推荐答案

您可以使用您LoginView控件FindControl方法，让他们...

you can use the FindControl method on your loginview control to get them...

TextBox t = (TextBox)LoginView2.FindControl("TextBox1");
string s = null;

if (t != null)
{
    // textbox is in the current scope of the LoginView
    s = t.text;
}
else
{
    // the textbox is not in the current scope of the LoginView.
}

然而，这将仅对于目前在LoginView控件的所示视图中的控制工作。你必须测试你展示鉴于登录试图抓住文本之前，或者你也可以测试该的FindControl不返回空引用。

However, this will only work for the controls that are currently in the shown view of the LoginView control. You'd have to test that you're showing the logged in view before trying to grab the textbox, or you could also test that the FindControl doesn't return a null reference.
