I'm working on C# 4.0, WPF. I have three ListView, and all three control have the same ItemContainerGenerator_ItemsChanged" event. So my problem is, when ever the event triggered, i have to find the host.

lst1.ItemContainerGenerator.ItemsChanged += new System.Windows.Controls.Primitives.ItemsChangedEventHandler(ItemContainerGenerator_ItemsChanged);

lst2.ItemContainerGenerator.ItemsChanged += new System.Windows.Controls.Primitives.ItemsChangedEventHandler(ItemContainerGenerator_ItemsChanged);

lst3.ItemContainerGenerator.ItemsChanged += new System.Windows.Controls.Primitives.ItemsChangedEventHandler(ItemContainerGenerator_ItemsChanged);


 void ItemContainerGenerator_ItemsChanged(object sender, System.Windows.Controls.Primitives.ItemsChangedEventArgs e)
        {

         //TODO: Find host and proceed.

          **REAL Problem**


 // ListViewItem's Visible property has been set based on the deletion button click,
 // So at one place i have to get the count of rows which are visible and proceed
 // with related buttons enable/disable operation.
        }
