Hi, I'm using the cellvalidating event on a datagridview.

I can’t seem to get my Validate The Entry() function to return a 0 if the entry is either “” or NULL or string. I only need to validate certain columns in the datagrid, I don’t need to validate the EAN or the description for instance and yet the column index don’t seem to be logical?
