hi, it a generic error you will get when refer a wrong index i.e index which is not available in a collection or arry etc.

i.e suppose if you are having an array with 5 values then the index starts from 0 and ends with 4. the same applies to any collection like grid.Rows or array of objects etc.,

you will get System.ArgumentOutOfRangeException error when you refer index < 0 or > 4 of collection which has only 5 items.
