Odd behavior in ArrayCollection

MX Datagrid horizontal scroll column into view

Hi, I'm trying to figure out how to programmatically scroll an MxDatagrid column into view. i.e: if I update a cell, I'd like to make sure it's in view (actually I just need the column in view) I've done this before, so I know it's doable. Thanks Dave -- View this message in context: htt

Re: Databinding with SparkGrid and locked headers/columns seems broken

Replaced Spark Datagrid with Mx Datagrid, left everything else the same, and data binding problems disappeared. So, I'm convinced that Spark Datagrid has issues with databinding. These definitely seem broken: 1) Cells in locked columns don't always update, both in the case when a whole dataitem

Databinding with SparkGrid and locked headers/columns seems broken

Thanks Evyatar, below is the code I'm going to use. The problem of the 'moving GridItemRenderer' remains. That is: the effect starts on one cell of the data grid, but if you scroll the data grid such that that GridItemRenderer is recycled, then the effect continues to play out on the same gridIte

Re: Flex Datagrid: MX vs Spark

Thanks, the reason for putting it on the layout is because useVirtualLayout is not exposed as a public property on Spark Datagrid. Your answer explains why I didn't see any performance difference, however, isn't it still a bug for a layout not not respect height="100%" when useVirtualLayout='true'

Re: Best way to blink a Spark Datagrid cell

Piotr - the problem is with turning off the blinking after some period, because at that later time, the renderer may be showing data belonging to a DIFFERENT cell. e.g. if you scroll the datagrid, the renderer will be recycled and will now be attached to a completely different cell. Alternativel

The Spark Datagrid seems to use a canvas to scroll and is much, much, more responsive that the MX Datagrid. I wish there was more documentation on this, I suspect that in 4.13 you probably shouldn't be using ANY mx components (i.e: I'm guessing that if the Spark Datagrid component has exceeded the
