推荐答案

从您所说的开始，听起来好像是在设置初始值，可能是在Page_Load事件中.

您应该将默认值括起来，例如:

From what you have said it sounds like you are setting the initial value, probably in the Page_Load event.

You should enclose the default values something like:

if (!IsPostBack)
{
    Label1.Text = value;
}

现在，当您单击按钮并回发时，新值将出现，因为仅在您首次进入页面时才设置初始值.

Now when you click a button and postback the new value will appear as the initial value is only set the first time you enter the page.
