Thanks for reply. However this does suffice my requirement. my requiremnt is to get rowIndex in mouseover Function in DataGird so that I can use that index to select perticuler row of datagrid.ItemRollover Function does not get called when I hold left mouse key and drag it over dg.
I want to provide functionality where in user can select multiple rows in dg by holding left mouse key and dragging over the dg. I have also designed a sample app for this but Only issue with approach is that It(mOver.target.listData.rowIndex) does not consistently return rowIndex ,sometimes It throws error ‘Property listData not found on mx.controls.listClasses.ListBaseContentHolder and there is no default value” as a result of it ,few row left unselected. This error occurs only when user tries to select rows with fast mouse movement.
