Link button in grid column to UDO

Hi,

I read through the posts regarding linking to user-defined objects, but I found it very confusing. Some posts say that it is not possible to create a link button to a UDO; others say you need to use the extended-object property.

Does anyone have code that I could use to designate a grid column as a link to a UDO?

The code I'm using is:

oGrid.Columns.Item(1).Type = SAPbouiCOM.BoGridColumnType.gct_EditText

txtColumn = oGrid.Columns.Item(1)

txtColumn.Width = 83

txtColumn.LinkedObjectType = ???

I need to fill in the "???".

If I designate an SAP B1 object type it works.

Thanks,

Mike
