推荐答案

看人，我听不懂，但是按按钮时这很正常，页面必须回发或我认为即使您放下组合键并检查AoutoPostBack = false，我也刷新了.

还有另一种保存数据的方法，onButtonClick可以获取数据(例如:textBox)，并将其存储在viewstate或 session 中，然后您可以检查页面加载是否会话不为空，请给cobmo会话中的值

look man i dont understand correctly but it is normaly when you press a button the page must PostBack or refreshed i think even if you put the combo and check AoutoPostBack = false .

There is another way to keep the data, onButtonClick you can take the data (ex: textBox) and store is in viewstate or session then you can check in page load if the session is not empty give the cobmo the value in session

protected void Button2_Click(object sender, EventArgs e)
{
 if(!string.IsNullOrEmpty(txtBox.Text))
  {
    session["Value"] = txtBox.Text;
    ...
    ...
  }
}

and in 
protected void Page_Load(object sender, EventArgs e)
    {
       if (session["Value"] != null)
       {
         txtBox.text = (string)session["Value"]
       }
      Session.Remove("Value");
    }
Best Regards.

试试这个

将EnabledViewState="true"放在页面指令或所有控件中

Try this one

Place EnabledViewState="true" in page directive or to all the controls
