Focus Event Support static property to True: When this property is True, the support library ensures that the Lost Focus event is always fired after the Validate event.Notice that in the previously described scenario – the end user moves the focus away with the mouse but the control fails to validate – then a pair of Lost Focus/Got Focus events is fired anyway (unlike VB6), but this is seldom a problem.If the user enters invalid data they’ll see an icon shown in Figure 3.

Keyboard events provide access to this type of functionality.You do not have to disable the Form’s Auto Validate property.However, I prefer to call it explicitly and handle all validation at once since you most likely will take action only if the entire control’s children pass validation.

And, what should be Datasource Update Mode- On Property Changed or On Validation?
