Locking Cells Using VB or Formula

[JohnH]

Is there a way to lock cells using VB based on the value of another cell. Example:

I have a list for data entry, if the value of the first cell in the row (A2)is equal to the value of the first row (A1) then I want to lock Cells C2 and D2. This will apply for all subsequent rows as data is entered.

What is the best way of doing this?


Thanks.

You may be able to use data validation for this. Go to your cell you want to lock, and choose validation from the data menu. On the setting tab, change the allow drop down to custom. Type in =A2<>A1 under the formula. You can also add custom input and error messages here if you choose.

Be aware that this will prevent a user from typing in a value if A1=A2, but it will not prevent a user from pasting a value here. If you need something more robust, VBA is needed.

Good luck.

Thank you both for the reply. The best solution for my purpose is using the Data Validation method.

Thanks.
