I have a table called Products
This table contains a number of columns (some boring variables) and an PK column productID.
I have writting a function which needs the productID and then calculates the product-rate.
So: function getRate (byval productID as integer) as int32
this function is working: getRate(23) delivers the rate of product 23.
What I want now is show a datagrid with al the products, some or their properties AND the calculated rate.
The solution column.expressions doesn't work because the function was written by myself.
Eventually I want to store the value in the database, but first things first.
Perhaps my method to solve this is wrong, but please help??
