Multi-Sorting in a Template column

[Paul]

Here's my following code:

<telerik:GridTemplateColumn UniqueName="UserName" DataField="FirstName" DataType="System.String" AllowFiltering="false" SortExpression="FirstName">
                <HeaderTemplate>
                      <asp:LinkButton id="btnName" runat="server"
                         Text="Name"
                         Title="Sort by Name"
                         CommandName='Sort'
                         CommandArgument='FirstName' />
                    </HeaderTemplate>
                    <ItemTemplate>
                                        <span class="ListTitle" style="font-size: 14px;">
                                        <%#Container.DataItem("FirstName")%> <%#Container.DataItem("LastName")%></span><br />
                                        <div class="QuestionDetails">
                                        <strong><%#Container.DataItem("EmailAddress")%></strong>
                                        </div>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>

It sorts properly and highlights the selected sorting column. I know that to do multiple sorting in a single template column you just add another link button with the new field to be sorted like similar to what this is doing here: http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/columntypes/defaultvb.aspx?#qsf-demo-source .The issue i see from that demo and my page is that it no longer highlights the sorted column if i add another link button in the header template. My question is how do i set it that it highlights if i select either sorting button?

Hello Paul,

Please try implementing Multi-Column Headers and let me know if it works for you:
