I'm using the enclosed code to change the font of a Label. When right clicking the label shows a context menu. Only the click events isn't triggered when clicking a menu item. Nothing happens...
I'm using VS2005 Beta 2. (And new to C#)

When I change the code a bit the following line appears:
throw new Exception("The method or operation is not implemented.");Maybe that explains why it doesn't work.

you need to put the font change code in the menuitems click event and not in the OnMouseDOwn event of the label..
Also the label object has a property "contextmenu" that will fire the referenced menu automaticallly on a right click

It's no problem to use the font change code on the click event. What I want is a context menu with more then one menuitems. Not only change the font, but also the color.
Using the referenced context menu to change the font works fine for a control that can have the focus, but not for a label. When I use it that way, the font of the control that has the focus changes, not the font of the label which is clicked.
