Just a quick question, I have an application that has about 15 textboxes and 5 checkboxes contained in 3 groupboxes. What I want to do is only enable the 'Save' button once all the required information has been added (basically I want to prevent partial submissions).

I'm using an ErrorProvider to check the textboxes but this only works when the textbox has focus. I'm thinking of using a timer event to check through the textboxes and enable the 'Save' button once all the conditions are met, is this a good way of doing it ?
