Radgrid  data Grouping.

Step 1: Design web form .aspx page

  <div>

            <asp:ScriptManager ID="ss" runat="server"></asp:ScriptManager>

            <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" OnNeedDataSource="RadGrid1_NeedDataSource1" Width="50%"

                GridLines="None" PageSize="10" ShowGroupPanel="True">

                <MasterTableView TableLayout="Fixed" AutoGenerateColumns="true">

                    <GroupByExpressions>

                        <telerik:GridGroupByExpression>

                            <SelectFields>

                                <telerik:GridGroupByField FieldAlias="NAME" FieldName="NAME" FormatString="{0:D}"

                                   ></telerik:GridGroupByField>

                                <telerik:GridGroupByField FieldAlias="Amount" FieldName="Amount" FormatString="{0:D}"

                                   ></telerik:GridGroupByField>

                            </SelectFields>

                            <GroupByFields>

                                <telerik:GridGroupByField FieldName="NAME" SortOrder="Descending"></telerik:GridGroupByField>

                                <telerik:GridGroupByField FieldName="Amount" SortOrder="Descending"></telerik:GridGroupByField>

                            </GroupByFields>

                        </telerik:GridGroupByExpression>

                    </GroupByExpressions>

                    <Columns>

                    </Columns>

                </MasterTableView>

                <HeaderStyle Width="100px"></HeaderStyle>

                <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>

            </telerik:RadGrid>

        </div>

Step 2:Logic on .Cs page

protected void RadGrid1_NeedDataSource1(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

    {

        DataTable dt = new DataTable();

        dt.Columns.Add("Name");

        dt.Columns.Add("Amount");

        dt.Columns.Add("Phone");

        dt.Rows.Add("Kandy", "12", "8802***2564");

        dt.Rows.Add("Sam", "25", "545502*2544");

        dt.Rows.Add("Izhar", "2", "95802*2452");

        dt.Rows.Add("Vineet", "585", "88022564***");

        dt.Rows.Add("Kandy", "12", "8802***2564");

        dt.Rows.Add("Sam", "25", "545502*2544");

        dt.Rows.Add("Izhar", "32", "95802*2452");

        dt.Rows.Add("Vineet", "10.2", "88022564***");

        dt.Rows.Add("Kandy", "12", "8802***2564");

        dt.Rows.Add("Sam", "25", "545502*2544");

        dt.Rows.Add("Izhar", "32", "95802*2452");

        dt.Rows.Add("Vineet", "10.2", "88022564***");

        RadGrid1.DataSource = dt;

     }

It will look like :-
