推荐答案

不要放一些数值的控制：例如

Do put some values in the controls: E.g.

<input id="txtDateTime" runat="server" value="2014-12-12" type="text" datetime="datetime"/>
<label id="lblJobCity" runat="server">Some Text goes here </label>

然后 txtDateTime.Value 和 lblJobCity.InnerText 将提供数据的服务器端

Then txtDateTime.Value and lblJobCity.InnerText will provide data server-side

的更新的下面是完整的形式，使其工作：

UPDATE Here's complete form to make it work:

<form id="form1" runat="server">

   <input id="txtDateTime" runat="server" value="" type="text" datetime="datetime"  />
   <label id="lblJobCity" runat="server">Seattle</label>

   <input type="submit" id="submit" runat="server" onserverclick="submit_ServerClick" />
</form>

，然后检查事件的值：

And then check the values in the event:

protected void submit_ServerClick(object sender, EventArgs e)
{
    string a = txtDateTime.Value;
    string b = lblJobCity.InnerText;
}
