Seems odd that you'd be setting rowHeight inside updateDisplayList. You should probably do it on the event where the user selects the option. You shouldn't need callLater either, the DG should respond on the next update. It might be easier to figure out once try to get it working that way. -Alex

Hi Alex, I have done following: In the class where i added my datagrid as child: override protected function updateDisplayList(){ ... // This height needs to be set at runtime, if user selects an option // I have to increase the rowheight. if(changeHeight){ myDataGrid.rowHeight = 50; }else{ myDataGrid.rowHeight = 30; } doSomething(); callLater(validateMyDataGrid); } private function validateMyDataGrid():void{ myDataGrid.validateNow(); } I tried putting invalidateDisplayList() and other functions but didn't worked.

Increasing rowHeight while scrolling would probably not be handled correctly. Increasing rowHeight and scrolling before system validated the DataGrid may not be handled well either. Might you be doing one or the other? ________________________________ From: flexcomponents@ yahoogroups. com [mailto: flexcomponents@ yahoogroups. com ] On Behalf Of arpan srivastava Sent: Saturday, March 24, 2007 3:36 AM To: Flex Components Subject: [flexcomponents] error when increase the rowheight at runtime? Hi All, I need to change rowheight of my datagrid at runtime. I have a bar chart in one of my columns and when i change a property of bar chart at runtime the row height of the datagrid should change. I am able to change the rowheight but when i scroll the datagrid just after changing the property i get an error from "scrollVertically( )" function in "ListBase.as" that some property is undefine or null. I am not getting at all what is the cause of the error. Is it just increasing the height of row at runtime or anything else? Thanks Arpan ________________________________ The fish are biting.
