ASPxPopupControlBase.ContentUrl Property

Gets or sets the navigation location of a specific web page to be displayed within the control’s window.

Assembly: DevExpress.Web.v18.2.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	A string value that specifies the desired page’s navigation location.

Remarks

Use the ContentUrl property to specify the URL of a web page which should be loaded and displayed in the control’s window. A relative or an absolute URL can be used.

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, the popup control’s height should be specified manually via the ASPxWebControl.Height property or by using the client side ASPxClientPopupControl.SetSize method.

Note

When using ASPxDockPanel with the ContentUrl property specified, the dock panel loads its content page within an iframe element. After docking/floating ASPxDockPanel from ASPxDockZone, the dock panel’s iframe is removed from the DOM tree and reloaded. As a result, the script execution is stopped inside the iframe and the DOM API of the iframe window is no longer available. This behavior is a known issue of the IE 9 browser described in the APIs Are Not Available if iFrame Is Removed from DOM Tree MSDN article.

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.
