How to add RadDocumentPane in code

[Klinger]

I have the following Silverlight xaml:

<radDock:RadDocking >
   <radDock:RadDocking.DocumentHost>
      <radDock:RadPaneGroup x:Name="ContentRegion" >
      </radDock:RadPaneGroup>
   </radDock:RadDocking.DocumentHost>
</radDock:RadDocking>

My question is:
How do I add a RadDocumentPane object to the ContentRegion (a RadPaneGroup) object in C# code?

I tried ContentRegion.AddItem(..) but I got an exception. Collection is readonly.

Which method should I use to add new content to the group?

Any help is appreciated.

Hello Klinger,

The logical parent of the RadPaneGroup always should be RadSplitContainer. The error you are getting is due to the fact that the parent of the RadPaneGroup has not been initialized. To make this work as expected pleadse use the code snippet shown below:  

<Docking:RadDocking x:Name="dock" Grid.Row="3" Grid.RowSpan="3" Grid.Column="0">
            <Docking:RadDocking.DocumentHost>
                <Docking:RadSplitContainer>
                    <Docking:RadPaneGroup x:Name="ContentRegion" />
                </Docking:RadSplitContainer>
            </Docking:RadDocking.DocumentHost>
        </Docking:RadDocking>

using System.Windows;
using System.Windows.Controls;
using Telerik.Windows.Controls;
using Telerik.Windows.Controls.Docking;

namespace SupportSL
{
    public partial class Page : UserControl
    {
        public Page()
        {
            InitializeComponent();

            dock.Loaded += new RoutedEventHandler(dock_Loaded);
        }

        void dock_Loaded(object sender, RoutedEventArgs e)
        {
            ContentRegion.AddItem(new RadPane() { Title = "test" }, DockPosition.Left);
        }
    }
}

Hope this helps.
