i've modified my example to give me what i'm trying to achieve but
its very ugly.
[btw. i'm trying this approach because i should be able to do more
sophisticated validations (asynchronous ones)..... without losing
focus from the existing cell.]
public function validateMe(event:DataGridEvent):void
{
var newData:String= TextInput(myGrid.itemEditorInstance).text;
if(newData == "")
{
TextInput(myGrid.itemEditorInstance).errorString = "ERROR";
}
else
{
// update dataprovider
var record:Object=IList(myGrid.dataProvider).getItemAt(e.rowIndex);
record[e.dataField] = TextInput(myGrid.itemEditorInstance).text;
IList(myGrid.dataProvider).setItemAt(record, e.rowIndex);
//destroy editor and setfocus to next cell
myGrid.destroyItemEditor();
myGrid.editedItemPosition = {columnIndex:e.columnIndex+1,
rowIndex:e.rowIndex};
}
}
