    I want to have a toggle button decide which rotator items get sent into the control...

    Now looking at the clientside functions I think I could do it manually by adding items, but since it's already got the service functionality built in I'd love to just leverage that...

    Hi Steve,

    As I have already answered your support ticket, the only solution is to use a Session variable in order to pass additional values to the WebService's method. This solution, however, will not work if the RadRotator control is declared in the ItemTemplate of a databound control.

    Hmmm, I don't seem to have any tickets that mention this :)

    Session won't work as the buttons are clientside and the Rotator is set to WebService binding.  There are other controls like the scheduler which allow me to PASS values into the service to use, but I dont see anything in the rotator that will let me attach clientside parameters to consume with the service.

    Therefore the only thing I can think of is to use a RadXmlHttpPanel, then manually populate the rotator (which is not only a pain, but adds an extra control when I'm trying to keep the page lean).

    Hi Steve,

    "Hmmm, I don't seem to have any tickets that mention this :)"
    I apologize, this was my mistake :).


    In reference to your question:
    Unfortunately, the requested client-side functionality does not exist and for the time being you can change the service only on the server. to do that, I recommend you to wrap the control and the buttons in an RadAjaxPanel (or use a RadAjaxManager in order to implement your scenario) and then change the RadRotator's WebService settings in the Button's Click server-side event. In this case you can assign a Session value and then use that value in the WebService method.

    I hope this helps.

    All the best,

    Hmmm I need the type of clientside performance that msajax just cannot provide :/

    Okay, I guess I'll go about manually building the rotator items after a callback.  OR (what about this)...on click of the button add in a dummy clientside rotator item which will instruct the service to do X when it sees it in the collection.  Then perhaps on the serverside REMOVE that temporary item.

    Most of the telerik control which do webservice binding provide the ability to pass values back to the services...if it wont get Q3 2010, can I get it added to PITS please?

    Hello Steve,

    Yes the change is included in the latest internal build. You can pass parameters to the server using this approach:
    • Attach a handler to the OnClientItemsRequesting
    • Implement the handler as shown bellow:
      <script type="text/javascript">
          function OnClientItemsRequesting(oRotator, args)
          {
              args.set_argument("a string value");
          }
      </script>
    • Then get the value in the web service as shown bellow:
      [WebMethod]
      public RadRotatorItemData[] GetRotatorData(int itemIndex, string argument)
      {
          if (itemIndex >= maxItemsCount) return null;
          List<RadRotatorItemData> result = new List<RadRotatorItemData>();
       
          for (int i = itemIndex; i < itemIndex + itemCount; i++)
          {
              RadRotatorItemData item = new RadRotatorItemData();
              item.Html = this.GetRadioButtonList();
              result.Add(item);
          }
       
          return result.ToArray();
      }

      Please note that the name of the argument is important
