Try calling invalidateList() (not invalidateDisplayList()) 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. at mx.controls.listClasses::ListBase/mx.controls.listClasses:ListBase::scro llVertically()[C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\listClasse s\ListBase.as:5346] at mx.controls::DataGrid/mx.controls:DataGrid::scrollVertically()[C:\dev\fl ex_201_gmc\sdk\frameworks\mx\controls\DataGr! id.as:1923] at mx.controls.listClasses::ListBase/set verticalScrollPosition()[C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\ listClasses\ListBase.as:1043] at mx.controls::DataGrid/mx.controls:DataGrid::scrollHandler()[C:\dev\flex_ 201_gmc\sdk\frameworks\mx\controls\DataGrid.as:1720] at flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchEven tFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\dev\flex_201_gmc\sdk\frameworks\ mx\core\UIComponent.as:8323] at mx.controls.scrollClasses::ScrollBar/h! ttp://www.adobe.com/2006/flex/mx/internal::dispatchScrollEvent()[C:\dev\ flex_201_gmc\sdk\frameworks\mx\controls\scrollClasses\ScrollBar.as:1096 <http://www.adobe.com/2006/flex/mx/internal::dispatchScrollEvent%28%29%5 BC:%5Cdev%5Cflex_201_gmc%5Csdk%5Cframeworks%5Cmx%5Ccontrols%5CscrollClas ses%5CScrollBar.as:1096> ] at mx.controls.scrollClasses::ScrollBar/http://www.adobe.com/2006/flex/mx/i nternal::lineScroll()[C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\scr ollClasses\ScrollBar.as:1058 <http://www.adobe.com/2006/flex/mx/internal::lineScroll%28%29%5BC:%5Cdev %5Cflex_201_gmc%5Csdk%5Cframeworks%5Cmx%5Ccontrols%5CscrollClasses%5CScr ollBar.as:1058> ] at mx.controls.scrollClasses::ScrollBar/mx.controls.scrollClasses:ScrollBar ::downArrow_buttonDownHandler()[C:\dev\flex_201_gmc\sdk\frameworks\mx\co ntrols\scrollClasses\ScrollBar.as:1160] at flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchEven tFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\dev\flex_201_gmc\sdk\fr! ameworks\mx\core\UIComponent.as:8323] at mx.controls::Button/http://www.adobe.com/2006/flex/mx/internal::buttonPr essed()[C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\Button.as:1988 <http://www.adobe.com/2006/flex/mx/internal::buttonPressed%28%29%5BC:%5C dev%5Cflex_201_gmc%5Csdk%5Cframeworks%5Cmx%5Ccontrols%5CButton.as:1988> ] at mx.controls::Button/mx.controls:Button::mouseDownHandler()[C:\dev\flex_2 01_gmc\sdk\frameworks\mx\controls\Button.as:2234] ________________________________ Get the free Yahoo! toolbar <http://us.rd.yahoo.com/evt=48226/*http:/new.toolbar.yahoo.com/toolbar/f eatures/norton/index.php> and rest assured with the added security of spyware protection.
