Can I trigger a cell_clicked event?

[zai yunfeng]

hi.
Can I trigger a cell_clicked event?Should I use MouseDown event instead?
I have another question about gridview.
When I select a row in gridview, is there any way to unselect this row only use a mouse? There is a control called ListCtrl in Visual C++. You can cancel a selection by click on blank area.

Thanks a lot.

Hi zai yunfeng,

You could trigger any type of event in WPF. For example, this will trigger MouseLeftButtonDown event:

MouseButtonEventArgs args = new MouseButtonEventArgs(Mouse.PrimaryDevice, 0, MouseButton.Left);
args.RoutedEvent = FrameworkElement.MouseLeftButtonDownEvent;
this.RaiseEvent(args);

The currently available selection modes do not allow deselection with the mouse only but you can easily implement that feature:

public partial class Window1 : Window
{
    public Window1()
    {
        InitializeComponent();
        this.myGrid.AddHandler(FrameworkElement.PreviewMouseLeftButtonDownEvent,
            new RoutedEventHandler(this.OnMouseUp) ,true);
    }

    private void OnMouseUp(object sender, RoutedEventArgs args)
    {
        FrameworkElement originalSource = args.OriginalSource as FrameworkElement;
        GridViewRow row = originalSource.ParentOfType<GridViewRow>();

        if (row != null && row.IsSelected)
        {
            row.IsSelected = false;
            args.Handled = true;
        }
    }
}
