I'm using the latest (2010) ReportViewer Web Control in an ASP.NET 4 project. My client wants me to suppress / hide the initial "Loading" message that gets displayed while the report is being fetched.
Yeah... I know... why hide information that tells you what's going on? But, the client wants what the client wants.
I know that if you use the report viewer control with AsyncRendering=False that you can then set the WaitControlDisplayAfter property to a ridiculously long value.
Unfortunately, I need to have AsyncRendering=True (showing multiple reports on a type of Dashboard thingy). This (according to MSDN http://msdn.microsoft.com/en-us/library/microsoft.reporting.webforms.reportviewer.waitcontroldisplayafter.aspx see Remarks section) will mean that the "Wait Control" will always show. (Grr-r-rr!)
So the question is, how to I not show this control using async rendering?
(An aside question the client asked me, was that they wanted to see a cached copy of the report while it's loading an updated one - any takers on this one?)
Thanks, Jaans
