotab

If set to true, an automatic tab is executed for fields with a specified MAXLENGTH when the maxlength value is reached. For fields without a MAXLENGTH specified it has no effect. Default is true.

Optional

true

false

textalign

Alignment of text inside the control.

Optional

left

center

right

password

If set to "true", each entered character is displayed as a '*'.

Optional

true

false

displayonly

If set to true, the FIELD will not be accessible for input. It is just used as an output field.

Optional

true

false

direction

Presets the default(BiDi) direction of the control. Use black string in order to have the default value.

Optional

rtl

ltr

uppercase

If "true" then all input is automatically transferred to upper case characters.

Optional

true

false

align

Horizontal alignment of control in its column.

Each control is "packaged" into a column. The column itself is part of a row (e.g. ITR or TR). Sometimes the size of the column is bigger than the size of the control itself. In this case the "align" property specifies the position of the control inside the column. In most cases you do not require the align control to be explicitly defined because the size of the column around the controls exactly is sized in the same way as the contained control.

If you want to directly control the alignment of text: in most text based controls there is an explicit property "textalign" in which you align the control's contained text.

Optional

left

center

right

valign

Vertical alignment of control in its column.

Each control is "packaged" into a column. The column itself is part of a row (e.g. ITR or TR). Sometimtes the size of the column is bigger than the size of the control. In this case the "align" property specify the position of the control inside the column.

Optional

top

middle

bottom

colspan

Column spanning of control.

If you use TR table rows then you may sometimes want to control the number of columns your control occupies. By default it is "1" - but you may want to define the control to span over more than one columns.

The property only makes sense in table rows that are snychronized within one container (i.e. TR, STR table rows). It does not make sense in ITR rows, because these rows are explicitly not synched.

rowspan

Row spanning of control.

If you use TR table rows then you may sometimes want to control the number of rows your control occupies. By default it is "1" - but you may want to define the control to span over more than one columns.

The property only makes sense in table rows that are snychronized within one container (i.e. TR, STR table rows). It does not make sense in ITR rows, because these rows are explicitly not synched.

int-value

fieldstyle

CSS style definition that is directly passed into this control.

With the style you can individually influence the rendering of the control. You can specify any style sheet expressions. Examples are:

border: 1px solid #FF0000

background-color: #808080

You can combine expressions by appending and separating them with a semicolon.

Sometimes it is useful to have a look into the generated HTML code in order to know where direct style definitions are applied. Press right mouse-button in your browser and select the "View source" or "View frame's source" function.

Optional

background-color: #FF0000

color: #0000FF

font-weight: bold

stylevariant

Some controls offer the possibility to define style variants. By this style variant you can address different styles inside your style sheet definition file (.css). If not defined "normal" styles are chosen, if defined (e.g. "VAR1") then other style definitions (xxxVAR1xxx) are chosen.

Purpose: you can set up style variants in the style sheet defintion and use them multiple times by addressing them via the "stylevariant" property. CIS currently offerst two variants "VAR1" and "VAR2" but does not predefine any semantics behind - this is up to you!

Optional

VAR1

VAR2

noborder

Boolean value defining if the control has a border. Default is "false".

Optional

true

false

transparentbackground

Boolean value defining if the control is rendered with a transparent background. Default is "false".

Optional

true

false

bgcolorprop

Name of the adapter parameter that provides the background color of the control.

Optional  
fgcolorprop

Name of the adapter parameter that passes back a color value (e.g. "#FF0000" for red color). The color value is used as text color in the control. - The background color is automatically chosen dependent from the text color: for light text colors the background color is black, for dark text colors the color is default. Use BGCOLORPROP to choose both - text and background color.

Optional  
invisiblemode

If the visibility of the control is determined dynamically by an adapter property then there are two rendering modes if the visibility is "false":

(1) "invisible": the control is not visible.

(2)"cleared": the control is not visible but it still occupies space.

Optional

invisible

cleared

tabindex

Index that defines the tab order of the control. Controls are selected in increasing index order and in source order to resolve duplicates.

Optional

Binding
valueprop (already explained above)    
alwaysflush

If set to TRUE then a specified server flushmethod is also called in case the value has not changed. The default is FALSE, meaning that a server flushmethod is only called for a changed value.

Optional

true

false

flush

Flushing behaviour of the input control.

By default an input into the control is registered within the browser client - and communicated to the server adapter object when a user e.g. presses a button. By using the FLUSH property you can change this behaviour.

Setting FLUSH to "server" means that directly after changing the input a synchronization with the server adapter is triggered. As consequence you directly can react inside your adapter logic onto the change of the corresponding value. - Please be aware of that during the synchronization always all changed properties - also the ones that were changed before - are transferred to the adapter object, not only the one that triggered the synchonization.

Setting FLUSH to "screen" means that the changed value is populated inside the page. You use this option if you have redundant usage of the same property inside one page and if you want to pass one changed value to all its representaion directly after changing the value.

Optional

screen

server

flushmethod

When the data synchronization of the control is set to FLUSH="server" then you can specify an explicit event to be sent when the user updates the content of the control. By doing so you can distinguish on the server side from which control the flush of data was triggered.

Optional  
flushindexprop

Name of a changeindexprop property of another control. On flush='screen" the value of the specified property is automatically increased so that the controls is automatically refreshed. This property is ignored for flush="server"

Optional  
contextmenu

If set to TRUE for a field myfield, method/event reactOnContextMenuMyfield will be called/triggered on right mouse click. In this method/event you can set a contextmenu correspondingly. Please use the attribute CONTEXTMENUMETHOD in case you would like to use a different method/eventname. In case a valid value is specified for the CONTEXTMENUMETHOD attribute, the value for the CONTEXTMENU attribute is ignored. Default value is FALSE.

Optional

true

false

contextmenumethod

Name of the event that is sent to the adapter when the user presses the right mouse button in an empty area.

Optional  
onclickmethod

Name of the event that is sent to the adapter when the user clicks.

Optional  
ondblclickmethod

Name of the event that is sent to the adapter when the user double clicks.

Optional  
displayprop

Name of the adapter parameter that dynamically passes information whether the field is displayonly("true") or not ("false"). Notice that in the Natural code the type for the field is alphanumeric.

Optional  
statusprop

Name of the adapter parameter that dynamically passes information how the control should be rendered and how it should act. Valid parameter values at runtime: "INVISIBLE", "FOCUS", "FOCUS_NO_SELECT", "ERROR", "ERROR_NO_FOCUS". Use DISPLAYPROP to dynamically define whether the field is displayonly.

Optional  
valuetextprop

Name of the adapter parameter that provides a "human understandable" description for the value: in some cases you enter an id into a FIELD but want to display the id and a description to the user. At runtime, the values provided by the VALUEPROP- and the VALUETEXTPROP-property are combined into one text (string) that is returned into the FIELD.

Optional  
textidmode

If using property "valuetextprop" then a field knows an id and a text for a certain value. There are three types of display: either both are shown together, separated by an "-" (e.g. "id - text"). Or only text is shown or only the id is shown. If not defined at all then the system's default text id-mode will be chosen. The default mode can be defined as part of the CIS session context.

Optional

2

titleprop

Name of the adapter parameter that dynamically defines the title of the control. The title is displayed as tool tip when ther user moves the mouse onto the control.

Optional  
bgcolorprop (already explained above)    
fgcolorprop (already explained above)    
autocallpopupmethod

Name of the adapter parameter that controls that the field's value help event is sent to the adapter with a certain offset (milliseconds) after last key down event.

Optional

true

false

lengthprop

Name of the adapter parameter that dynamically provides the width of the FIELD in amount of characters.

Optional  
maxlengthprop

Name of the adapter parameter that provides the maximum number of characters that a user may enter. Consider to use MAXLENGTH to define this number in a static way.

Optional  
Validation
datatype

By default, the FIELD control is managing its content as string. By explicitly setting a datatype you can define that the control...

...will check the user input if it reflects the datatype. E.g. if the user inputs "abc" into a field with datatype "int" then a corresponding error message will popup when the user leaves the field.

...will format the data coming from the server or coming form the user input: if the field has datatype "date" and the user inputs "010304" then the input will be translated into "01.03.2004" (or other representation, dependent on date format settings).

In addition valeu popups are offered for the user automatically for some datatypes: e.g. when specifying datatype "date" the automatically the field provides a calendar input popup.

Please note: the datatype "float" is named a bit misleading - it represents any decimal format number. The server side representation may be a float value, but also can be a double or a BigDecimal property.

Optional

validationprop

Name of the adapter parameter that provides a regular expression for the validation of the field. Works the same way as VALIDATION but in a dynamic way.

Optional  
validationuserhint

If a client side validation fails due to wrong user input then an error popup is opened. If you define a hint inside this property then the hint is output to the user in order to tell in which way to input the value. The hint is not language dependent.

