Cellvalidating datagridview example


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?In a lot of books and articles that I've read on this control, it seems to suggest that the appropriate event to handle for this is the Cell Validating one. However, this event triggers a bit too often for my tastes and I'm not sure it is required.
