I've written a small web db app, designed to sit within another page (in an iframe).
It is designed to be called with a parameter (or two).
iframe html calls Default.aspx?Parameter=4
The default page does nothing except check for the existance of the parameter and store it a session state variable before calling Page1.aspx.
Page1.aspx opens a connection to the db and pulls back a few hundred rows of data before figuring out what to display.
The problem / question: The call to the db takes a few seconds (particularly the first time it's called).
Can I display a "please wait" message while this call is executed? Is there a way to get Default.aspx to display before Page1.aspx starts the call? I'd rather avoid multiple threads if at all possible.
