FILEUPLOAD/FILEUPLOAD2

The file upload controls simplify the process of uploading files from the client to the server. Two types are available:

Both types have the program binding, i.e. you can switch between the two types without touching your code.

The following topics are covered below:


FILEUPLOAD

The FILEUPLOAD control simplifies the process of uploading files from the client to the server. Look at the following example:

graphics/image101.png

The control - from the look-and-feel perspective - is a button with some special reaction. When you choose the button, the following dialog appears:

graphics/image102.png

You can either enter a file name or you can invoke the file selection dialog by choosing the button to the right of the field (which appears in the language of the browser).

graphics/image103.png

After choosing the Upload button, the first screen looks as follows:

graphics/image104.png

FILEUPLOAD2

With the FILEUPLOAD2 control, you embed the file upload form into your page.

Upload

You can either enter a file name or you can invoke the file selection dialog by choosing the button to the right of the field (which appears in the language of the browser).

After choosing the file, the screen looks as follows:

FILEUPLOAD Properties

Basic
name

Text that is displayed inside the control. Please do not specify the name when using the multi language management - but specify a "textid" instead.

Sometimes obligatory  
textid

Multi language dependent text that is displayed inside the control. The "textid" is translated into a corresponding string at runtime.

Do not specify a "name" inside the control if specifying a "textid".

Sometimes obligatory  
cfileprop

Name of the adapter parameter in which the client file name is passed at upload time.

Obligatory  
sfileprop

Name of the adapter parameter in which at upload time the name of the target file is written, which is a copy of the client file in the server file system. Note that this file name is not the same as the client file name.

Obligatory  
method

Name of the event that is sent to the adapter when a file is uploaded. The file data is available on the server at the point of time this method is called.

Obligatory  
comment

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

Optional  
Appearance
image

URL of image that is displayed inside the control. 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

gif

jpg

jpeg

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

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 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 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.

visibleprop

Name of the adapter parameter that provides the information if this control is displayed or not. As consequence you can control the visibility of the control dynamically.

Optional  
invisiblemode

This property has three possible values:

(1) "invisible": the button is not visible without occupying any space.

(2) "disabled": the button is deactivated: it is "grayed" and does not show any roll over effects any more.

(3)"cleared": the button is not visible but it still occupies space.

Optional

invisible

cleared

buttonstyle

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  
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.

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.

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

(2) "disabled": the control is deactivated: it is "grayed" and does not show any roll over effects any more.
