Asp.Net Dynamic Data – Validation Attributes

I’m leaving my musings on Linq-to-Sql for a moment and returning to dynamic data to cover off the validation attributes.

The table below lists the available attributes;

Attribute Description
RangeAttribute Specifies the numeric range constraints for the value of a data field in Dynamic Data.
RegularExpressionAttribute Specifies that a data field value in ASP.NET Dynamic Data must match the specified regular expression.
RequiredAttribute Specifies that a data field value is required.
StringLengthAttribute Specifies the maximum length of characters that are allowed in a data field.

To use these attributes you use them on a meta data class just like you do for the display attributes.

Over the next few posts I’m going to detail each of these attributes.
