How to set the GroupView control with no items selected when the button view is set to true?

3 Sep 20201 minute to read

When ButtonView is set to true, the user cannot set the selected index to -1 to make it as not selected. As an alternative, set the Button View to false as a default and in the GroupView’s MouseDown event or GroupViewItemSelected event, set the Button View to true.

C#

// Set Button View in the MouseDown event.

private void groupView1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) 

{ 

this.groupView1.ButtonView = true; 

}

VB

' Set Button View in the MouseDown event. 

Private Sub groupView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)

Me.groupView1.ButtonView = True

End Sub
