I have a rad grid with a master (parent) and detailtable (child).

And I tried an example that was posted on another thread, but no matter what I try, I can't get get_nestedViews to work. It always returns error "Object doesn't support this property or method"

Here's the sample I tried....

the aspx..

    
            <script type="text/javascript" language="javascript">  
        
                        function getNestedViewsForFirstMasterItem() {  
        
                            debugger;  
        
                            var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();  
        
                            alert(masterTable.get_dataItems()[0].get_nestedViews().length);  
        
                        }   
        
                    </script> 
        
                    <asp:Button ID="Button1" runat="server" Text="GetNested" OnClientClick="getNestedViewsForFirstMasterItem();return false;" /> 
        
                    <telerik:RadGrid ID="RadGrid1"  GridLines="None" runat="server" OnNeedDataSource="radgrid1_NeedDataSource">  
        
                        <MasterTableView DataKeyNames="ID" Width="100%">  
        
                            <DetailTables> 
        
                                <telerik:GridTableView DataKeyNames="ID" /> 
        
                            </DetailTables> 
        
                        </MasterTableView> 
        
                    </telerik:RadGrid>

    
            protected void radgrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)  
        
                    {  
        
                        var dt = new DataTable();  
        
                        dt.Columns.Add("ID", typeof(Int32));  
        
                        dt.Columns.Add("Name", typeof(String));  
        
                        dt.Rows.Add(1, "test");  
        
                        dt.Rows.Add(2, "Another test");  
        
                        RadGrid1.DataSource = dt;  
        
                    }

This seemed so simple, but I can't get it to work.

Please help as I'm trying to access the nested/child tables via JavaScript in order to select the child rows when the parent row is selected. I have everything else working -- I have the selection/deselection of the parent row wired to a javascript function, I force teh parent row to be expanded if it isn't already -- I just can't seem to access the child/nested table to select all of its rows.

Thanks!
