Populate parent and childnode for selected node
This can be done by setting the SelectedNode to be the presentnode and then if the presentnode is equal to null, the new childNode is created and added.
C#
private void button1_Click(object sender, System.EventArgs e)
{
TreeNodeAdv presentNode = this.treeViewAdv1.SelectedNode;
if(presentNode == null)
return;
TreeNodeAdv newNode = new TreeNodeAdv("NewChild");
presentNode.Nodes.Add(newNode);
}
private void button2_Click(object sender, System.EventArgs e)
{
TreeNodeAdv newnode = new TreeNodeAdv("Parentnode");
this.treeViewAdv1.Nodes.Add(newnode);
}
VB
Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim presentNode As TreeNodeAdv = Me.treeViewAdv1.SelectedNode
If presentNode Is Nothing Then
Return
End If
Dim newNode As TreeNodeAdv = New TreeNodeAdv("NewChild")
presentNode.Nodes.Add(newNode)
End Sub
Private Sub button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim newnode As TreeNodeAdv = New TreeNodeAdv("Parentnode")
Me.treeViewAdv1.Nodes.Add(newnode)
End Sub
