关于Timer 定时器的使用问题.请教高手,急.!!!
我在添加好Timer控件后,进行了初始化的参数设置,<asp:Timer ID="tm" runat="server" Interval="5000" Enabled="true" EnableViewState="true" OnTick="tm_Tick" >
然后在.cs文件中写入如下代码: 
  protected void Page_Load(object sender, EventArgs e)
  {
  this.Label1.Text = "";
  }
  protected void tm_Tick(object sender, EventArgs e)
  {
  this.Label1.Text = "2gff";

  }

怎么这个定时器就不起作用啊 ?
请教高手,最好能详细点..

------解决方案--------------------
前端:
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtName" runat ="server" ></asp:TextBox>
<asp:Button ID="btnAdd" runat ="server" Text ="添加" OnClick ="Add_Res" />
</div>
<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Enabled ="true" Interval ="50" OnTick ="T_Tick">
</asp:Timer>
</form>

后端:
protected void T_Tick(object sender, EventArgs e)
{
btnAdd.Enabled = false;
btnAdd.Text = "Enable";

}

我的运行很正常
