推荐答案

可能您必须检查按钮控件的有效性onClientClick.这在服务器端事件之前执行.但是，当您检查验证时，需要通过正确设置return false 来确保执行已停止.

类似的东西:

Probably you must be checking the validation onClientClick of button control. This executes before server side event. But when you check the validation, you need to make sure the execution is stopped by setting return false properly.

something like:

onClientClick = if(InValid(someEmail)) return false;

function InValid(checkEmail)
{
 // use your logic here and return true or false accordingly. 
}
