Show the item name when selected the item id from lookup

Question

Dummy needs a help : )))))

I have an empty Grid with 2 fields, ItemId and ItemName, ItemId has lookup key.
How to make it possible when I select some itemid from lookup table to show its ItemName in another field?

Answer 1

On your table in the AOT, overwrite the modifiedfield method. For an example on how to overwrite, check the purchline.modifiedField method for example. Just add a case in the switch:

case fieldnum(YourTable, ItemId) this.itemName = inventtable::find(this.itemid).name(); break;

Unless really necessary, adding both the itemId and itemName is not needed, as you are de-normalizing the database at the point. It is probably better to add a display method for the itemname to your grid.
