I need to calculate the size of a Datagrid at runtime. I have
the number of rows from my dataprovider. So I then need to calc
headerHeight + rowHeight = DGHeight. Reason the DG is in a
component in its own .mxml. So as the dg grows I'll need to expand
its .mxml height a Canvas. It is then a component member of a main
.mxml as <mx:myDGComp width="somesize" height="sizeunknown">.
The effect I'm going for is as the DG grows it causes vertical
scrolling my client saw this on another site and wants it.
