Hello Jesmon,

Here is the sample code to create RadDock dynamically which worked as expected. Please elaborate your scenario if it doesn't help.
aspx:

<telerik:RadDockZone ID="RadDockZone1" runat="server">
</telerik:RadDockZone>

C#:

protected void Page_Load(object sender, EventArgs e)
{
  RadDock dock = new RadDock();
  dock.ID = "dock1";
  RadDockZone1.Controls.Add(dock);
}

Thanks,
Shinu.

Hello Shinu,
                    I am using Telerik.Web.Ui version is 2011.1.519.35.   and taking the sample from telerik demo site for creating the dynamic RadDock.  In CreateRadDock() 
                private RadDock CreateRadDock()
        {
            int docksCount = CurrentDockStates.Count;

            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 = "Dock";
            dock.Text = string.Format("Added at {0}", DateTime.Now);
            dock.Width = Unit.Pixel(300);

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

            return dock;
        }
DockMode showing the error like could not contain the definition for 'DockMode'. same for dock.Commands also
and I just commented these line and executed then showing the compile error like " Telerik.Web.UI.RadDockZone can contain only controls of type Telerik.Web.UI.RadDock   "
please help

Thanks

Hello Jesmon,

Note that the RadDockZone can contain only RadDock controls. It appears that you are inserting additional elements or controls in the dock zone which results in the encountered error. I would suggest ensuring that you add just a RadDock controls in the RadDockZone. The approach shown in the following code snippet is recommended for docking a dynamically created RadDock:

RadDockLayout1.Controls.Add(dock); // the RadDock is included in the Controls collection of the RadDockLayout
dock.Dock(RadDockZone1); // the dock is inserted in a RadDockZone via its method Dock

 
This method is used for creating and adding the RadDock controls in the online demo Dock / My Portal.

Also, keep in mind that you should create the RadDock controls before the event RadDock.DockPositionChanged, in order to ensure their proper operation, as stated in the help article RadDock Lifecycle. Usually, the best place to do thi is Init.

If you are still unable to resolve the problem after reviewing the presented information, please open a support ticket and send a simple, runnable page that isolates your case so that I can examine it locally and provide a working solution.

Kind regards,
