    Hi Gennaro,

    In your above given code you are trying to access the Grid as:

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

    Try accessing the Grid on the client as shown below:

     var grid = $find("<%= RadGrid1.ClientID %>"); 
     grid.set_activeRow(grid.MasterTableView.get_dataItems()[0].get_element()); 


    Thanks
    Shinu

    Hello Gennaro,

    Verify that if you are accessing the grid in javascript, it is being placed either outside of the head tag, or the head tag does not have a runat="server" attribute.

    Thanks
    Princy.

    What is the syntax if the javascript is outside of the head? e.g. in a UserControl. How do you find the control you are looking for?
