Recently I have been having trouble with a new system that went live a few weeks ago with users getting impatient with ajax postbacks and deciding that spamming the buttons will make things go faster…
Needless to say I was getting lots of exceptions in my elmah log. =(
It has quite a few cool features such as wait text, wait images, multiple panel update management and it works with .NET 4 & 3.5.
Happy Ajax.NET coding! =D
