UpdateProgress 应该就是“更新进度” 的意思吧。
使用方法:
1.添加一个ScriptManager控件
2.添加一个UpdatePanel控件
3.添加一个UpdateProgress控件
设置UpdateProgress控件的AssociatedUpdatePanelID为第2步 UpdatePanel的ID(如果页面中有多个UpdatePanel则,只有相应updatePanel关联的updateProgress显示)
测试例子代码:
复制代码 代码如下:

c#代码:
复制代码 代码如下:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Threading;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click1(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(3000);
Label1.Text = "刷新时间:" + DateTime.Now.ToString();
}
protected void Button2_Click1(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(3000);
Label2.Text = "刷新时间:" + DateTime.Now.ToString();
}
}
其中,页面代码中的css是msdn上的例子。UpdatePanel1中的UpdateProgress1显示一张动态gif图片
还往大哥大姐们多多指教。
