How to view the hidden items in a GroupView programmatically?

GroupView’s BringItemIntoView method can be used to scroll down to a hidden item and bring that item into view.

this.groupView1.SelectedItem = 20; 

// This will scroll to Item 20. 

this.groupView1.BringItemIntoView(20);
Me.groupView1.SelectedItem = 20

' This will scroll to Item 20. 

Me.groupView1.BringItemIntoView(20)
