)

#Parameters

Name Type Description

An integer value that specifies the nesting level.

#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.
