No I didn't mean to do at runtime. It's very hard to do that way. Let's walkthrough a sample :)
-Create a new form, set Datasession to Private and add orditems, products to DE (delete relation - don't need it)
-Create grid for orditems, selecting all fields in DE and drag&drop on form
-Now we have a plain grid browsing orditems
-Create a combo control on form (this is temporary but easier to play when not in grid)
-Using builder set this combo's fields to products.Prod_Name, product_id, Style dropdown list, controlsource = orditems.product_id, boundcolumn=2
-Select combo and Copy (or Cut)
-Edit grid and select product_id column and paste
-Change Product_ID columns controlsource to (as written in PEM sheet):

(iif(seek(orditems.product_id,'products','product_id'),products.prod_name,''))

-AFTER this set bound = .f.
-Go and change combo's controlsource back to orditems.product_id (should have changed to other iif(...
-Set current control to combo
-Increase rowheight slightly
-Run

>>>I'd love to see this work. Thanks Cetin keep you posted. I guess we had discussed sparse before, but I have some mental block against sparse as it modifies the grid's appearance and then you have to set cbo properties of style & others to make it look normal <g>.
