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.

Saves the value in the editor to the data provider of the item renderer's owner. This method updates the data provider element corresponding to the row of the edited cell. This function calls GridItemEditor.validate() to verify the data may be saved. If the data is not valid, then the data is not saved and the editor is not closed.

Do not call this method directly. It should only be called by the control hosting the item editor. To save and close the editor, call the endItemEditorSession() method of the item renderer owner.

Zwraca

Boolean — true if the save operation succeeded, and false if not.
