Link button in data grid

Question

hi
Can anyone tell me why the click action is not working when
the link button is placed in datagrid.
<mx:DataGridColumn dataField="edit" headerText="">
<mx:itemRenderer>
<mx:Component>
<mx:LinkButton label="edit" click = "click1();">
</mx:LinkButton>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
even if button is placed in the datagrid it is not working.

Answer 1

When you use the <mx:Component> tag you create a new
scope. Its as if all of the content of the <mx:Component>
were in another file. If you used a separate file for your renderer
you wouldn't expect click() function to be recognized, right?
You can modify your renderer like this to make it work:
<mx:LinkButton label="edit" click =
"outerDocument.click1();">
Another option is to take advantage of the bubbling feature
of the click event. Instead of putting the click handler on the
LinkButton, put it on the DataGrid itself. Any click on the
DataGrid will then trigger the event handler.
The drawback to that is that EVERY click will call the event
handler - either the LinkButton's click on a click on the header.
Your event handler just has to examine the event data to determine
what control originated the event.
In this case, using outerDocument.click() is far easier, but
you might need the bubbling property of the event at some point in
the future.
