推荐答案

在按钮点击事件中，如果用户身份验证失败，设置文本框的文本属性并将标签设置为空字符串。

类似于：

In the button click event, if the user authentication fails, set the text propert of your textbox and label to empty string.
Something like:

protected void Button1_Click(object sender, EventArgs e)
{
    //if user authentication failed
    TextBox1.Text = "";
    Label1.Text = "";
    //lblErrorMessage = "Invalid Username or Password!";
}

标签是什么？



您还应该有一个标签通知用户身份验证失败（我在代码中添加了该注释）。

What is the label for?

You should also have a label which notifies the user about the authentication failure (I have added that as a comment in the code).
