If horizontalScrollPolicy="off" (default), width is not ignored, but attempts are made to proportionally size all columns within the DG. At some point, things degenerate and the proportions are hosed.
If horizontalScrollPolicy="on", width should be honored. Width seems to work in this test, so maybe I don't understand what problem you're running into. <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; width="100 %" height="100 %"> <mx:DataGrid width="100%" height="100%" lockedColumnCount="2" horizontalScrollPolicy="on" variableRowHeight="true"> <mx:columns> <mx:DataGridColumn headerText="Start Date" dataField="TBD" width="200" resizable="false" /> <mx:DataGridColumn headerText="End Date" dataField="TBD" width="50" resizable="false" /> <mx:DataGridColumn headerText="Risk" dataField="TBD" width="50" /> <mx:DataGridColumn headerText="Risk 1" dataField="TBD" width="100" /> <mx:DataGridColumn headerText="Risk 2" dataField="TBD" width="150" /> <mx:DataGridColumn headerText="Risk 3" dataField="TBD" width="200" /> <mx:DataGridColumn headerText="Risk 4" dataField="TBD" width="50" /> <mx:DataGridColumn headerText="Risk 5" dataField="TBD" width="100" /> </mx:columns> </mx:DataGrid> </mx:Application> ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of gers32 Sent: Monday, October 22, 2007 11:25 PM To: [email protected] Subject: [flexcoders] Re: DataGrid: column width and horizontal scroll Yes, width is systematically ignored, that's why I set minWidth, which is better in the sense that the columns are wider (100), but its values are still ignored. Maybe there's an extra parameter (even from a superclass...) I need to set (like I did with horizontalScrollPolicy) for width to be taken into consideration? I forgot to mention I'm using Flex 2.0.1. via the Eclipse Flex Builder 2 plugin.
