I made a silly mistake regarding the MenuItem.Clik Event. As you rightly pointed out, I have to use the RadMenuItem.Click Event.
But now when I use the RadMenuItem.Click Event I cannot get the Item that has been Clicked. I manage to retrieve the latter by using the following workaround (I hope it might be helpful to somebody and it could save some time).
(1) Attach a MouseUp Event (You can use MouseDown Event but I think it is better to use MouseUp) to the RadMenuItem as follows:
(2) In the code-behind to get the Title of the RadMenuItem being clicked use the following code:
//((sender as Grid).Children contains the Image
//((sender as Grid).Children contains the Title
//((sender as Grid).Children contains the Summary
//To get the Clicked RadMenuItem's Title
Using this method I know which RadMenuItem has been Clicked by retrieving the Title. If there is a better way then I'm listening :)
Thanks for the help.
