                        </Columns>
                    </MasterTableView>
                </telerik:RadGrid>
                <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick"></asp:Timer>
            </ContentTemplate>
        </asp:UpdatePanel>

下面是c#Timer1_Tick:

 protected void Timer1_Tick(object sender, EventArgs e)
    {
        foreach (GridDataItem item in grd_transactions.Items)
        {
            Label lbl_Type_control = item.FindControl("lbl_Type") as Label;
            Label lbl_Status_control = item.FindControl("lbl_Status") as Label;
            Image img_Status_control = item.FindControl("img_Status") as Image;

            if (lbl_Status_control.Text != "Complete")
            {
                string[] time_array = lbl_Status_control.Text.Split(':');
                int hours = Convert.ToInt32(time_array[0]);
                int minutes = Convert.ToInt32(time_array[1]);
                int seconds = Convert.ToInt32(time_array[2]);
                int time_left_seconds = (hours * 3600) + (minutes * 60) + seconds;
                if (time_left_seconds > 0)
                {
                    time_left_seconds = time_left_seconds - 1;
                    TimeSpan timespan = TimeSpan.FromSeconds(time_left_seconds);
                    lbl_Status_control.Text = timespan.ToString(@"hh\:mm\:ss");
                    //lbl_Status_control.Text = timespan.ToString("H:mm:ss");
                }
                else
                {
                    lbl_Type_control.Text = "Payout";
                    lbl_Type_control.ToolTip = "Payout";

                    lbl_Status_control.Text = "Complete";
                    lbl_Status_control.ToolTip = "Double payment completed";

                    img_Status_control.ImageUrl = "~/Images/bitcoin-doubler-payout_icon.png";
                    img_Status_control.ToolTip = "Complete";
                }
            }
        }
    }

在timer_tick中,我创建了倒计时时钟


   (hh\:mm\:ss)

&每隔1秒更改RadGird Status列的标签。

问题是,当用户在每次勾选中用鼠标选择一行或列中的标签文本时,该选项消失&用户失去选择&感受计时器的滴答声。
我应该用什么技巧来解决这个问题?
