Treeview - retrieving node in the Expand event

[Kath]

Hello

I'm having problems getting the correct node in the
expand event

If I use:
Dim CurrentNode As TreeNode
CurrentNode = sender.nodes(e.Node.ToString)

CurentNode is always the top node despite e.node.tostring
changing from 0 to 0.1 or 0.0

Is this a bug or am I doing something wrong?

Thanks Kath

Hi Kath,

you must recursively dig into the tree to get the selected
node.

For example your selectNodeIndex value might look
something like: 1.1.0

then using the following code i get the selected Node.

Dim IndexArr As Array = SelectedTreeIndex.Value.Split(".")
Dim Count As Integer
Dim Node As TreeNode

Node = Tree.Nodes(CInt(IndexArr(0)))
Node.Expanded = True

For Count = 1 To IndexArr.Length - 2
Node = Node.Nodes(CInt(IndexArr(Count)))
Node.Expanded = True
Next

(think this is correct anyhow)

Hope it helps

Hi All,

sorry for my additional questiono I understand it right, that this code

Hi Manfred

The control is set to runat server so I'm hopeful that this code will
run server side!
