- Attributes
The following code example brings the last child tree node of the last root tree node into view in the tree view when a button is clicked. This example requires that you have a TreeView control on a Form that contains a collection of TreeNode objects, and a Button. There should be enough tree nodes so that they are not all visible in the tree view control.
void button3_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
TreeNode^ lastNode = treeView1->Nodes[ treeView1->Nodes->Count - 1 ]->Nodes[ treeView1->Nodes[ treeView1->Nodes->Count - 1 ]->Nodes->Count - 1 ];
if ( !lastNode->IsVisible )
{
lastNode->EnsureVisible();
MessageBox::Show( String::Concat( lastNode->Text, " tree node is visible." ) );
}
}
private void button3_Click(object sender, System.EventArgs e)
{
TreeNode lastNode = treeView1.Nodes[treeView1.Nodes.Count - 1].
Nodes[treeView1.Nodes[treeView1.Nodes.Count - 1].Nodes.Count - 1];
if (!lastNode.IsVisible)
{
lastNode.EnsureVisible();
MessageBox.Show(lastNode.Text + " tree node is visible.");
}
}
Private Sub button3_Click(sender As Object, _
e As System.EventArgs) Handles button3.Click
Dim lastNode as TreeNode
lastNode = treeView1.Nodes(treeView1.Nodes.Count - 1). _
Nodes(treeView1.Nodes(treeView1.Nodes.Count - 1).Nodes.Count - 1)
If Not lastNode.IsVisible Then
lastNode.EnsureVisible()
MessageBox.Show(lastNode.Text & _
" tree node is visible.")
End If
End Sub
