You can add a text description for any valid cell in a data grid. For example, you might want to add a description for a cell’s currency information, such as Entity Currency or Parent Currency. After you add cell text, you can make changes to the text.
You can set a size limit for cell text in an application. The default cell text setting is a maximum of 8,000 bytes. You set the maximum size in the AppSettings attribute for the application metadata.
After you add cell text, a blue border is displayed to indicate that there is text associated with the cell.
