您好
如果您正在使用母版页，则必须从母版页访问它，如下所示

Hi
If you are using master page then you have to access it from the master page as below

if (!IsPostBack)
{
    MenuItem mItem1 = new MenuItem();
    mItem1.Text = "Test Menu";
    Menu menu = (Menu)this.Master.FindControl("NavigationMenu");
    menu.Items.Add(mItem1);
}

我认为vb.net可能像Dim menu as Menu= Me.Master.FindControl("StepPlanMenu1")

I think vb.net it may be like Dim menu as Menu= Me.Master.FindControl("StepPlanMenu1")
