<Cell>.DisplayDialog (Function)

In french: <Cellule>.AfficheDialogue

Displays a Cell control in a page with a DDW effect (Dim Disabled Windows). This function is used to easily simulate a dialog box in browser code, by using a Cell control in a page.

See Communicating with the Web user for more details.

Example

// Display a Cell control containing a question
CELL_Question.DisplayDialog(cellCenter, True, 50)

Syntax

<Cell control>.DisplayDialog([<Display position> [, <Take DDW into account> [, <Rate of gray>]]])

<Cell control>: Control name

Name of the Cell control that will be displayed.

<Display position>: Optional Integer constant

Display position of cell:
cellCenter
(Default value) The Cell control is centered in the visible part of the current page.
cellBottomRight The Cell control is at the bottom right of the visible part of the current page.
cellBottomLeft The Cell control is at the bottom left of the visible part of the current page.
cellTopRight The Cell control is at the top right of the visible part of the current page.
cellTopLeft The Cell control is at the top left of the visible part of the current page.
cellPositionXY The Cell control remains at its current position.

<Take DDW into account>: Optional boolean

True (default value) to display the Cell control with a DDW effect (the page displayed behind the Cell control is grayed)
False to disable the DDW effect.

<Rate of gray>: Integer

Rate of gray (included between 0 and 100) used by the DDW.
The maximum value (100) will be used if the specified value is greater than 100.
The DDW is ignored if the specified value is less than 0. The default rate of gray is set to 18%.

Remarks

Characteristics of the Cell control

The Cell control must be overlayable ("Details" tab of the Cell control description window).
To avoid displaying unnecessary scrollbars in the browser, check the option "Automatic positioning when loading to avoid the scrollbars" ("Details" tab of the Cell control description window). This option is used to automatically position the Cell control at position (0,0) when loading the page. Then, the display position defined by <Cell>.DisplayDialog is taken into account.

Note: To run server code from a Cell control, use AJAXExecute or AJAXExecuteAsynchronous.

Special cases

<Cell>.DisplayDialog must be used to display the Cell control:
- in a "None" button. In this case, only the browser code of the button will be run.
- in a "Submit" button and activate AJAX in the code of this button. In this case, the browser code and the server code of button will be run.
The Cell control display can be hidden using <Cell>.CloseDialog.
The browsers do not refresh the display in the middle of a JavaScript code: <Cell>.DisplayDialog and <Cell>.CloseDialog must be used in different events/processes. If these functions are used in the same event/process, the Cell control is not displayed.
It is not possible to display two different Cell controls at the same time using <Cell>.DisplayDialog.
