ASPxPopupControlBase.ContentUrl Property

Specifies whether to display a web page’s navigation location in the control’s window.

Assembly: DevExpress.Web.v22.2.dll

Declaration

C#
VB.NET

[DefaultValue("")]
public string ContentUrl { get; set; }

<DefaultValue("")>
Public Property ContentUrl As String

Property Value

Type	Default	Description
String	String.Empty	The page’s navigation location.

Remarks

Use the ContentUrl property to specify the URL (relative or absolute) of a web page that should be loaded and displayed in the control’s window.

Note

The ASPxPopupControl uses the IFrame tag to show its content. When the ContentUrl property is used, the page within this IFrame doesn’t have dimensions (e.g., the browser window can be resized to all sizes, and you can’t determine the “original” page size). So, use the ASPxWebControl.Height property or the client side ASPxClientPopupControl.SetSize method to specify the popup control’s height.
The server generates the popup window’s content when you use the PerformCallback method to send a callback to the server.

Example

The example illustrates how to return values from the ASPxPopupControl’s ASPxPopupControlBase.ContentUrl page. The ContentUrl page calls the “HidePopupAndShowInfo” function, which is defined on the parent page. The function is called on the client and server sides.
