It would be nice if we could show a processing like the below that comes out of the box in Sharepoint 2010 which says “Processing… Please wait while your changes are processed.”

This can be achieved programatically by the following code

SPLongOperation.BeginOperation beginOperation = null;

if (beginOperation == null)
{
    beginOperation = delegate(SPLongOperation longOperation)
    {
        // Long running code here .. 

        longOperation.End("settings.aspx", SPRedirectFlags.RelativeToLayoutsPage, HttpContext.Current, null);
    };
}
SPLongOperation.Begin(beginOperation);

longOperation.End() can be used to specify the redirect page when the operation ends. In the above example, it will redirect to the settings page of the site.
