ASPxClientPopupControlBase.AfterResizing Event

Occurs on the client side when window resizing completes.


AfterResizing: ASPxClientEvent<ASPxClientPopupWindowEventHandler<ASPxClientPopupControlBase>>

Event Data

The AfterResizing event's data class is ASPxClientPopupWindowEventArgs. The following properties provide information specific to this event:

Property Description
window Gets the popup window object related to the event.


The ASPxClientPopupControlBase.BeforeResizing and AfterResizing events allow a window's content to be programmatically hidden/minimized and restored when the window is resized by an end-user.

These events are useful, allowing a window to be resized per end-user requirements. For instance, typically, an end-user can't resize a window to make it smaller than its content (such as an image). Now, to allow such window resizing, you can programmatically minimize or hide the window's content, by handling the ASPxClientPopupControlBase.BeforeResizing event, and restore/update the content's size according to the new size of the window within the AfterResizing event handler.


At present, ASPxPopupControl does not have the built-in capability to resize nested controls when it's resizing. This example illustrates how to automatically resize controls places inside the popup.

To accomplish this task, execute the following steps:

  1. Set the ScrollBars property to "Auto". This option will allow the popup control to evaluate the content width and height.

  2. Handle the AfterResizing event. In this event handler, call the AdjustControl method for a desired control to force it to reevaluate its size.

  3. Place the control into the <div style="height: 100%; width: 100%; overflow: hidden"> element. This element is necessary to overcome scrollbars that can be shown when ScrollBars="Auto" is set.
