I have a scenario that involves opening a custom RadWindow from my main application as a modal display.  

From there, the user can enter some data which requires some validation.  

If the data doesn't validate, I am displaying a RadWindow.Alert("Some Message"), but the alert is appearing behind the calling custom RadWindow.

I've attached a screen shot that shows what is happening.  In the screen shot, the "Alert" window is being called by the "Select Route" window, yet it is behind the calling window and I am unable to acknowledge the alert.

What do I need to do to get the Alert to display on top of the custom RadWindow?

Hello Lee,

This is really strange behaviour. I tried to reproduce it in a sample application, but to no avail. Could you please give us some more details about your application: how you are calling the Alert window and how have you created the RadWindow, have you defined it in xaml or in a separate UserControl?
If you could reproduce this issue in a sample project and send it back to us, it would be really helpful.

Looking forward to your reply.

Konstantina, thank you for your reply.

I have created a sample application that demonstrates the behavior and attached it to a support ticket.  

The support ticket number is 349627.  

Is there something that I'm doing wrong?

I look forward to your reply.
