:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<fieldset>
<legend>UpdatePanel</legend>
<asp:Label ID="Label1" runat="server" Text="Initial page rendered."></asp:Label><br />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</fieldset>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>
Processing...
</ProgressTemplate>
</asp:UpdateProgress>
在您的代码中:
protected void Button1_Click(object sender, EventArgs e)
{
// Introducing delay for demonstration.
System.Threading.Thread.Sleep(3000);
Label1.Text = "Page refreshed at " +
DateTime.Now.ToString();
}
这应该有效,试试吧......
