I'm trying my hand at developing a Mobile App using a database. It's a simple application (just getting a feel for things) of data entry and storing it into a SQL Server Express DB. My question is this, what is the common practice for
keying in data in textboxes and then pressing a button to add the data to a DB.

I know in desktop development or even web development, it's common to press a command button to perform some kind of function that adds the record to the database.

I've noticed in the toolbox that a Command Button control doesn't exist. How is this functionality usually handled? How should I execute the function of adding data instead of pressing a "Command Button"?

Thanks,
