                                                <Columns>
                                                    <telerik:GridBoundColumn HeaderText="ListName" DataField="Name" UniqueName="ListName" />
                                                    <telerik:GridTemplateColumn UniqueName="Reorder">
                                                        <ItemTemplate><st:STButton ID="btnReorder" runat="server" CommandName="reorder" Text="Reorder based on sort" /></ItemTemplate>

Hi Joselina,

RadGrid’s hierarchy structure has been extended with buttons in the hierarchy expand column headers that allow all detail items on a given level to be expanded/collapsed. Please set EnableHierarchyExpandAll property of the RadGrid to true to enable it.

ASPX:

<telerik:RadGrid EnableHierarchyExpandAll="true". . >

Thanks,
Princy
