Question

I’m making an ASP.NET Web page that generates pages from SQL when they’re not cached. Their loading time could be between 300ms to 1.5seconds (No fix you database replies please).

I personally find these values to be too long, and was looking for a solution that allows me to inform the user that the page he is visiting will require a bit of time to load.

I was looking for a solution that could be via the Page_Load function, if that’s possible. The perfect solution for me in this case is showing the user either an animated GIF or text saying the page is being generated.

On a side note I come from programming mostly Windows applications.

Here is an example of how to use the Response object to flush content to the browser and continue processing:

using System; using System.Web.UI; using System.Threading;  public partial class _Default : Page {     protected override void OnLoad(EventArgs e)     {         base.OnLoad(e);          Response.Write('<h1>please wait...</h1>');         Response.Flush();          // simulate load time         Thread.Sleep(2000);          Response.Write('<h1>finished</h1>');     } }
