In some circumstances a RadPaneGroup will not show content using a loaded layout. Can reproduce with controls version 2011.2.1010.1040 and 2011.3.1020.1040.
To reproduce:
- Dock the second pane on the right side of the split container (see docking_layout.png)
- Save the layout
- Refresh the application
- Load the layout
- Make the second pane hidden
- Make the second pane visible (see docking_problem.png)
Example XAML:

using System.ComponentModel;
using System.IO;
using System.Windows;
using System.Windows.Controls;
using Telerik.Windows.Controls;
namespace DockingPersistence
{
public partial class MainPage : UserControl, INotifyPropertyChanged
{
public MainPage()
{
InitializeComponent();
DataContext = this;
}
private bool _firstPaneIsHidden;
public bool FirstPaneIsHidden
{
get { return _firstPaneIsHidden; }
set { _firstPaneIsHidden = value; NotifyPropertyChanged("FirstPaneIsHidden"); }
}
private bool _secondPaneIsHidden;
public bool SecondPaneIsHidden
{
get { return _secondPaneIsHidden; }
set { _secondPaneIsHidden = value; NotifyPropertyChanged("SecondPaneIsHidden"); }
