[flexcoders] Re: Footer row with a DataGrid
I also looked at Alex's code and decided I wanted something a little more suited to my peculiar needs. I implemented a custom control which has two data grids, one for the data and one for the totals at the bottom. I also added some fancy code to cope with making totals in different ways (e.g. aggregating averages - the old sum(x)/n vs sum(x/n) problem) and to handle formatting. It is not as clean an interface as I would like, but it is pretty useful and it now appears in lots of places in my UI. There is a known bug where the column widths are misaligned when trhe control first shows, but my users seems to be able to live with that. If you contact me at simon.palmer @ gmail.com I'll send you some code and you can perhaps adopt it for your own needs. If I could figure out a host who would allow swf's I'd post it on my blog. --- In flexcoders@yahoogroups.com, Guy Morton [EMAIL PROTECTED] wrote: Hi people What is the best way to achieve a footer row in a DataGrid? I want to be able to set the values in the footer row myself, ie I don't need it to do any fancy calculations. I found this: http://blogs.adobe.com/aharui/2008/03/flex_3_datagrid_footers.html Does anyone have a better idea as to how to proceed? TIA Guy

Given that no-one has suggested an alternative, I think the answer to that might be No. It is possible of having a datagrid for the footer information under the one of the data table. It's simpler to handle but the behavior is not as smooth as in Alex's demo. The columns of the footer DG get aligned only after you have dropped the column bar into its new position. mx:Script ![CDATA[ private function onColumnStretch(event:DataGridEvent):void { DataGridColumn(summaryDG.columns[event.columnIndex]).width = DataGridColumn(dataDG.columns[event.columnIndex]).width; } // You may also need to run this on container resize public function alignColumns():void { for(var i:uint = 0; i dataDG.columns.length; i++) { DataGridColumn(summaryDG.columns[i]).width = ataGridColumn(dataDG.columns[i]).width; } } ]] /mx:Script mx:DataGrid id=dataDG columnStretch=onColumnStretch(event) width=100% height=100% verticalScrollPolicy=on columns={dgColumns} dataProvider={dgProvider} / mx:DataGrid id=summaryDG showHeaders=false width=100% height=25 columns={sumColumns} dataProvider={sumProvider} /
