Here's what I've done in the past...
// add this in your init code...
myDataGrid.addEventListener(ListEvent.ITEM_EDIT_END, editEnd);
private function editEnd(evt:DataGridEvent):void{
// get a reference to the datagrid
var grid:DataGrid = evt.target as DataGrid;
// get a reference to the name of the property in the
// underlying object corresponding to the cell that's being edited
var field:String = evt.dataField;
// get a reference to the row number (the index in the
// dataprovider of the row that's being edited)
var row:Number = Number(evt.rowIndex);
// get a reference to the column number of
// the cell that's being edited
var col:int = evt.columnIndex;
if (grid != null){
var oldValue:String = String(grid.dataProvider.getItemAt(row)[field]);
var newValue:String =
String(grid.itemEditorInstance[grid.columns[col].editorDataField]);
var rowData:XML = XML(grid.dataProvider.getItemAt(row)[0]);
// check if the value has changed
if (newValue == oldValue){
// nothing has changed...
return;
}
// something has changed...
// do something...
// you could prevent the change if you want
// or do some validation
// or just return and the data move on to the dp.
}
