试试这个

protected void Btn_SignUp_Click(object sender, EventArgs e)
        {//If not working properly set the visible attribute on button click also
            try
            {

                c1.SignUp(nametxt.Value, passtxt.Value, Convert.ToInt32(DropDownList1.SelectedValue), Convert.ToInt32(DropDownList2.SelectedValue),Convert.ToInt32(DropDownList3.SelectedValue),mailtxt.Value,numbtxt.Value);
                //GridView1.DataSource=ca.viewadmin();
                 Lbe6.Visible = true;
                 Lbe6.Text = (" Account Successfully Created");
                //  GridView1.DataBind();
            }
            catch
            {
               Lbe5.Visible = true;
               lbe5.Text = ("SIGNUP FAILED.PLEASE TRY AGAIN");

            }

如果您尝试隐藏标签，直到消息成功为真，请设置Lbe6.Visible = false，然后在设置消息成功时将其设置回Lbe6.Visible = true。

当点击按钮然后显示消息
