Greetings All
I am attempting to add a calculated field to a grid as can be done in a browse. Not having much luck.

I code my grids. I have provided sample code below:

x = x+1
.columns(x).width = 80
.columns(x).controlSource = "apInvItems.shopOrder"
.columns(x).header1.caption = DBGETPROP("apInvItems.shopOrder","FIELD","CAPTION")
x = x+1
.
.

I want to display in a grid column the dfference between the apInvItems fields: qtyOrdered and the qtyInvoiced. Short of creating a cursor with the calculation as a cursor column, can I assign to a grid column the calculated value:

 apInvItems.qtyOrdered - apInvItems.qtyInvoiced

Thanks in advance

Vince
