I guess everybody know that MS ASP.NET AJAX is having problem on.net validation controls.  This issues exists long time ago and become a hot topic in ajax.asp.net community forum. What happen to Microsoft? The final release is put up with no notice about the fact that this requires some other update which has not been released.

Now, there is a HotFix to solve this problem:

Does this mean that all my problems solved? Unfortunately, it is not. My web hosting upgraded ASP.NET AJAX from RC version to v1.0. That time, I have to recompile all my sources and upload it. Then, all my application’s validation failed.  Now, there is a HotFix from Microsoft.  But my hosting company does not want to install the patch due to overall stability reason.  In that case, if Microsoft does not release the update until end of the year, does this means that I need to use the corrupted AJAX version until that time?  I am waiting their reply after submit and explain my second request. If they still do not want to patch the HotFix, I think is time for me to switch away from them. This kind of AJAX features means nothing to us since the simple validation failed.
