I had a hard time finiding nodes so I wrote this and maybe EO should add to tree component.

The 2nd function is a recursive call to search entire tree not called directly by code in most cases.


Function FindNodeByValue(ByVal Tree As EO.Web.TreeView, ByVal inValue As String) As EO.Web.TreeNode

FindNodeByValue = Nothing
For Each tnode As EO.Web.TreeNode In Tree.Nodes

If Trim(inValue) = Trim(tnode.Value) Then
FindNodeByValue = tnode
Exit Function
End If
FindSubNodeByValue(tnode, inValue, FindNodeByValue)
If FindNodeByValue IsNot Nothing Then
Exit Function
End If

Next
End Function

Sub FindSubNodeByValue(ByVal Node As EO.Web.TreeNode, ByVal inValue As String, ByRef NodeRef As EO.Web.TreeNode)

For Each tnode As EO.Web.TreeNode In Node.SubGroup.Nodes
If Trim(inValue) = Trim(tnode.Value) Then
NodeRef = tnode
Exit Sub
End If
FindSubNodeByValue(tnode, inValue, NodeRef)
If NodeRef IsNot Nothing Then
Exit Sub
End If
Next
End Sub
