The RadDock control can be dragged using Grips or TitleBar depending on the DockHandle property. You can also do change the handle on the client via the set_handle method:

  • Set the content of the RadDock object:
    <telerik:RadDock ID="RadDock4" runat="server">
        <ContentTemplate>
            You can drag this object using the image below: <img id="HandleImage4" src="../Skinning/Thumbnails/Blue.gif" alt="Image" />
        </ContentTemplate>
    </telerik:RadDock>
  • Handle the OnClientInitialize event of the RadDock—in the handler function get reference to your RadDock object and also the object within RadDock's template that you would like to set as a dock handle. Then, use set_handle method to set the RadDock's new handle element
    function OnClientInitialize(dock, args) {
        var dragHandle = document.getElementById("HandleImage4");
        dock.set_handle(dragHandle);
    }
