I have a DataGrid where one of the columns has a labelFunction. When I run the application a scrollbar shows up in the DataGrid indicating to me that it has data but there is nothing in the DataGrid. When I scroll items start showing up. When I Debugged it I noticed that the labelFunction was never being called until I started scrolling. Does anyone know why this is happening?

If you are assigning
labelFunctionat a later time using ActionScript after setting thedataProvider, try calling datagrid.invalidateList() or datagrid.updateList() after assigning it - these functions force a refresh of all the rows.
