Rad Grid Sorting highlight issue

[Alexey]

Hi all,

I am using Telerik RadGrid from Telerik.Web.UI (2008.2.826.35) assembly. I need to allow user to sort the data using only one column and highlight only this column. Hovewer, when grid highlights actual column (where sorting was applied by user) then the previous column (where sorting was applied before) remains to be highlighted. (see attachment).

I suspect that this is related to advanced sorting options, but setting flags bellow do not help (as described in the documentation).
AllowMultiColumnSorting="false" AllowNaturalSort="false" AllowCustomSorting="false"

I would be gratefull for any comments and suggestions. If there is a known bug in an old version of telerik assembly, please confirm it. (Looking through the demo examples on the telerik site with newer versions of rad grid, sorting highlight looks working fine).

Here is the code 

<telerik:RadGrid ID="rgSubscriptions" runat="server" ShowStatusBar="false"                     AllowAutomaticUpdates="True" GridLines="None" AllowPaging="True" PageSize="10"
                    AllowSorting="true" AllowAutomaticDeletes="True">
                    <MasterTableView TableLayout="Fixed" CellPadding="0" CellSpacing="0" DataKeyNames="ID"
                        AutoGenerateColumns="false" AllowMultiColumnSorting="false" AllowNaturalSort="false" AllowCustomSorting="false">
                         <SortExpressions>
                            <telerik:GridSortExpression FieldName="DateAdded" SortOrder="Ascending" />
                        </SortExpressions>
                        <Columns>
                            <telerik:GridTemplateColumn SortAscImageUrl="/AIMSGlobal/Images/sort_asc.gif" SortDescImageUrl="/AIMSGlobal/Images/sort_desc.gif"
                                ShowSortIcon="true" SortExpression="DateAdded" HeaderText="Date">
                                <HeaderStyle Width="100px"  />

                                    <%#GetDateFormatedString(Container.DataItem.DateAdded)%>
                                </ItemTemplate>
                            </telerik:GridTemplateColumn>
                            <telerik:GridBoundColumn DataField="Subscription.DataProvider.Name" HeaderText="Data Provider"

Hello Alexey,

I will suggest you to upgrade the version of RadControls for ASP.NET AJAX that you are using. It seems this behavior to be fixed in later versions.