Optional  
validationuserhintprop

If using validation expressions (either property "validation" or "validationprop") then a popup comes up if the user inputs wrong values into a field. Inside this popup a certain text may be added in order to explain to the user what he/she did not correctly input. This text can be either statically defined or dynamically - by using this property.

Optional

Valuehelp
popupmethod

Name of the event that is sent to the adapter when the user requests value help by pressing F4 or F7 or by clicking into the FIELD with the right mouse button. When using the popupmethod together with the NJX:EVENTDATA control in a grid, then the event name must have the griddataprop name as prefix. Example: mygrid.mypopupmethod. If the POPUPMETHOD is defined, a small icon is shown inside the field to indicate to the user that there is some value help available.

Optional

openIdValueCombo

openIdValueHelp

openIdValueComboOrPopup

popupinputonly

Boolean property that control if a field with POPUPMETHOD defined is still usable for keyboard input. If "false" (= default) then the user can input a value either directly via keyboard or by using the popupmethod's help. If set to "true" then no keyboard input is possible - but only selection from the popup-method's help.

Optional

true

false

popupprop

Name of the adapter parameter that provides the information whether a POPUPMETHOD is available or not. This feature is used in scenarios in which a FIELD offers e.g. value help or not, depending on business logic inside the adapter.

Optional  
popuponalt40

Value help in a field is triggered either by clicking with the mouse or by pressing a certain key inside the field. The "traditional" keys are "cusrsor-down", "F7" or "F4". Sometimes you do not want to mix other "cursor-down" behaviour (e.g. scrolling in lists) with the value help behaviour. In this case switch this property to "true" - and the value help will only come up anymore when "alt-cursor-down" is pressed.

popupicon

URL of image that is displayed inside the right corner of the field to indicate to the user that there is some value help available.. Any image type (.gif, .jpg, ...) that your browser does understand is valid.

Use the following options to specify the URL:

(A) Define the URL relative to your page. Your page is generated directly into your project's folder. Specifiying "images/xyz.gif" will point into a directory parallel to your page. Specifying "../HTMLBasedGUI/images/new.gif" will point to an image of a neighbour project.

(B) Define a complete URL, like "http://www.softwareag.com/images/logo.gif".

Optional

Optional

true

false

onlinehelp
helpid

Help id that is passed to the online help management in case the user presses F1 on the control.

Optional  
title

Text that is shown as tooltip for the control.

Optional  
autocompleteresultsref

Sets a reference to an additional control to display the total number of results. Use this when the number of matching items can be very high and you limited the number of displayed items in the dropdown for performance reasons. As value set the valueprop of the control in which you would like to display the total number.

Optional  
autocompletewithdropdown

If set to "TRUE" a dropdown button/icon will be appended to the field. When it is clicked, all items are shown.

Optional

Natural
njx:natname

If a Natural variable with a name not valid for Application Designer (for instance #FIELD1) shall be bound to the control, a different name (for instance HFIELD1) can be bound instead. If the original name (in this case #FIELD1) is then specified in this attribute, the original name is generated into the parameter data area of the Natural adapter and a mapping between the two names is generated into the PROCESS PAGE statement of the Natural adapter. This mapping must not break a once defined group structure. If for instance a grid control that is bound to a name of GRID1 contains fields that are bound to FIELD1 and FIELD2 respectively, the corresponding njx:natname values may be #GRID1.#FIELD1 and #GRID1.#FIELD2, but not #GRID1.#FIELD1 and #MYGRID1.#FIELD2.

Optional  
njx:natsysvar

If the control shall be bound to a Natural system variable, this attribute specifies the name of the system variable.

Optional  
njx:natsysio

If the control shall be bound to a Natural system variable with the attribute njx:natsysvar, this attribute indicates if the system variable is modifiable. The default is false.

Optional  
njx:natstringtype

If the control shall be bound to a Natural system variable of string format with the attribute njx:natsysvar, this attribute indicates the format of the string, A (code page) or U (Unicode). The default is A.

Optional  
njx:natcv

Name of a Natural control variable that shall be assigned to the control.

Optional  
njx:natcomment

The value of this attribute is generated as comment line into the parameter data area of the Natural adapter, before the field name. The Map Converter, for instance, uses this attributes to indicate for a generated statusprop variable to which field the statusprop belongs.

Optional  
Miscellaneous
testtoolid

Use this attribute to assign a fixed control identifier that can be later on used within your test tool in order to do the object identification

Optional
