Checking of objects are filled with data or not

E

Edwin Verwer

I have a form with 8 row of 5 objects namely:
Combobox | textbox | combobox | combobox | textbox

These objects are named:
Combobox(1 to 8) | Textbox(1 to 8) | Combobox(1 to 8) and so on.

Except for the first row all objects are disabled.

What i am trying to do is force users to fill in the objects in the first
row before the next row is enabled. This als counts for the rows that follow.

But it must also check if one of the objects in the previus rows
(if you have filled in multiple rows) is made empty.
If that is the case then the rows after the object that whas made empty must
have its data put in a array. The objects value must be made empty and then
the object must be disabled.

If that object is filled again and all the objects in that row are filled
then the rows that where disabled must be enabled again and the data in array
must be put back in these objects.

So it has to remember which rows where disabled and filled with data.

What is the best way to approach this?
