Hi Mohan The error says The index is out of range. That means you were trying to index an object with a value that was not valid. If you have two books and I ask you to give me your third book you will look at me funny. This is the computer looking at you funny. You said - create a collection. So it did. But initially the collection is empty: not only is there nothing in it - it has no space to hold anything. It has no hands. It means that you are accessing a location or index which is not present in collection. To find this Make sure your Gridview has 5 columns as you are using it's 5th column by this line dataGridView1.Columns[4].Name = Amount; Here is the image which shows the elements of an array. So if your gridview has less column then the (index + 1) by which you are accessing it then this exception arises.
