Which event is best to format input string?

[Wellpartner]

I'm storing National Drug Code (NDC) in this format: #####-####-## (eg. 12345-6789-01), but would like to allow users to enter without the hyphens.  I've tried a GridViewMaskedTextBoxColumn, and while that enforces the pattern, the hyphens are omitted.  So I'm wondering which event would be best to intercept the data and insert the hyphens myself?

Hi,

 Why not implement this directly at your property getter/setter level? You can use also Data Annotations.

Thanks, Vlad - you're right, I can just do it in the setter.
