waiting

[Aaron]

I have a search page that takes a long time to load, about 1 min.
How can I prompt the user with a 'please wait' and a progress bar right
after the user submit the search words?

Thanks
Aaron

Hi,

Perform the search during rendition process using threads.

protected override void Render(HtmlTextWriter writer)
{
System.Threading.Thread t = new System.Threading.Thread(SearchMethod);
t.Start();

writer.Write("Please wait...");

while(t.IsAlive)
{
writer.Write(".");
writer.Flush();

Page.Response.Flush();

System.Threading.Thread.Sleep(500);
}
}

This is simplest solution I've seen:

Beware of this solution as it consumes a thread from the thread pool for
the entire minute. This will cause performance problems in your application
if you also have moderate load. You might want to look into some of the other
solutions or take the idea of this approach below but make it an async page.
