UpdateProgress是一个进度显示条,加在AJAX里能显得更加的人性化(个人认为)。现在我们就开始吧: 第一.新建一个AJAX项目。在页面上加上ScriptManager,UpdatePanel,UpdateProgress,同时在UpdatePanel中加入一个Label,和Button。 第二:选中UpdateProgress的AssociatedUpdatePanelID设置为UpdatePanel1,完整的HTML代码如下:
<%@ Register
Assembly="AjaxControlToolkit"
Namespace="AjaxControlToolkit"
TagPrefix="ajaxToolkit"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
</div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Label" Width="166px"></asp:Label>
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button"/>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="testUp" runat=server AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate>
progressing

..
</ProgressTemplate>
</asp:UpdateProgress>
</form>
</body>
</html>
第三,在BUTTON中加入点击事件,代码如下:
System.Threading.Thread.Sleep(5000);
Label1.Text = DateTime.Now.ToString();
主要是故意创建一个延迟,显示效果。 最后,运行就ok了
