I hope you get what I mean Like Email Address(textbox) when user is typing his/her name in I [DON'T] want it to do validation yet, but when user has finished entering is waiting for Error Provider to disappear(But it doesn't coz it only does that when control loses focus) 2 odd seconds after typing can i make the validation take place?

I did find this thing here Counting Error Provider but incase someone knows a better way... Ok so basically I have a Win Form which has many Text Boxes Now when user enters values I use Validating to perform validation and if it does not match Regex I set the Error Provider ON for that Control..

similarly if the user changes the value to a acceptable one I switch Error Provider OFF for that Control..

but when SAVE is clicked i have to do another check anyways incase the user did not listen to me and change the thing like he was supposed to and still clicked SAVE.. soo mm is there like a thing where I could say if Error Providers is not active then proceed with save else message box saying change it.

[ANOTHER QUESTION] Umm When Validating it only Validates when the Control loses Focus...
