Answer 1

You can do below javascript code in order to set from javascript.

function setCombo() {
    var combo = $find("<%= cmbFault.ClientID %>"); 
    combo.set_text("S");
}

And also you can have a look http://www.telerik.com/help/aspnet-ajax/combobox-client-side-radcombobox.html

Answer 2

To get the control inside GridTemplateColumn do the following. JS:

function setCombo() {  
        var grid = $find("<%=RadGrid1.ClientID%>");  
        var tableView = grid.get_masterTableView();  
        var items = tableView.get_dataItems();  
        for(var i = 0; i<items.length; i++){  
            var rowValues = items[i]; 
            var Textvalue=rowValues.findElement("cmbFault");//access Combobox 
         }  
    }
