error provider is not blinking uniformly

Question

I have an error provider providing error for 4 controls..

when I set all the four errors, only two of them blink together at a time and all four settle down after certain time..

even if I set two errors, both blink alternatively..

but I want all of them blink together...How can I do this? (I don't prefer using more than one errorProvider)

Answer 1

You've hinted to an (IMO) acceptable solution, with your last statement: use 2 error providers, one dedicated to blinking exactly one control at a time (the latest one with an invalid input, or the one you'd expect to be corrected ASAP, or whatever criteria you deem most important), and a second one that "silently" displays the icon on all controls with invalid input.
