Assembly:  System.Web (in System.Web.dll)

public override string CatalogIconImageUrl { get; set; }

Property Value

Type: System.String

A string that represents the URL to an image used to represent the control in a catalog. The default value is an empty string ("").

Web Parts applications often provide a catalog (or list) of controls that users can add to a page. The CatalogIconImageUrl property on a control contains the URL to an image that represents the control when it appears in a catalog. This property overrides the base property so that you can access the property on the child control as if it were a true WebPart control.

You can set values for the property on your control in the declarative markup of a Web page, as well as programmatically. To provide a default value for the property whenever the control is used, you can implement the IWebPart interface.

The following code example demonstrates declarative and programmatic use of the CatalogIconImageUrl property. The complete source code for the example is found in the Example section of the GenericWebPart overview topic.

The first part of the code example shows how the CatalogIconImageUrl property is set declaratively on a server control within a WebPartZone control.

<asp:WebPartZone ID="WebPartZone1" runat="server">
  <ZoneTemplate>
    <asp:Calendar ID="Calendar1" runat="server"
      Title="My Calendar"
      Description="A calendar used as a GenericWebPart control."
      CatalogIconImageUrl="MyCatalogIcon.gif"
      TitleIconimageUrl ="MyTitleIcon.gif"
      TitleUrl="MyInfoUrl.htm" 
      Width="250"/>
  </ZoneTemplate>
</asp:WebPartZone>

The second part of the code example demonstrates the method that programmatically accesses the value of the property when a user clicks the Display All Property Values button.

protected void Button1_Click(object sender, EventArgs e)
{

  Label2.Text =
    @"<h3>Calendar GenericWebPart Properties</h3>" +
    "<em>Title: </em>" + calendarPart.Title +
    "<br />" +
    "<em>CatalogIconImageUrl:  </em>" + calendarPart.CatalogIconImageUrl +
    "<br />" +
    "<em>TitleUrl: </em>" + calendarPart.TitleUrl +
    "<br />" +
    "<em>Decription: </em>" + calendarPart.Description +
    "<br />" +
    "<em>TitleIconImageUrl: </em>" + calendarPart.TitleIconImageUrl +
    "<br />" +
    "<em>ChildControl ID: </em>" + calendarPart.ChildControl.ID +
    "<br />" +
    "<em>ChildControl Type: </em>" + calendarPart.ChildControl.GetType().Name +
    "<br />" +
    "<em>GenericWebPart ID: </em>" + calendarPart.ID +
    "<br />" +
    "<em>GenericWebPart Type: </em>" + calendarPart.GetType().Name +
    "<br />" +
    "<em>GenericWebPart Parent ID: </em>" + calendarPart.Parent.ID;

  Label3.Text =
    @"<h3>BulletedList GenericWebPart Properties</h3>" +
    "<em>Title: </em>" + listPart.Title +
    "<br />" +
    "<em>CatalogIconImageUrl:  </em>" + listPart.CatalogIconImageUrl +
    "<br />" +
    "<em>TitleUrl: </em>" + listPart.TitleUrl +
    "<br />" +
    "<em>Decription: </em>" + listPart.Description +

    "<em>ChildControl Type: </em>" + listPart.ChildControl.GetType().Name +
    "<br />" +
    "<em>GenericWebPart ID: </em>" + listPart.ID +
    "<br />" +
    "<em>GenericWebPart Type: </em>" + listPart.GetType().Name +
    "<br />" +
    "<em>GenericWebPart Parent ID: </em>" + listPart.Parent.ID;
}
