You can validate data by handling the Cell Validating event, which is raised by the Data Grid View when the current cell changes.

In this walkthrough, you will retrieve rows from the column and tries to leave the cell, the Cell Validating event handler will examine new company name string to make sure it is not empty; if the new value is an empty string, the Data Grid View will prevent the user's cursor from leaving the cell until a non-empty string is entered.

For example, you can make data entry more efficient by providing default values for new rows and by alerting users when errors occur.
