Hi,

I have a list as below

-Branch
  Branchname = AB
  BranchCode = 01
  -Counters
     -Countername = AB-1
      Countercode = 101
      countername = AB-2
      countercode = 102
   Branchname = CD
   BranchCode = 02
     -Counter
         -Countername = CD-1
          Countercode = 201
          countername = CD-2
          countercode = 202

i have 2 listboxes in UI, first list box should load all the branches and the second list box should have the corresponding counters for the selected branch.

Can anyone help me in binding the nested listbox to 2 listbox.

Thanks,
Rajeeva

You have to use a objectdataprovider to bind the xml to the listbox. You can bind the branches to the first listbox . When an item is selected in the first listbox, its corresponding counters can be loaded in second list box using the "selecteditem" context.

This url should give you more details.  http://msdn.microsoft.com/en-us/magazine/cc163299.aspx

Try the following and see how it works for you.  Note that I made some assumptions regarding the structuring of your objects.

MainWindow.xaml
<Window x:Class="EE.Q_28544482.Wpf.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        DataContext="{Binding RelativeSource={RelativeSource Self}}"
        Title="MainWindow" Height="350" Width="525">
    <StackPanel>
        <ComboBox Name="CbBranches" VerticalAlignment="Top" Margin="10" ItemsSource="{Binding Branches}">
            <ComboBox.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding BranchName}" />
                </DataTemplate>
            </ComboBox.ItemTemplate>
            </ComboBox>
        <ComboBox Name="CbCounters" VerticalAlignment="Top" Margin="10" ItemsSource="{Binding ElementName=CbBranches, Path=SelectedItem.Counters}">
            <ComboBox.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding CounterName}" />
                </DataTemplate>
            </ComboBox.ItemTemplate>
        </ComboBox>
    </StackPanel>
</Window>
