Hi,

I am not sure where you are trying the above given Javascript code. You must try the code in the aspx of the Content page. Also if you are using an RadControls for asp.net ajax you must access the Grid as shown below.

JS:

 var grid = $find("<%=RadGrid1.ClientID %>");

I'm using the RAD controls for Ajax
The javascript is in the content page itself
Now I'm getting the error:
          Error: grid.MasterTableView.SelectedRows is undefined
