内のLoginView1コントロールにアクセスする方法は?Multiview1View2
マルチビュー内のView 2のloggedInテンプレートにテキストボックスとドロップダウンリストがあり、コントロールを取得してデータベースからテキストにバインドする必要があります。
私は試してみました：
((TextBox)this.LoginView1.FindControl("custEmail")).Text = dr.GetValue(1).ToString();
((TextBox)LoginView1.FindControl("custEmail")).Text = dr.GetValue(1).ToString();
((TextBox)LoginView1.FindControl("custEmail")).Text = "xxxx";
「オブジェクト参照がオブジェクトのインスタンスに設定されていません」を返します。
