c# combobox filtering one combobox based on the value of another combobox

Question

Hi All.
I created form with two ComboBox. And I would like that selection in ComboBox1 filter ComboBox2.
Here is my code to populate ComboBox1:

public partial class Window1 : Window

{

MyDataSet ds = new MyDataSet();

MyDataSetTableAdapters.Table1TableAdapter tb1TableAdapter = new MyDataSetTableAdapters.Table1TableAdapter();

MyDataSetTableAdapters.Table2TableAdapter tb2TableAdapter = new MyDataSetTableAdapters.Table2TableAdapter();

BindingListCollectionView cvCombo1;

BindingListCollectionView cvCombo2;

public Window1()

{

InitializeComponent();

}

private void Window_Loaded(object sender, RoutedEventArgs e)

{

PopulateCombo1();

}

public void PopulateCombo1()

{

tb1TableAdapter.Fill(ds.Table1);

cvCombo1 = ((BindingListCollectionView)(CollectionViewSource.GetDefaultView(ds.Table1)));

CollectionViewSource cb1Source = FindResource("cvCombo1") as CollectionViewSource;

cb1Source.Source = ds.Table1;

}

public void PopulateCombo2()

{

tb2TableAdapter.Fill(ds.Table2);

cvCombo2 = ((BindingListCollectionView)(CollectionViewSource.GetDefaultView(ds.Table2)));

CollectionViewSource cb2Source = FindResource("cvCombo2") as CollectionViewSource;

cb2Source.Source = ds.Table2;

}

}

How to filter ComboBox2?

Thanks.

Windows Forms is not currently supported here on QnA. I'd try asking for help in dedicated forums here.
