I have a  XamDataGrid which is Bound to DataView as i dont know the fields (Its Dynamic)

but i want XamDataGrid to format Fields depend on their DataType ( Which Is also MYCustomdataType) & Formatting is also user Customizable LikE

MYCustomdataType1 which is a double internally but User can opt to show this value in many Diff Formats:-

10000 to (10,000) or -10-, I have a Class/service which handle this for me.

So if a Column of a dataview is of MyCustomDataType. it should get formatted as per the Object/Service Setting in GUI Only As i also Have Export To CSV feature So I cannot manipulate Actual Object Values at View Model before Binding it to Grid.

I tried the same via Changing Filed Class property:-

under FieldLayoutInitialized event

{

If(Field.DataType== typeof(MyCustomDataType))

Field.ConverterParameter = GetFormatStringFor(typeof(MyCustomDataType));
Field.Converter = new FormattingConverter();

 }

Its not working for me. Can you please help..
