Refreshing parent RadWindow when child RadWindow is closed

[Srikrishna]

Hi Telerik,

In my application i can open a radwindow(parent) from a silverlight page. In this i have a RadGridView which displays list of users. From this window if i click a add button another radwindow(child) is opened in which i can add users. When i add a new user and close the childwindow the user added should be displayed in the parentwindow radgridview. Can you please help me with how can i achieve this?

Thanks in Advance.
