Keyboard focus problem in RadPane

[Piet]

I have a component (DiagramLite) that receives keydown events when inside a gridrow

When its inside a RadPane (See below) i donot get the keydown events.

The helpdesk of DiagramLite suggested looking for properties that could keep focus from the component (wich i could not find).

Any suggestion on where to search for a sollution ?

Below a part of the xaml:

Context is silverlight 2.0  telerik Q1 2009 diagramlite 1.02

thanks in advance,

Hi Piet,

What kind of keyboard events are you using in this component? I'd like to investigate the problem, but I don't know which events you need.

Hello,

I'am adding a keyDown event handler on bothe the complete diagram and on a box added to the diagram.

using MindFusion.Diagramming.silverlight.Layout;

diagram.KeyDown += new KeyEventHandler(diagram_KeyDown);

box.KeyDown += new KeyEventHandler(box_KeyDown);

Regards, Piet

Hi Piet,

I investigated the problem and what I found out was that the Diagram component did not get the KeyBoard focus even if it was clicked. The only way to focus it is to press the Tab key several times.
 
The Docking control uses tab controls in it and you have to press the Tab key a lot of times before getting to the Diagram and that is why you cannot handle the KeyDown event - it is really hard to move the focus to the Diagram.

This means that the problem is not in the Docking control, but in the Diagram control. Anyway, I found a workaround. You can handle the MouseDown event of the Digaram component and to force the focus to go to the component. Below is the code:

private void Diagram_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    (sender as Diagram).Focus();
}

Hope this helps.
