Hi Alex,
I tried to use invalidateList() but it didn't worked out, I also tried
out calling updateList() but it was also giving error when i change the
fontsize again and again. finally i registered a upadateComplete event and
wrote following and it worked.
private function updateCompleteHandler(event:FlexEvent):void{
while(rowInfo.length > listItems.length){
rowInfo.pop();
}
}
I don't know if this is correct or not but it is working for me.

Try calling invalidateList( ) (not
invalidateDisplayLi st()) after you change the font size

Getting error when change RowHeight and then Scroll Datagrid
Hi All,
I have a datagrid in which rowheight depends upon the
fontSize. If i increase the fontSize rowheight increases and if i decrease the
font size rowheight decreases. but at runtime when i change the fontsize , and
scroll the grid i get error.I observed that when rowheight changes rowInfo is
not updated like listItems.
At this time
rowInfo = 14
listItems = 10
TypeError: Error #1010: A term is undefined and has no properties.
