Flex : Detect "tab" key press from the last cell of a DataGrid
In a Datagrid, how to detect开发者_C百科 when the user press the key "Tab" from the last cell ? With KEY_DOWN event the selected cell is unknown, with FOCUS_OUT we don't know the key pressed.
Thanks in advance
You can extend a DataGrid like this, a handle the KeyboardEvent.KEY_DOWN
event
public class CustomRowColorDataGrid extends DataGrid
{
public function CustomRowColorDataGrid()
{
super();
this.addEventListener(KeyboardEvent.KEY_DOWN,keyDownHandler);
}
private function keyDownHandler(e:KeyboardEvent) : void
{
trace("onKeyDown:" + e.keyCode) ;
//TAB is 9
if(e.keyCode == 9)
{
// your logic here
}
}
Or you could also declare a regular Flex grid and follow the same idea
<mx:DataGrid id="yourGrid" keyDown="keyDownHandler(event)">
</mxDataGrid>
<fx:Script>
private function keyDownHandler(e:KeyboardEvent) : void
{
trace("onKeyDown:" + e.keyCode) ;
//TAB is 9
if(e.keyCode == 9)
{
// your logic here
}
}
</fx:Script>
