Why this method is never called when I clicked on a node of my ultraWebTree1
protected void UltraWebTree1_NodeSelectionChanged(object sender, WebTreeNodeEventArgs e){ e.Node........;}
I know it is easy, but I'm lost thanks you

Gabriel,
Unfortunately the UltraWebTree does not have an event that handles a mouse double click. If you would like to submit a feature request for this functionality, you can do so here.

Thanks you very much even if it is looking stupid. Your request helps me a lot. But one more little question, I saw onNodeClicked, but how can I catch the doubleClick event. Is it possible ?
Thanks you
HI,
There is a WebTree Property called Selectable - If this is set to false, then no nodes can be selected and the NodeSelectionChanged event will not fire.
Here is a help link:
http://help.infragistics.com/Help/NetAdvantage/NET/2008.3/CLR2.0/html/Infragistics2.WebUI.UltraWebNavigator.v8.3~Infragistics.WebUI.UltraWebNavigator.UltraWebTree~Selectable.html
Another possibility would be if you are using Manual LoadOnDemand.
Here is a sample program i created that shows the NodeSelectionchanged event will fire if it is properly wired up.
Here is my code behind:
using System;using System.Configuration;using System.Data;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Xml.Linq;
public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {
} protected void UltraWebTree1_NodeClicked(object sender, Infragistics.WebUI.UltraWebNavigator.WebTreeNodeEventArgs e) { Label1.Text = "clicked " + e.Node.Text; } protected void UltraWebTree1_NodeSelectionChanged(object sender, Infragistics.WebUI.UltraWebNavigator.WebTreeNodeEventArgs e) { Label2.Text = "selected " + e.Node.Text; }}
Here is the Aspx:
