Cfgrid customization and notifications

I am working with HTML CFGRID as first time in CF9, I found that you can Delete, Update and Add records easier using this component.   But I have some questions about working with this feauture:                                                                                                                                                                                                                                                                                                -  Is there a way to validate form cells when trying to update or add the records? Validate maximum length and type.  -  When adding insert button it will create 2 more buttons cancel and save, Can i customize labels for that button? My app is spanish written.  - How would be the easiest way to style the grid - How can i notify the user when a record has been updated or can't be updated because of an error or a new record has been created?    I attach code for the cfgrid, I am using a component too.   ----------------------cfgrid -------------                                                                                                                                                                                                                                                                            ----------Component--------
