C control on validating
So could some demonstrate how when focus is lost on the field, if the data is not valid, a default value will be entered instead e.g.

The problem I am experiencing is when a control fails its validating event and the user clicks another tab things get messy. Drumm" all the controls on that tab have finished validating?

So I propose that you insert the list to the begin of the tutorial. In this example I am implementing an generic validation rule that takes a regular expression as validation rule. If the expression matches the data is treated as valid.
