Expand/collapse Group when click on group header

Expand/collapse Group when click on group header

When I have a grid that groups items is there a way to expand/collapse the group when the user clicks on the text in the header? Right now the only way to expand/collapse a group is to click on the expand button in the header.

To accomplish your task handle the MouseLeftButtonUp event in the following manner:

[C#]Open in popup window

private void tableView1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) {            
TableView view = sender as TableView;            
TableViewHitInfo hi = view.CalcHitInfo(e.OriginalSource as DependencyObject);            
if (hi.HitTest == TableViewHitTest.GroupValue)                
ToggleExpandedState(view);        
}        

private void ToggleExpandedState(TableView view)        
{            
if (view.Grid.IsGroupRowExpanded(view.FocusedRowHandle))                
view.CollapseFocusedRow();            
else view.ExpandFocusedRow();        
}
