Error while assigning the data to dataGrid Dataprovided
- by sudeep kumar
Hi , I was trying to acces the datagrid at runtime and want to assign the data to it like
public function getGridData(reportsArray:ArrayCollection):void{
reportData = reportsArray;
trace(" The length of the datagrid is "+reportData.length);
graphDataGrid.dataProvider = reportData;
invalidateDisplayList();
}
but I was getting this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
