Hi

I have a UIM where I handle a small CRUD to a table and I would like my UI buttons to have the following behavior:

- Add (Always Active)

- Delete (When there is at least one element in the table)

- Update (When there is at least one element in the table)

- Up (When there are at least two elements in the table)

- Down (When there are at least two elements in the table)

I was testing the buttons script but I couldn't do it. Could you help me?
