推荐答案

普拉萨纳.就像我看到的那样，您没有解释如何尝试将数据保存回数据库的过程.我建议您在"Page_Load"事件处理程序中设置代码，以使用"IsPostBack"检查其回发.像:

Hi Prasanna. Well as I see you haven''t explained the procedure how you''re trying to save the data back into the database. I suggest you to set your code inside "Page_Load" event handler to check if its a postback using "IsPostBack" . like:

protected void Page_Load(object sender, EventArgs e)
{            
  if (!IsPostBack)
  {
    // code goes here.
  }
}

这背后发生的事情是，每当服务器端控件首先创建一个回发事件时，它就会执行Page_Load事件.

希望对您有帮助.

What happens behind this is each time a server side control creates a postback event first it executes the Page_Load event.

Hope this help you.
