I am doing a prototype where I need to populate a TabGroupPane dynamically but via Binding instead of programmatically as shown in the xamFeatureBrowser.

In the XAML I have the following:

 <Window
    x:Class="DataboundTabGroupPane.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    
     
            xmlns:igDock="http://infragistics.com/DockManager"
  xmlns:local="clr-namespace:DataboundTabGroupPane"
    Title="DataBound TabGroupPane"
    Width="640" Height="380">
    <Window.Resources>
        <ObjectDataProvider x:Key="dataProvider"  ObjectType="{x:Type local:TabList}"/>
    </Window.Resources>
    <Grid Background="LightBlue">
        
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        
        <igDock:XamDockManager Grid.Row="0" x:Name="dockManager">
            <igDock:DocumentContentHost  >
                <igDock:SplitPane >
                    <igDock:TabGroupPane ItemsSource="{Binding Path=TabContent,Source={StaticResource dataProvider}}"  >


                    </igDock:TabGroupPane>

                </igDock:SplitPane>
            </igDock:DocumentContentHost>            
        </igDock:XamDockManager>
    </Grid>


</Window>

 

TabList.cs

using System.Collections.ObjectModel;
using System.Windows.Controls;
using Infragistics.Windows.DockManager;

namespace DataboundTabGroupPane
{
    public class TabList
    {
         ObservableCollection<ContentPane> _tabs = null;

        public ObservableCollection<ContentPane> TabContent
        {
            get
            {
                if (this._tabs == null)
                {
                   
                    _tabs = new ObservableCollection<ContentPane>();
                    ContentPane contentPane = new ContentPane    ();
                    contentPane.Header = "Document #1";
                    RichTextBox rtb        = new RichTextBox();
                    contentPane.Content=rtb;
                    _tabs.Add(contentPane);

                     contentPane = new ContentPane();
                    contentPane.Header = "Document #2";
                     rtb = new RichTextBox();
                    contentPane.Content = rtb;
                    _tabs.Add(contentPane);

                     contentPane = new ContentPane();
                    contentPane.Header = "Document #3";
                     rtb = new RichTextBox();
                    contentPane.Content = rtb;
                    _tabs.Add(contentPane);


                }

                return _tabs;
            }
        }       
    
    }
}

TabGroupPane gets populated but when trying to dragging one tab  I am getting the next exception. 

I can send you the VS project if you need it. 

 Thanks,
Claudio.
