Flex wouldn't let me. I did an inline renderer:
<datagrid....
<datacolumn blah blah blah...
<component...
<itemrenderer>
<checkbox change="processmychange()"...
</checkbox>
</itemrenderer>
</component>
</datacolumn>
</datagrid>
Flex said it couldn't find processmychange(). However, when I put the
change="processmychange()" inside the datagrid declaration, it found
it okay.
