First create a fieldgroup on the table which is shown in the Grid.
Then create a validateField() method on the table you want to be editable.
Now in that method, determine whether the value exists in the related table
(create an exist method in your tableTwo that returns a Boolean) and let
Axapta do the rest. You could use fieldNum(tableOne, fieldX) function to
check which field you want to be validated.

Onderwerp: [development-axapta] validate / modifed ?
Hello all,
This is a really simple problem, but somehow I
just could not make it. Here's an example:
I have two tables (e.g. "TableOne" and "TableTwo"), which both have
one textfield (let's call it "fieldX").
Then I have a grid in a form, where I have one column which data
comes from TableOne.fieldX.
I want to prevent that user can not _modify_ existing value in
TableOne.fieldX, IF the value exists in TableTwo.fieldX.
I think there's two ways to do it. First use a somekind of relation
in tables. Second, to put some simple code to this column in a grid,
e.g. into modified- or validate- methods.
With the code solution, I have this problem. How to get
the old value (the one that user modified)?
this.valueStr() gives me the new just typed value.
