SetDataPath Client Side
posted

I am using ManualSmartCallbacks and would like to set the DataPath client-side in the DemandLoad event, but there doesn't seem to be an Method to do this.

I need to do this because DataPath is the only field that seems to stay around when populating a tree view the DemandLoad server-side event.  I'm setting data to the tag, but when that node is expanded the tag is not passed to the server.  In reading other posts, I noted that DataPath is the only field that is persisted throughout, so in my server-side code I set the DataPath property also.  I would like to be able to add additional client-side info and pass it up, but since I can't set DataPath, I seem to be restricted.

 I am using 2007-3, so maybe there's an appropriate method in 2008-3.

 Suggestions?

Thanks!

    Hello
    You can use the property Tag of node and set value. Please take a look code below:

    ASPX code:
     <ignav:UltraWebTree ID="UltraWebTree1" LoadOnDemand="ManualSmartCallbacks" runat="server"
            OnDemandLoad="UltraWebTree1_DemandLoad">
            <ClientSideEvents DemandLoad="Load" />
            <Nodes>
                <ignav:Node Text="R" ShowExpand="true">
                </ignav:Node>
            </Nodes>
        </ignav:UltraWebTree>

    JS code:  
     <script type="text/javascript">
            function Load(menuId, itemId) {
                var node = igtree_getNodeById(itemId);
                node.setTag("tag");

            }
        </script>

    C# code:
      protected void UltraWebTree1_DemandLoad(object sender, Infragistics.WebUI.UltraWebNavigator.WebTreeNodeEventArgs e)
        {
            Label1.Text = e.Node.Tag.ToString();

        }

    Hope this helps.
