RE: [flexcoders] DataGrid With CheckBox ItemRenderer

[Alex Harui]

Hard to tell from that code.  Are you working from an example on my blog 
(blogs.adobe.com/aharui) or FlexExamples?

Subject: [flexcoders] DataGrid With CheckBox ItemRenderer


Hi

I'm hoping this is simple and I have done something silly.

I have a datagrid with an itemrenderer which is a CheckBox and I
have written the code below to deal with it. You will see some
references to custom events that I have written as well.

When I use it, the datagrid no longer updates on rollover and I
can't work out why. All that happens is it highlights the first row
you rollover and then stops.

Any ideas anyone ?

Thanks

Chris
