On clicking on Rating i need to display a radwindow or a popup with a textbox and button in it,a little bit similar to the one that you have given in your demo.http://demos.telerik.com/aspnet-ajax/rating/examples/rateandleavecomment/defaultcs.aspx.
The implementation of the desired scenario will be similar to the online demo Rate and Leave a Comment as you noted. The difference is that you will have to use the show() method of the RadWindow's rich Client API. For your convenience I have prepared a sample project, implementing the suggested approach. Please use it as a reference to incorporate this feature into your actual project.
Best wishes,
