The little pleasures of a developers life ...
RangeAttribute throws a run time error in SetUpValidator(RangeValidator1) when a decimal sign is included and the client language is German; most likely a localization issue in the .NET 4.0 Dynamic Data Framework
// [RangeAttribute(0.0d, 9.999d]
Workaround using RegularExpressionAttribute; the supplied regular expression only supports German decimal number notation; I would use a global resource like Resources.Resource.MyRegex but this is not allowed since it's static but not const; only workaround I know about: using the InMemoryMetadataManager I found on the web - very useful if "dynamic" attributes are required
[RegularExpression(@"^[0-9](\,[0-9]{1,4})?$"]
public dynamic x {get; set; }
Final localized solution using InMemoryMetadataManager and my custom base class:
AddColumnAttributes(
p => p.x,
new RegularExpressionAttribute(Resource.FunctionCoordRegex)
{ ErrorMessage = Resource.InvalidFunctionCoordValue});
Method in generic base class:
static public void AddColumnAttributes(
Expression<Func<T, object>> propertyAccessor,
params Attribute[] attributes)
{
InMemoryMetadataManager.AddColumnAttributes<T>(propertyAccessor, attributes);
}
Just a few snippets so feel free to ask ... ;)
