Examples

The following code example demonstrates declarative and programmatic use of the Description 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 Description 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>

<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 how to access the property programmatically to display its value in a label.

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 +
    "<br />" +
    "<em>TitleIconImageUrl: </em>" + listPart.TitleIconImageUrl +
    "<br />" +
    "<em>ChildControl ID: </em>" + listPart.ChildControl.ID +
    "<br />" +
    "<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;
}

Remarks

The Description property value is typically used as a descriptive string for a control in catalogs that provide lists of server controls, and as a ToolTip in a control's title bar. The content of the property appears in a ToolTip when a user positions the mouse pointer over the title text in a control's title bar.

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.
