计时器刻度不按时间间隔增加值 [英] Timer Tick not increasing values on time interval

问题描述

我想增加计时器滴答事件的值，但没有增加，不知道我忘记了什么，它仅显示1.

I want to increase values on timer tick event but it is not increasing don't know what I am forgetting it is showing only 1.

<asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="1000"></asp:Timer>

private int i = 0;

protected void Timer1_Tick(object sender, EventArgs e)
{
    i++;

    Label3.Text = i.ToString();
}

推荐答案

您可以使用ViewState进行存储，然后再次读取i的值.

You can use ViewState to store and then read the value of i again.

int i = 0;

protected void Timer1_Tick(object sender, EventArgs e)
{
    //check if the viewstate with the value exists
    if (ViewState["timerValue"] != null)
    {
        //cast the viewstate back to an int
        i = (int)ViewState["timerValue"];
    }

    i++;

    Label3.Text = i.ToString();

    //store the value in the viewstate
    ViewState["timerValue"] = i;
}
