前台代码：

<div style="height: 143px; width: 545px">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Label ID="Label1" runat="server"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:Label ID="Label2" runat="server"></asp:Label><asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer2" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
<asp:Timer ID="Timer1" runat="server" Interval="3000" OnTick="Timer1_Tick">
</asp:Timer>
<asp:Timer ID="Timer2" runat="server" Interval="5000000" OnTick="Timer2_Tick">
</asp:Timer></div>

后台代码：

protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
GetDate();
}
}

private void GetDate()
{

}

protected void Timer1_Tick(object sender, EventArgs e)
{
Label1.Text = "UpdatePanel1 更新于： " + DateTime.Now.ToLongTimeString();
}
protected void Timer2_Tick(object sender, EventArgs e)
{
Label2.Text = "UpdatePanel2 更新于： " + DateTime.Now.ToLongTimeString();
}

想要UpdatePanel 定时更新，UpdatePanel2 输入时不被刷新
