    Hello Christian,

    You can set  each item in the RadRotator as the TargetControl for the.RadContextMenu. Here is the sample code for achieving the same.

    aspx:
    <telerik:RadRotator ID="RadRotator1" runat="server" RotatorType="Buttons" Height="100px"
                Width="200px" OnClientLoad="OnClientLoad" OnItemDataBound="RadRotator1_ItemDataBound">
          <Items>
               <telerik:RadRotatorItem>
               <ItemTemplate>
                   <img src="../Images/ANATR.jpg" alt="yellow flowers" />
               </ItemTemplate>
               </telerik:RadRotatorItem>
               <telerik:RadRotatorItem>
                <ItemTemplate>
                    <img src="../Images/ANATR.jpg" alt="yellow flowers" />
                </ItemTemplate>
               </telerik:RadRotatorItem>
               <telerik:RadRotatorItem>
                 <ItemTemplate>
                  <img src="../Images/ANATR.jpg" alt="yellow flowers" />
                  </ItemTemplate>
              </telerik:RadRotatorItem>
              <telerik:RadRotatorItem>
                  <ItemTemplate>
                   <img src="../Images/ANATR.jpg" alt="yellow flowers" />
           </ItemTemplate>
            </telerik:RadRotatorItem>
          </Items>
    </telerik:RadRotator>
    <telerik:RadContextMenu ID="RadContextMenu1" runat="server">
       <Items>
           <telerik:RadMenuItem Text="Preview">
           </telerik:RadMenuItem>
       </Items>
    </telerik:RadContextMenu>

    C#:
    protected void Page_Load(object sender, EventArgs e)
      {
          foreach (RadRotatorItem item in RadRotator1.Items)
          {
              ContextMenuControlTarget target = new ContextMenuControlTarget();
              target.ControlID = item.ClientID;
              RadContextMenu1.Targets.Add(target);
          }
      }

    Thanks,
    Shinu.

    Hey Shinu,

    that's a good idea. But if I right click on a RadRotatorItem nothing happens. So something must be implement on client side (javascript) or?

    Thanks for your support on this issue!

    Kind regards
    Christian

    Hello Christian,
    You need to attach events to handle the RadContextMenuItem click. and handle the event from there.
    aspx:
    <telerik:RadContextMenu ID="RadContextMenu1" runat="server"
              OnClientItemClicking="OnClientItemClicking"
              onitemclick="RadContextMenu1_ItemClick">
               . . . . . . . . . . . . .

    Javascript:
    function OnClientItemClicking(sender, args)
      {
     //your code here
      }

    Here you can find more on handling the clicked item form client side and server side.
    OnClientItemClicking
    ItemClick

    Thanks,
    Shinu.

    Dear Shinu,

    thanks again!

    We missunderstood us on this point. I mean something different. What must I implemented, to archive that the RadContetMenu is shown if I right click on a RadRoatatorItem. But I noticed that this behaviour is archive by adding targets to the RadContextMenu. So far its great.

    But unfortunatly if a ajax postback is occured the RadConxtstMenu isn't shown again when I right click on another RadRotatorItem after the ajax postback. If I processed a full postback the RadContextMenu is back again.

    I try to maintain the RadContextMenu by adding the targets on every kind of postback again, but it doesn't helps!

    Whats the problem here?

    Thanks for help, again! :)

    Greetings,
    Christian

    Dear Shinu,

    I found my problem. I forgot to maintain the ajax settings on the RadAjaxManager. So everthing works fine for me!

    Thanks a lot and enjoy your weekend!

    Greetings,
    Christian
