Question

I have this code to select first node of TreeView. But when page loads the by default root node is other than first, I want to set the selected node as top most by default. Here is my code in page load but it’s not working:

Dim nodes As TreeNodeCollection = TreeView1.Nodes
If nodes.Count > 0 Then
  ' Select the root node
  TreeView1.SelectedNode = nodes(0)                        
End If

This gives the blue underline error on this line:

TreeView1.SelectedNode = nodes(0)

The error is:

“Selected Node Property is read Only”

Please any one tell me how can I do this?

Answer 1

To select a node you need to set the selected property on the node itself:

nodes(0).Selected = true  

Equally you can use:

nodes(0).Select()
