Hi, I am having issue in the webdata tree node expand issue , some times node is expanding, somes times it is not working , when nodes are added dynamically. I am using the Infragistics asp.net 10.3 control set - Is there any issue with this version of control?

aspx Code :

 <asp:UpdatePanel ID="upPanel" runat="server">
                <ContentTemplate>
                    <ig:webdatatree id="wdtFPBrowser" runat="server" height="95%" initialexpanddepth="0" EnableViewState="true"
                        initialdatabinddepth="0" enableajax="true" enableconnectorlines="True" stylesetname="Default">
                                    <DataBindings>
                                    </DataBindings>
                                    <AutoPostBackFlags NodeExpanded="On" />
                                    <AjaxIndicator BlockArea="Page" Location="MiddleCenter" RelativeToControl="False" />
                                </ig:webdatatree>
                </ContentTemplate>
            </asp:UpdatePanel>

Code behind: On node expand event - adding the child nodes dynamically,

 DataTable dt = getNodes("Sub Node ");
            if (dt != null)
            {
                if (dt.Rows.Count > 0)
                {
                    //Get all of the folders that the user can see at the parent level
                    DataTreeNode dtNode;
                    foreach (DataRow dr in dt.Rows )
                    {
                        dtNode = new DataTreeNode();
                        dtNode.Text = dr["Text"].ToString();
                        dtNode.Value = dr["Value"].ToString();
                        dtNode.IsEmptyParent = true;                       
                        e.Node.Nodes.Add(dtNode);
                    }
                }               
            }
            e.Node.Expanded = true;

Thanks
