[Solved] No more MouseLeftButtonDown event in Q3

[Gerry]

The MouseLeftButtonDown event for a RadGridView could be captured in Q2, but does not fire anymore in Q3. Looks like it is intercepted by Telerik. It is not replaced by any other event either.

I used the MouseLeftButtonDown event to allow a user to click on a row of the gird that displayed customers. Then I would give him a function selection page, where he could select a function to be performed for the customer he clicked.

In actual fact I used the MouseLeftButtonDown event with a timer to simulate a double-click. The user could double click on a row of the customer table displayed in a RadGridView and then I would give him a function selection for the customer he picked.

Now I have no idea how to do this in Q3. Can you help? Is this a bug in Q3?

Hi Gerold,

You could find more information about this topic on our forums.

Excuse us for the inconvenience.

On a side note, you can use our Mouse class to easily detect mouse double clicks - just use the AddMouseButtonDownHandler method to subscribe for mouse down event and check the ClickCount property of the mouse events args. If the ClickCount variable equals 2 then a double-click was performed.

I'm sorry I'm not getting the MouseDown event. Here is my code. The OnMouseDown function is never entered, when I set a breakpoint even before the clickcount check.
 
I do enter the breakpoint if I double click on the header row, but that does me no good and even then the clickcount is always 1.

        private void UIRadGrid_RowLoaded(object sender, RowLoadedEventArgs evt)
        {
            Mouse.AddMouseDownHandler(evt.Row, OnMouseDown);
        }

        private void OnMouseDown(object sender, Telerik.Windows.Input.MouseButtonEventArgs evt)
        {
            if (evt.ClickCount == 2)
            {
            }
        }

OK I found it: the "true" was missing in the statement below.

Mouse.AddMouseDownHandler(evt.Row, OnMouseDown, true);

However I noticed that the clickcount is not correct in some cases. I don't know why and when. But I'm ok if I can just intercept a single click. I can detect double click with a timer myself.
