RE: [flexcoders] Help !!! Getting error when change RowHeight and then Scroll Datagrid
Yeah, I thought invalidateList would clean that up for you. Somehow,
rowInfo gets out of sync with listItems and things get messed up..

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

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
