I have been stuck for a few days and need advise. When the user selects a node I want to display the text of the childeren.

Sample code:

Private Sub TreeView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TreeView1.Click

TextBox1.Text = ""

TextBox1.Text = "Level = " & TreeView1.SelectedNode.Level
TextBox1.Text = TextBox1.Text & vbCrLf & "Index = " & TreeView1.SelectedNode.Index
TextBox1.Text = TextBox1.Text & vbCrLf & "Text = " & TreeView1.SelectedNode.Text

If TreeView1.SelectedNode.Level = 0 Then

TextBox1.Text = TextBox1.Text & vbCrLf & "Text = " & ??????????I NEED TO KNOW WHAT TO PUT HERE FOR THE CHILDREN

End If

End Sub

Just cycle through child nodes for selected node and add their text. Here is how:

Code:

If TreeView1.SelectedNode.Level = 0 Then
For Each node As LidorSystems.IntegralUI.Lists.TreeNode In TreeView1.SelectedNode.Nodes
TextBox1.Text = TextBox1.Text & vbCrLf & vbTab & "Text = " & node.Text
Next
End If

If the child nodes also have their own child nodes, then use a method:

Code:

ShowChildren(TreeView1.SelectedNode)

Code:

Private Sub ShowChildren(ByVal parentNode As LidorSystems.IntegralUI.Lists.TreeNode)
For Each node As LidorSystems.IntegralUI.Lists.TreeNode In parentNode.Nodes
TextBox1.Text = TextBox1.Text & vbCrLf

For i As Integer = 0 To parentNode.Level
TextBox1.Text = TextBox1.Text & vbTab
Next

TextBox1.Text = TextBox1.Text & "Text = " & node.Text

ShowChildren(node)
Next
End Sub
