Question

I have a ListView like:

Col1  Col2  Col3
1      A     I
2      B     II
3      C     III 

I use 2 buttons. When I click on the first button the Col3 should collapse and it should be visible when a click in the second button.

Any idea on how to do such a ListView in WPF?

Answer 1

Use of Thumb will solve the problem.
Just as

<ListView x:Name="MyListView"IsSynchronizedWithCurrentItem="True" 
    ItemsSource="{Binding Path=Items}",  Mode=Default, 
    Source={StaticResource DataProvider}}"  
    Thumb.DragDelta="Thumb_DragDelta">

public Window1()
{
   InitializeComponent();
   MyListView.AddHandler(Thumb.DragDeltaEvent,
               new DragDeltaEventHandler(Thumb_DragDelta),
               true );
}

void Thumb_DragDelta(object sender, DragDeltaEventArgs e)
{
   Thumb senderAsThumb = e.OriginalSource as Thumb;
   GridViewColumnHeader header = senderAsThumb.TemplatedParent as GridViewColumnHeader;
   if (header.Column.ActualWidth < MIN_WIDTH)
   {
      header.Column.Width = MIN_WIDTH;
   }
   if (header.Column.ActualWidth > MAX_WIDTH)
   {
      header.Column.Width = MAX_WIDTH;
   }
}
