Runtime Versions:

Flash Player 10, AIR 2.5

The IGridItemEditor interface defines the interface that item editors for the Spark DataGrid and Spark Grid controls must implement. The DataGrid and Grid controls are referred to as the item renderer owner, or as the host component of the item editor.

All of the item editor's properties are set by the owner during the start of the editor session. The data property is the last property set. When the data property is set, an item editor should set the value of the editor's controls. Next, the editor's prepare() method is called. IGridItemEditor implementations should override the prepare() method to make any final adjustments to its properties or any aspect of its visual elements. When the editor is closing, the discard() method is called.

When the editor is closed, the input value can be saved or canceled. If saving, the save() function is called by the editor to write new values to the data provider element corresponding to the row of the edited cell.
