  (using RadRotator 2.5)
  
  In a nutshell, how can the RadRotator to "freeze" when an item is clicked? I have autopostback="true" (so I can capture the ItemClicked event on the server-side), and every time I click on the item, the RadRotator returns to the first item in the list (of items).  I'm setting the datasource for the RadRotator only if the page isn't a postback ( if (!Page.IsPostBack) ).
  
  <radR:RadRotator ID="RadRotator1" runat="server"
                          AutoPostBack="True"                     OnItemClicked="RadRotator1_ItemClicked"                         
                          AutoAdvance="false"                         
                          FramesToShow="2"
                          Width="400"
                          Height="100" 
                          FrameTimeout="0"
                          TransitionType="Scroll"
                          ScrollDirection="left"
                          ScrollSpeed="2"
                          UseSmoothScroll="True">
  
  Thanks,

  In the ItemClicked postback event handler, you can get the index of the frame using e.Item.ItemIndex, for example:
  
  protected void RadRotator1_ItemClicked(object o, Telerik.WebControls.RadRotatorClickEventArgs e)
      {
          int frameIndex = e.Item.ItemIndex;
      }

  Sure, now I've got the index captured -- but how do I set the RadRotator to a specific frame?
  
  Thanks,

  Hello Mark,
  
  Unfortunately, you can not set the rotator to a specific frame. We will try to take care of this limitation in the next major version of the control.

  Not built in the product, but you can still do it. It will require additional code though. You need to reorder your datasource (e.g. SqlDataSource, DataTable, ArrayList, etc) to start with the frame you want and then rebind the rotator in the ItemClicked event handler.

  Has this feature been added yet. I would like to change the index of the radrotator to a specific index without rebinding to a datasource when i hover over a specific button below the rotator.

  Hello Fergus,
  
  In RadRotator for ASP.NET AJAX we have the InitialItemIndex property which specifies the index of the item, which will be shown first when the rotator loads.
  
      * When set to 0 (default) - positions initial item to be visible in the rotator.
      * When set to -1 - positions the initial item just outside of the rotator viewport.
  
  Any other positive value - the rotator starts with that particular item in the viewport.

  Thanks for reply. So then it is not possible for it to be changed from the client side with javascript?

  Hello Fergus,
  
  Currently this is not possible, but I logged this as a feature request in our database and we will try to implement it for one of the following updates.
  
  Your points were updated.

  Just curious if this was ever added to the Ajax rotator. If so how do you change the rotator image by passing a index value.. Say 2? Also how would you get the index count of rotator to make sure there are 3 items and an error is not thrown.
  
  Thanks!

  Hi Mike,
  
  This feature already exists in RadRotator for ASP.NET AJAX and you can explore it in action in this online demo.
