Hello,

I looked on the other threads that might solve this but I couldn't find an answer.

I have a "user control", called ctrlRadPaneGroup.xaml with the content:

    
            <telerikDocking:RadPane x:Class="telerikDocking.ctrlRadPaneGroup"
 
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
 
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
 
                xmlns:telerikDocking="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"
 
                xmlns:dragDrop="clr-namespace:Telerik.Windows.Controls.DragDrop;assembly=Telerik.Windows.Controls"
 
                xmlns:primitives="clr-namespace:Telerik.Windows.Controls.Primitives;assembly=Telerik.Windows.Controls"
 
                Width="60" Height="60">
 
                <telerikDocking:RadPane.Resources>
 
                    <DataTemplate x:Key="ApplicationDragTemplate">
 
                        <Image Source="{Binding IconPath}" Stretch="None" VerticalAlignment="Top" />
 
                    </DataTemplate>
 
                    <Style TargetType="ListBoxItem" x:Key="draggableItemStyle">
 
                        <Setter Property="HorizontalAlignment" Value="Stretch" />
 
                        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
 
                        <Setter Property="dragDrop:RadDragAndDropManager.AllowDrag" Value="True" />
 
                    </Style>
 
                </telerikDocking:RadPane.Resources>
 
                <telerikDocking:RadPane.Content>
 
                    <TextBlock>gigi</TextBlock>
 
                    <!--<ListBox Margin="10 10 10 10" Name="listboxInPane"
 
                                    dragDrop:RadDragAndDropManager.AllowDrop="True" BorderThickness="0"
 
                                    ItemContainerStyle="{StaticResource draggableItemStyle}" 
 
                                    ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Disabled">
 
                                <ListBox.ItemTemplate>
 
                                    <DataTemplate>
 
                                        <StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
 
                                            <Image Source="{Binding IconPath}" Margin="0 0 3 0"
 
                                                    HorizontalAlignment="Center" />
 
                                            <TextBlock Text="{Binding Name}" HorizontalAlignment="Center" />
 
                                        </StackPanel>
 
                                    </DataTemplate>
 
                                </ListBox.ItemTemplate>
 
                                <ListBox.ItemsPanel>
 
                                    <ItemsPanelTemplate>
 
                                        <primitives:RadUniformGrid Columns="3" HorizontalAlignment="Left"
 
                                                VerticalAlignment="Top" />
 
                                    </ItemsPanelTemplate>
 
                                </ListBox.ItemsPanel>
 
                            </ListBox>-->
 
                </telerikDocking:RadPane.Content>
 
            </telerikDocking:RadPane>

In the code behind I add another "user pane" but the content is null and the "gigi" string does not appear:

    
                        var newPane = new ctrlRadPaneGroup();
        
                        newPane.Header = "Pane " + numberOfPanes.ToString();
 
                        var groupPane = splitContainerLeft.Items[0] as Telerik.Windows.Controls.RadPaneGroup;
 
                        groupPane.AddItem(newPane, Telerik.Windows.Controls.Docking.DockPosition.Top);

The pane is added successfully in the interface, but as I said "gigi", or whatever control I wanted (a listbox in my case) does not appear.

What am I doing wrong? Thank you!

I have solved it, by making a small workaround. I have created a custom control that holds the listbox, and added the content programmaticaly after I creat the pane, but shouldn't the content of the pane be created once the custom pane was created?

    
                        var newPane = new RadPane();
 
                        newPane.Header = "Pane " + numberOfPanes.ToString();
 
                        var newListbox = new listboxApplications();
 
                        newPane.Content = newListbox;

Thanks!
