gridview masked text box seems broken

Hi Joe,

Thank you for contacting us. 

The events like RowFormatting and CellFormatting are fired every time when the cell`s visual state needs to be updated. If you use the snippet in the handler of the formatting event this can cause performance issues.   

I attached the samplefor type converter again to be available in the forum post as well.

Hope this will help you. Let me know if you have any other questions.

Regards,
