Read Html source of Radwindow Content

[Vipin]

Hello Telerik Team ,

I haven't used Radwindow much . And i have a requirement where i need to read the HTML content of the Url opened in Radwindow . 

I know i can do that using HTTP request  but in my case due to Security reasons i cant Bypass the Login screen , so the user first log in with credentials and then i need to read the html content of RadWindow .  I am pretty sure this can be done but i dont seem to find a way . 

Please suggest a way so that i can do that on server side button click event . 

Thank You
