ASP.NET TreeView auto expand?

Question

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.

Answer 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>

Answer 2

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;
    }
