    Cell Types
    In This Topic

    There are several different types of cells that can be set in a sheet to customize how the user interacts with the information in that cell. You can specify the cell type for individual cells, columns, rows, a range of cells, or an entire sheet. For each cell type there are properties of a cell that can be set. In general, working with cell types includes defining the cell type, setting the properties, and applying that cell type to cells.

    List of Cell Types

    In general the cell types are grouped into two broad categories: editable cell types (such as text, currency, and number) and graphical or control cell types (such as button, progress, and slider). For a list of cell types and details about using them, refer to Cell Types.

    Header Cells

    While you can assign a cell type to the cells in the row header or column header, the cell type is only used for painting purposes. It is rare that you would set the cell types of header cells.

    Details

    In Spread, a cell has both an editor, which determines how the user interacts with the value in the cell, a formatter, which determines how the value is displayed, and a renderer which does the painting of the cell. The editor is an actual control instance that Spread creates and places in the location of the cell when you go into edit mode. The formatter decides how the displayed text appears. The renderer is simply code that paints that control inside the cell rectangle when the editor is not there.
