推荐答案

检查你的Page_Load方法：我打赌你清除那里的字段。

Page_Load被调用所有页面活动，包括按钮点击引起的回发，所以除非你检查一下回复后，它们将在点击事件处理程序运行之前被清除。

Check your Page_Load method: I'm betting you clear the fields there.
Page_Load is called fro all page activities, including the postbacks caused by button clicks, so unless you check for a post back they will be cleared before the click event handler gets to run.

protected void Page_Load(object sender, EventArgs e)
    {
    if (!IsPostBack)
        {
        // Handle the initial page setup.

manage

ispostback on page load

and bind data on every submit
