使用

如果您的页面是启用了Asp.net Ajax的页面(使用UpdatePanel).但是，如果您不使用UpdatePanel怎么办?

如何快速轻松地解决以下问题?

Using an UpdateProgress control is the correct option if your page is an Asp.net Ajax enabled page (With UpdatePanel). But, what if you don''t use UpdatePanel?

How about a quick easily solution as follows?

protected void Page_Load(object sender, EventArgs e)
{
           Response.BufferOutput = false; //Do not buffer page output. Write response immediately to the browser

           Response.Write(new string(' ', 256)); //Required for IE. 

           Response.Write("Processing...<br />"); //Show a fancy animation here, using an img html element or flash object
           Response.Flush(); //Flush response immediately

           Thread.Sleep(5000); //Mimics the expensive database operation for 5 seconds
           Response.Write("<br />Done."); //Indicate operation is done.
           Response.Flush();
}

当您在浏览器中点击页面时，将首先显示正在处理..."，并在5秒钟后显示完成"消息，而不会刷新任何页面. 5秒的延迟是由于Thread.Sleep(5000)引起的，您在此处调用数据库方法.

享受吧！

When you hit the page in the browser, the "Processing..." will be shown first and after 5 seconds the "Done" message will be shown without any page refresh. The 5 seconds delay is caused due to the Thread.Sleep(5000) and you call your database method here.

Enjoy!
