RE: [flexcoders] DataGrid Weirdness with Online Example
Took a while to reproduce... which may trick you in believing its all ok.

Re: [flexcoders] DataGrid Weirdness with Online Example
iko, thanks for your response. I can't set the editable=false property on the grid columns because then they won't report back selections / deselections to the data provider (an ArrayCollection). Also, your second suggestion of manually setting the selected property is already being done in my custom AS3 renderer in the overriden clickHandler() function. | Aaron West | aaron AT trajiklyhip DOT com | http://www.trajiklyhip.com/blog/ | Certified Advanced Adobe ColdFusion MX 7 Developer | Certified Macromedia FlashMX Developer | Adobe Community Expert On Oct 19, 2006, at 2:09 PM, Iko Knyphausen wrote: Took a while to reproduce... which may trick you in believing its all ok.

RE: [flexcoders] DataGrid Weirdness with Online Example
Yes, I believe you can set editable to false thats what I did, at least. The checkbox is still there as a renderer, and if you react on its change event you can set the underlying datagrid data field to true or false respectively. This should be remembered by the ArrayCollection. BTW, this was not meant as a second alternative suggestion...it was meant in combination with switching of the editable property. Am I making sense ?
