Class	public class FlexDataGridFooterCell
Inheritance	FlexDataGridFooterCell FlexDataGridCell mx.core.UIComponent

FlexDataGridCell is the container component for each of the DataGrid's cells. This is a psuedo abstract class, the cells that you see in the grid are actually one of the following subclasses of this class:

• FlexDataGridHeaderCell
• FlexDataGridFilterCell
• FlexDataGridFooterCell
• FlexDataGridPagerCell
• FlexDataGridLevelRendererCell
• FlexDataGridExpandCollapseHeaderCell
• FlexDataGridExpandCollapseCell
• FlexDataGridPaddingCell
• FlexDataGridDataCell

There are two other cells types, FlexDataGridDataCell2 and FlexDataGridDataCell3 (if you set enableDataCellOptimization=true) that do not inherit from this class, but are used in lieu of FlexDataGridDataCell in Flex 4 based grids to improve performance, since they are lighter than FlexDataGridDataCell The FlexDataGridCell is responsible for sizing, positioning (based on padding), drawing the background, and drawing the borders. This class has a renderer property, which is the actual component that is displayed on the UI. In case of the Header,Data or Footer cells the default renderer is a UITextField or UIFTETextField. For Filter, it is an instance of the IFilterControl. For the Pager, it is an IPager control. For the LevelRenderer it is an instance of the Class Factory that you specify in the nextLevelRenderer of the associated column Level. For the ExpandCollapse cells, it will draw an instance of the expand collapse icon on basis of the disclosureIcon style property All the drawing happens in the drawCell method. It seperately calls the drawBackground and drawBorder methods. Usually specifying the style properties, or the cellBackgroud/rowBackground/cellBorder/rowBorder functions is sufficient, but in case its needed, these methods can be overridden in a custom implementation, and this custom implementation can then be hooked in via the dataCellRenderer, headerCellRenderer, footerCellRenderer, pagerCellRenderer, filterCellRender, expandCollapseHeaderCellRenderer,nestIndentPaddingCellRenderer, and expandCollapseCellRenderer of the column or the level. Please note, that this class is recycled, so for example, as you scroll, a FlexDataGridCell object that was displaying some other item in the data provider previously could be reused to display the current one.
