You can use the feature-rich set of cell types or extend the functionality by defining your own. Use any of the more than 20 pre-defined cell types or create your own to determine what kind of data can be entered into a cell, avoiding unnecessary checks and validations by the developer, and providing a natural way for your user to enter data.
You can set barcode cell types for displaying barcodes, fractions in cells using the properties added to the number cell type, and allow your users to select a color from a color picker cell.
GcDateTime, GcNumber, and GcTextBox cells are now available in addition to the standard Spread date-time, number, and text cells.
For more information about cell types, refer to Customizing Interaction with Cell Types.
