推荐答案

尝试在Page_Load中隐藏标签...

Hi,

Try to hide the label in Page_Load...

向页面添加一个隐藏变量，默认情况下将其设置为"N".

Add a hidden variable to the page, and by default set it to "N".

<asp:hiddenfield id="DisplayedAlready" runat="server" value="N" xmlns:asp="#unknown" />

和内部

and inside

protected void Button1_Click(object sender, EventArgs e)
{
     try
     {
       .......
        con.Close();
        if (DisplayedAlready.Value == "N") // not shown till now
        {
            DisplayedAlready.Value == "Y";
            Label2.Visible = true;
            Label2.Text = "Data has Been Successfully inserted";
        }
        else
        {
            Label2.Text = string.Empty; // or whatever you want to do second time
        }
        ......
     }
     catch (Exception es)
     {
          DisplayedAlready.Value = "N";
          // Label2.Text = "Error"; // ????? whatever you want to display
     }
}

另外，如果有任何重置情况，请记住将DisplayedAlready值重置为"N".
看看这是否适合您.

Also remember to reset the value of DisplayedAlready value to "N" if there is any reset case.
See if this works for you.
