Protected ReadOnly Property Zone As WebPartZoneBase

Property Value

A reference to a WebPartZoneBase that is associated with the WebPartChrome.

Examples

This code example demonstrates use of the Zone property. For the full code required to run the example, see the Example section of the WebPartChrome class overview topic.

The following code example uses the Zone property to determine whether the zone currently associated with the WebPartChrome object is a zone of type MyZone. If so, the control's contents are rendered. This code would prevent the custom WebPartChrome object from working with any other zone besides the one designed to create an instance of it.

protected override void RenderPartContents(HtmlTextWriter writer, 
  WebPart part)
{

    if (part == this.WebPartManager.SelectedWebPart)
      HttpContext.Current.Response.Write("<span>Not rendered</span>");
    else
      if(this.Zone.GetType() == typeof(MyZone))
        part.RenderControl(writer);
}

Protected Overrides Sub RenderPartContents _
  (ByVal writer As HtmlTextWriter, ByVal part As WebPart)

  If part Is Me.WebPartManager.SelectedWebPart Then
    HttpContext.Current.Response.Write("<span>Not rendered</span>")
  Else
    If (Me.Zone.GetType() Is GetType(MyZone)) Then
      part.RenderControl(writer)
    End If
  End If

End Sub

If you load the Web page in a browser, the content of each control is rendered normally. You can switch the page into design mode by selecting Design in the Display Mode drop-down list control. If you drag one of the controls into the empty zone labeled WebPartZone2, its contents are rendered differently, because the custom WebPartChrome object is not being used for the rendering. This is the same effect that you would achieve if you tried to use the custom WebPartChrome class with any other zone besides the MyZone class, because of the preceding source code.

Remarks

The Zone property provides a reference to the WebPartZoneBase zone that contains the controls for which the WebPartChrome object provides rendering.
