You can turn off the scroll bars by using the property hidden in the style attribute of Treeview in the following way:

C#

protected void TreeView1_NodeExpanded1(object sender, TreeViewNodeEventArgs e)

    {

TreeView1.Attributes.CssStyle.Add(HtmlTextWriterStyle.Overflow, "hidden");

e.Node.Items.Add(this.BuildTree());

        TreeViewNode node = new TreeViewNode();

        node.Text = "LoadOnDemand";

node.ShowCheckBox = true;

        node.Checked = true;

node.ExpandMode = TreeViewNodeExpandMode.ServerSideCallback;

e.Node.Items.Add(node);

}

VB

Protected Sub TreeView1_NodeExpanded1(ByVal sender As Object, ByVal e As TreeViewNodeEventArgs)

TreeView1.Attributes.CssStyle.Add(HtmlTextWriterStyle.Overflow, "hidden")

e.Node.Items.Add(Me.BuildTree())

Dim node As TreeViewNode = New TreeViewNode()

node.Text = "LoadOnDemand"

node.ShowCheckBox = True

node.Checked = True

node.ExpandMode = TreeViewNodeExpandMode.ServerSideCallback

e.Node.Items.Add(node)

End Sub
