Gets or sets the URL to an image that represents a WebPart control in a catalog of controls.
Assembly: System.Web (in System.Web.dll)
Web Parts applications often provide a catalog (or list) of controls that users can add to a page. Theproperty on a control contains the URL to an image that represents the control when it appears in a catalog.
The following code example demonstrates declarative and programmatic use of the IWebPart class overview.property. The complete source code for the example is found in the Example section of the
The first part of the code example shows how the user control implements theproperty.
The second part of the code example demonstrates the method in the user control that programmatically sets the value of theproperty when a user selects the appropriate property name from the radio buttons on the page, sets a new value in the text box, and then clicks the Update button.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
The third part of the code example shows how the user control that implements the IWebPart interface is referenced in a WebPartZone control, and how the property is set declaratively on the control. Note that because there is no catalog of Web Parts controls provided with this example, you cannot see the actual effect of setting this property.
