Hi,

I am trying to expand all the hierarchy items in the grid from the server side. I was able to expand the mastertableview rows to display the detail table. Each row in the detail table can expand to display the nested view. I am not able to get these rows expanded. Below is my aspx code for the grid
    
            <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" Width="700px"  
        
                        AllowMultiRowSelection="true"> 
        
                        <MasterTableView HierarchyLoadMode="ServerBind" GroupLoadMode="Server" Width="700px"  
        
                            DataKeyNames="ActionId" TableLayout="Fixed" Name="Actions" CommandItemDisplay="Top"> 
        
                            <CommandItemTemplate> 
        
                                <asp:Button ID="btnExpandOrCollapse" runat="Server" Text="Expand or Collapse" CommandName="expandallcollapseall" /> 
        
                            </CommandItemTemplate>                 
        
                            <Columns> 
        
                                <telerik:GridBoundColumn DataField="ActionName" HeaderText="Action"></telerik:GridBoundColumn>
