    I'm trying to add a user control inside a dynamically created dock. My add method looks as follows:

    private RadDock CreateRadDock(string title, string contentURL, string forbiddenZone)
        {
            RadDock dock = new RadDock();
            dock.DockMode = DockMode.Docked;
            dock.UniqueName = Guid.NewGuid().ToString().Replace("-", "a");
            dock.ID = string.Format("RadDock{0}", dock.UniqueName);
            dock.Title = title;
            dock.Width = Unit.Percentage(100);
            dock.ForbiddenZones = forbiddenZone.Split(',');

            //dock.Commands.Add(new DockCloseCommand());
            dock.Commands.Add(new DockExpandCollapseCommand());

            Panel pnlDockContent = new Panel();
            pnlDockContent.ID = "Content" + dock.UniqueName;
            pnlDockContent.Controls.Add(LoadControl(contentURL));
            //dock.ContentContainer.Controls.Add(pnlDockContent);
            
            StringBuilder sb = new StringBuilder();
            StringWriter tw = new StringWriter(sb);
            HtmlTextWriter hw = new HtmlTextWriter(tw);

            pnlDockContent.RenderControl(hw);
            dock.Text = sb.ToString();
            
            return dock;
        }

    This works fine if the user control i'm loading doesn't have any Asp.Net controls. But whenever there's an Asp.Net control inside, the pnlDockContent.RenderControl call fails & that's obvious. The issue for which i had to chose this way is if the dock content is added as a control, the content doesn't persist on drag & drop of the dock. Can someone please help me with this?

    Hi,

    You could use the XmlHttpPanel control to load the user control inside the dock. Simply place the XmlHttpPanel within content container of the dock, and load the user control inside the XmlHttpPanel. Please explore our online demos for more information on RadXmlHttpPanel: http://demos.telerik.com/aspnet-ajax/xmlhttppanel/examples/default/defaultcs.aspx.
