你这里能显示嘛?
<ContentTemplate>
<%= DateTime.Now.ToString()%>
<asp:Button ID="Button2" runat="server" Text="Button" />
</ContentTemplate>
</asp:UpdatePanel>
<ContentTemplate>
<%= DateTime.Now.ToString()%>
<asp:Button ID="Button2" runat="server" Text="Button" />
</ContentTemplate>
</asp:UpdatePanel><asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="1000" ontick="Timer1_Tick">
</asp:Timer>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>当前时间是:
<asp:Label ID="Lbtime" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
后台cs:
protected void Timer1_Tick(object sender, EventArgs e)
{
this.Lbtime.Text = DateTime.Now.ToString();
}
