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
Hi sivakuruba,
Please do not hesitate to contact me if you are still experiencing any issues.
Thank you for posting in the community.
I am so far unable to replicate the described behavior using version 11.2.20112.1019 and the last SR for version 10.3 - 10.3.20103.2217. It may be worth trying to disable AJAX on the data tree or, alternatively remove the update panel in order to see if that makes a difference. In order to research this further I would need a small working sample illustrating the behavior. Any additional information and steps to reproduce the matter would be appreciated.
Feel free to contact me if you have any questions.
