The predefined dialogs (RadAlert, RadConfirm, RadPrompt) do not offer their own shortcut keys like the regular RadWIndows do, because they are very dynamic and multiple instances from the same template could be called in the same time.
What you can do is one of the following options:
1) use a regular RadWindow to show the alert infocmation (by setting proper behavior,s size and mimicking the alert's layout in the ContentTemplate - you could, for example, copy the markup from the AlertTemplate
). Then for this RadWindow you could declare a shortcut key that will close it (as explained here
). You may also find useful this article
on opening it from the server if this is where you obtain the message.
2) as you guessed - you can use a separate RadWindowManager and use its CloseAll command - this will also close the alerts from it without interfering with the windows from the main RadWindowManager.
All the best,
