Best Data annotation for a Decimal(18,2)

Question

I have a column inside my sql server 2008 wih type of Decimal(18,2). But on entity framework what is the best data annotation validation I can apply to this pro

Answer 1

This seems to be the correct answer ( the above answers either restrict valid numbers that can be inserted into a data type of Decimal(18,2) or cause compile errors if you apply them to your code -- please confirm for yourself):

Use the following two constraints together:

Two Decimal Points

[RegularExpression(@"^\d+.?\d{0,2}$", ErrorMessage = "Invalid Target Price; Maximum Two Decimal Points.")]

Max 18 digits

  [Range(0, 9999999999999999.99, ErrorMessage = "Invalid Target Price; Max 18 digits")]
