ASP.NET TreeView auto expand?

Does anyone know how to show a asp:TreeView always expanded to the leaves? So if I have a 2-level tree, I want it to be expanded at all times. Is there a property on TreeView that does this or could you show the code snippet on how to do this?

Thank you very much! Ray.

And you can use an Integer if you only want to show the roots item per defualt:

    protected void Page_Load(object sender, EventArgs e)
    {
        TreeView1.ExpandDepth = 1;
    }

aspx.cs:

protected void Page_Load(object sender, EventArgs e)
{
    TreeView1.ExpandAll();
}

if you also want to disable expand-collapse symbols in the tree:

<asp:TreeView ID="TreeView1" runat="server" ShowExpandCollapse="false">
</asp:TreeView>
