I have a nested grid and I want to expand it and collapse it with a parent row click. It expands with parent row click per default but if i want to close it (collapse it) i have to hold crtl. I want to be able to collapse it again on the parent row click without holding crtl button. How is that possible? Thanks

Hello,

You can change the visibility of the RowDetails manually like so:
this.clubsGrid.AddHandler(GridViewDataControl.MouseLeftButtonDownEvent, new MouseButtonEventHandler(OnLeftButtonDown), true);
    }
 
    private void OnLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        var row = (e.OriginalSource as FrameworkElement).ParentOfType<GridViewRow>();
        if (row != null)
        {
            if (row.DetailsProvider.Visibility == Visibility.Visible)
            {
                row.DetailsVisibility = Visibility.Collapsed;
                 
            }
            else
            {
                row.DetailsVisibility = Visibility.Visible ;
 
            }
        }
    }
