How to handle a left mouse button double click event?

[Rami Abughazaleh]

Hi.

I am wondering how to catch a left mouse button double click event and get the TreeListViewItem that was double clicked on?

Using Telerik Silverlight Controls v2010.1.422.1040



Thank you.

Hi Rami Abughazaleh,

The current CTP version of the TreeListView does not have a specific event that can be used. By the end of the week we will release the Q2 beta where you will be able to handle the

GridViewCell.CellDoubleClick

routed event.

Kind regards,

Dear sir or madam,

How is it possible to figure out if it is the left or the right button?

If I make a doubleclick like first leftbutton once then like the doubleclick but the second click on the right mousebutton, then the event is fired as a doubleclick. When I would like to show a contextmenu and click first with left mousebutton to select and quickly the right button for contextmenu, the doubleclick is fired.

How can I check if the doubleclick is really on left mouse button and not a mix of both?

Thank you very much
Best regards.

Hi,

 Please use RowActivated event instead. You can check the attached project for reference.

Thank you Vlad,

I've upgraded to RadControls for Silverlight 4 2010.2.714 but I am experiencing some unexpected behavior.

I've modified the previous attachment to reproduce the unexpected behavior as follows:

private void RadTreeListView_RowActivated(object sender, Telerik.Windows.Controls.GridView.RowEventArgs e)
        {
            Mouse.AddMouseUpHandler(e.Row, RadTreeListView_OnMouseUp, true);
        }

        private void RadTreeListView_OnMouseUp(object sender, Telerik.Windows.Input.MouseButtonEventArgs args)
        {
            if (args.ClickCount == 2)
            {
                var row = sender as GridViewRow;
                if (row != null)
                {
                    MyObject model = row.DataContext as MyObject;

                    MessageBox.Show(model.Name);
                }
            }
        }

The problem is that I do not get the message box when I double click within a cell that has data.  But if I click on any white space, it works.

Any ideas?

Thank you.
