Flex DataGrid sorts

-
Sometimes your data is in a specific order, but not ordered on anything you can really sort by via a data grid. So sometimes you apply a sort with the data grid (or advanced data grid), which is great and everything, but what do you do when you want to reset the data back to the original order?

this.mydatagrid.dataProvider.sort = null;
this.mydatagrid.dataProvider.refresh();

Done!

Flex Advanced Data Grid collapses on refresh

-
I was having this problem with my Advanced Data Grid. Every time the data refreshed the whole thing collapsed, which isn't a good thing when users have drilled down 3 levels. I know this is probably a bad way of doing this, but it is the only way I could get to work. All the examples I've seen of this say to just assign the saved openNodes Object to the openNodes property, like this... myOpenNodes = new Object(); myOpenNodes = IHierarchicalCollectionView(myADG.dataProvider).openNodes //refresh here IHierarchicalCollectionView(myADG.dataProvider).openNodes = myOpenNodes; but that doesn't work!!

Add and remove lineseries - Flex LineChart

-
This took me some time to figure out so I thought I would post about it. Main objective is to toggle on and off lineseries based on user input. Usually this would mean editing the dataprovider, tricky thing here is that I need the color of each line to always be the same based on data, so instead I leave the dataprovider alone and actually add and remove LineSeries to/from the LineChart. This probably isn't the best way to do this, but hey, it works, and it may help someone else out. Here we go... First lets start with the MXML: Here I have a Panel with a LineChart and a Legend inside it, as well as 3 Toggle Buttons. You will notice that there are no series inside the LineChart. <mx:Panel title="LineChart Example" height="500" width="100%" layout="vertical"> <mx:HBox id="choices" horizontalGap="0"> <mx:Button id="Profit" label="Profit" toggle="true" click="upda...
