The following code example demonstrates how to set the FrozenColumnCount property in code. This example is part of a larger example available in the Walkthrough: Customizing the DataGrid Control Using Properties topic.

Private Sub cbFreezeColumn_Changed(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)
    Dim cb As CheckBox = sender
    If Me.dataGrid1 IsNot Nothing Then
        If cb.IsChecked = True Then
            Me.dataGrid1.FrozenColumnCount = 1
        ElseIf cb.IsChecked = False Then
            Me.dataGrid1.FrozenColumnCount = 0
        End If
    End If
End Sub
private void cbFreezeColumn_Changed(object sender, RoutedEventArgs e)
    CheckBox cb = sender as CheckBox;
    if (this.dataGrid1 != null)
        if (cb.IsChecked == true)
            this.dataGrid1.FrozenColumnCount = 1;
        else if (cb.IsChecked == false)
            this.dataGrid1.FrozenColumnCount = 0;
