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.
