ISSUE:Add a new RadPane to Docking when Loadlayout

[lee hom]

Hi,telerik.
    Here is a problem of the Docking Loadlayout.
    First, click the "Add New Item" button add some panel.
    Second,click the "Save Layout".At this time,click "Add New Item" button can add a panel to Docking.
    Now, click the "Load Layout" button,then click the "Add New Panel" button,there is no panel added to the Docking...
    Oh,the Title should be:"Can't Add a new RadPane to Docking After LoadLayout"

Here is the xaml

        private void radButton1_Click(object sender, RoutedEventArgs e)
        {
            RadPane rp = new RadPane();
            rp.Header = DateTime.Now.ToString("yyyyMMddHHmmssfff");
            rp.Title = rp.Header;
            RadDocking.SetSerializationTag(rp, rp.Header.ToString());
            ((Telerik.Windows.Controls.RadPaneGroup)((Telerik.Windows.Controls.RadSplitContainer)Docking.DocumentHost).Items[0]).Items.Add(rp); 
       }

OK,I Find where is the Problem is. After LoadLayout,the refrence is changed.

Hello,

 
Yes, you are right - when the layout is loaded, the reference to that RadPaneGroup is changed. I would suggest you to add a SerializationTag to this group as well. This will resolve the problem:

<telerik:RadPaneGroup x:Name="GroupDocument" telerik:RadDocking.SerializationTag="documentGroup">
 </telerik:RadPaneGroup>

Kind regards,
George
