ASP.NET MVC binding decimal value

Question

I\'m trying to figure out why framework refuses to bind \"1,234.00\" value to decimal. What can be the reason for it?

Values like \"123.00\" or \"123.0000\" bind suc

The issue here appears to be the default Number Styles applied to Decimal.Parse(string).

From MSDN documentation

The remaining individual field flags define style elements that may be, but do not have to be, present in the string representation of a decimal number for the parse operation to succeed.

So this means that both d1 and d2 below successfully parse

                var d1 = Decimal.Parse("1,232.000");

                var d2 = Decimal.Parse("1,232.000", NumberStyles.Any);

However when applying the type convertor it appears that this essentially only allows the allow training spaces, allow decimal point and allow leading sign. As such the d3 express below will throw a runtime error

                var d3 = Decimal.Parse("1,232.000", NumberStyles.AllowLeadingSign | NumberStyles.AllowLeadingWhite | 
                                        NumberStyles.AllowTrailingWhite | NumberStyles.AllowDecimalPoint);
