I'm working on a Flash Forms Application using MM 2004 MX Professional. I'll
be pulling the data from a web service I wrote (got that working fine). One of
the things I need is to sort a column of "numbers" (passed from my ws as
strings actually) in a special order so that the first is 5, next is 15, then
4, then 14... It all makes sense to me trust me.
To do this I've created a global array called starV so that starV[5] = 0,
starV[15] = 1, etc. To use this when sorting my grid I trap headerRelease and
then use sortOnItems to call my function. Trouble is I can't figure out how to
refer to my function. I've attached some sample code; to play with it you'll
need to create a new Flash Forms Application file. I renamed the default
"form1" to "gridView" but I don't think that matters. Then drag a dataGrid
onto the stage and name it "Cars_dg". The code sets sizes and supplies it.
Clicking the two "stars" columns should invoke my code.
Note that I can do this easily in a more normal "Flash Document", just not in
the Forms Application.
Thanks for ideas and help.
