Asp. NET validation of control failures __.net

I've had this problem before and I solved it. The following is my analysis:

The cause of the problem: your local machine and the version of the. NET Framework installed on the server are not the same.
Because ASP.net validation control validation is supported by. js files within the aspnet_client of the. NET Framework.
A different version of the. NET framework results in subtle differences in the files within the aspnet_client, which can result in partial validation of the ASP.net validation controls being invalidated. For example, the. NET Framework version of my local machine: 1.14322.573. The. NET Framework version of the server: 1.14322.2032.

Solution: First go to the next ASP.net probe, you can go to http://down.chinaz.com/S/6936.asp download. Look at the local and server. NET Framework versions. After getting the server. NET Framework version to find this version aspnet_client folder on the space. Your control should be able to do so.

Good luck.
