Remarks
If the ExpandToLevel method is used when the page is being loaded, call it after calling the tree list’s DataBind() method.
protected void Page_Load(object sender, EventArgs e) {
ASPxTreeList1.DataBind();
ASPxTreeList1.ExpandToLevel(3);
}
If the TreeListSettingsBehavior.AutoExpandAllNodes option is enabled, calling the ExpandToLevel method will have no effect.
