# TOGGLE

The TOGGLE control is used to display and to edit a selection status. In principle, it acts similar to a CHECKBOX control, but it

- allows to define different icon images for the "true" and "false" representations;

- allows being informed when the user presses the CTRL or SHIFT key when clicking the icon. With this information, you can react on a combination of SHIFT and click in a different way than to a normal click or a combination of CTRL and click. This is especially useful inside grid processing when you want to allow the user to do mass selections.

The following topics are covered below:

- Properties

## Properties

Basic
valueprop | Name of the adapter parameter that represents the value of the control. | Obligatory |
trueimage | Image URL that is shown if the corresponding property value is "true". | Obligatory | gif jpg jpeg
falseimage | Image URL that is shown if the corresponding property value is "true". | Obligatory | gif jpg jpeg
comment | Comment without any effect on rendering and behaviour. The comment is shown in the layout editor's tree view. | Optional |
Appearance
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. | Optional | 100 120 140 160 180 200 50% 100%
height | Height of the control. There are three possibilities to define the height: (A) You do not define a height at all. As consequence the control will be rendered with its default height. If the control is a container control (containing) other controls then the height of the control will follow the height of its content. (B) Pixel sizing: just input a number value (e.g. "20"). (C) Percentage sizing: input a percentage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a height this control can reference. If you specify this control to have a height of 50% then the parent element (e.g. an ITR-row) may itself define a height of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect. | Optional |
partialimage | Image URL that is shown if the corresponding property value is "null". | Optional |
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. | Optional | 1 2 3 4 5 50 int-value
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. | Optional | 1 2 3 4 5 50 int-value
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 | -1 0 1 2 5 10 32767
backgroundclass | CSS style class definition that is directly passed into this control. The style class can be either one which is part of the "normal" CIS style sheet files (i.e. the ones that you maintain with the style sheet editor) - or it can be one of an other style sheet file that you may reference via the ADDSTYLESHEET property of the PAGE tag. | Optional |
Binding
valueprop | (already explained above) |  |
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". In responsive controls additionally the values "WARNING" and "SUCCESS" are supported. The value "INVISIBLE" is only supported if the control does not support an INVISIBLEPROP. Use DISPLAYPROP or VISIBLEPROP if available to render the control displayonly/invisible/cleared. | Optional |
shiftmethod | Name of the event that is sent to the adapter when the user clicks on the toggle control and presses the Shift-key the same time. | Optional |
controlmethod | Name of the event that is sent to the adapter when the user clicks on the toggle control and presses the Ctrl-key the same time. | Optional |
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 representation 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 |
Online Help
title | Text that is shown as tooltip for the control. Either specify the text "hard" by using this TITLE property - or use the TITLETEXTID in order to define a language dependent literal. | Optional |
titletextid | Text ID that is passed to the multi lanaguage management - representing the tooltip text that is used for the control. | 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: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 |
