How to add new rows to the top in datagrid view

Question

I have a DataGridView in which Im adding row values in runtime. Each new row is added below the previous row. I want to add newest row on top. When a new row is added I want the previous row to be below the new one.

I also need some help in deleting the oldest row once the row count reaches 100, so that my DGV will always have 100 rows no matter how many rows I add. I tried this by doing this, but it always gives me an index out of range error:

            if (dataGridView4.Rows.Count >= 99)
            {
                dataGridView4.Rows.RemoveAt(0); //also tried 98
            }

Answer 1

you can bind your DataGridView with source collection .Try adding new item by inserting item in source such as this code

datalist.Insert(0, item)
