Infragistics NetAdvantage for Web Client wbeetge [South Africa] 30-Aug-2010 12:12:04

I'd like to know how to achieve iteration through UltraWebTree nodes in ASP.net (VB) code-behind

Something like this would be good, if only it worked to hide all childnodes for a specific selected node:

Dim n as Infragistics.WebUI.UltraWebNavigator.Node

For Each n In UltraWebTree1.Nodes
If n.level > UltraWebTree1.SeletedNodes.Level
.....
n.Hidden = true
.....
End If
next

Hello there,

Thank you for using this Infragistics NetAdvantage for Web Client Forum here at ComponentSource.

I run your query with Infragistics and they sent the below answer for you:

===
The trees Nodes collection will only contain the root nodes, to loop through the child nodes, you would need to loop through the Nodes collection of a root tree node.

For example you could loop through all of the children of the first node with:

Dim n as Infragistics.WebUI.UltraWebNavigator.Node

For Each n In UltraWebTree1.Nodes(0).Nodes
If n.level > UltraWebTree1.SeletedNodes.Level
.....
n.Hidden = true
.....
End If
next

Note the only difference is in the For Each statement line.

Let me know if you have any questions with this matter.
===

I hope it helps.
