<script type="text/javascript">
 var selected = {};
            function RadGrid1_RowSelected(sender, args) {
                var StudentId = args.getDataKeyValue("StudentId");
                if (!selected[StudentId]) {
                    selected[StudentId] = true;
                }
            }
            function RadGrid1_RowDeselected(sender, args) {
                var StudentId = args.getDataKeyValue("StudentId");
                if (selected[StudentId]) {
                    selected[StudentId] = null;
                }
            }
            function pageLoad(sender, args) {
                var dataItems = $find('<%=RadGrid1.ClientID %>').get_masterTableView().get_dataItems();
                for (var i = 0, j = dataItems.length; i < j; i++) {
                    var item = dataItems[i];
                    if (selected[item.getDataKeyValue("StudentId")]) {
                        item.set_selected(true);
                    }
                }
            }
 </script>


<telerik:RadGrid ID="RadGrid1" runat="server">
 <MasterTableView  ClientDataKeyNames="StudentId">

 <ClientSettings   Selecting-AllowRowSelect="true" EnableRowHoverStyle="true">
                        <ClientEvents OnRowSelected="RadGrid1_RowSelected" OnRowDeselected="RadGrid1_RowDeselected" />
                    </ClientSettings>
