Thanks for your kind comments, too, by the way!

Cool glad you got it going. As for a grid, there is no such thing as a fast, fun, and easy way to go. But the two I would recommend would be the Infragistics UltraGrid and the DevExpress grid, in that order. I think that the Infragistics controls, especially teh grid, are better over all.



Remember that you will have to use the BusinessBindingSource to bind to any grid.

It is now working perfectly - thanks a million.

Which DATAGRID do you recommend if grid-editing is a must ??

I have experimented with the VS standard DataGridView, but don't find it as easy to use together with the StrataFrame setup.

Again - thanks for a super support on a super framework

Correct. That is what a smallint will be typed as. Just recast it as an int and you will be fine.

It looks like it's seeing it as a SHORT in the debugger!

  this.CurrentRow["tr_status"] 0 object {short}

Yes. Enums, by default, are typed as int. You can manually cast this, though:

In the database tr_status is a SmallInt - could that be the problem ?

What type is tr_Status? How is it defined in the database and what it the type in the CurrentDataTable when it comes back?

OK - I had the Inherited UI in my project and after this have been removed from the REFERENCES I don't get the DevExpress error any more!!

I still have the error when opening the form containing the Custome Data Type

"InvalidCastException: Specified cast is not valid"

>>>>  return (mbs2.Business.StatusType)this.CurrentRow["tr_status"];   <<<<<

Do I have to set anything special on the ComboBox properties when using a CDT'ed field.  The BindingField is still pointing to the field "tr_status". (PopulationEnumName=StatusType  PopulationType=Enumeration)

If you are referencing the MicroFour StrataFrame Inherited UI, then that is a DevExpress wrapper. This class is never touched outside of itself. So if you are receiving an exception through this class (the stack trace supplied) then the DevExpress control is in the formula at some point. You might double check that this is the case.
