Auto row number in rad grid view

Hi you can this:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
       {
           if (e.Item is GridDataItem)
           {
               GridDataItem dataItem = (GridDataItem)e.Item;
               dataItem["RowNumber"].Text = Convert.ToString(grdState.PageSize * grdState.CurrentPageIndex + e.Item.ItemIndex + 1);

           }
       }

<columns>
    <telerik:gridboundcolumn uniquename="RowNumber" xmlns:telerik="#unknown"></telerik:gridboundcolumn></columns>

As vkeyan has posted, Add a column to Radgrid as

<telerik:GridTemplateColumn HeaderText="#" UniqueName="RowNumber">
                        <ItemTemplate>
                            <asp:Label runat="server" ID="lblRowNumber" Width="50px" Text='<%# Container.DataSetIndex+1 %>'></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>

<telerik:gridtemplatecolumn allowfiltering="false" headerstyle-width="30px" headertext="S.L.No" xmlns:telerik="#unknown">
<itemtemplate>

<%# Container.DataSetIndex+1 %>
