Application-Generated Column Values in DataGridView on New Record

I have a DataGridView which I am using to enter new records to a table with 5 columns/fields. However, values for two of the fields are generated by the program automatically using some algorith (not the database AutoNumber). As such, they should not be entered in the datagrid view. The idea is that when i click a "New Record" button, the corresponding two columns are disabled to disallow and the values generated and inserted in the respective cells. The user can then enter remainder of data.

My problem is how to have the Automatically generated values in the cells. Any hints?

I have realized that there is a VAlue property for each cell.

I am now using it as follows
           string GeneratedVal=SomeFunction();
           dataGridView1.Rows[0].Cells[3].Value = GeneratedVal;

Open in new window

you can also use this for setting a default value for the new row.

        private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
        {
            if (e.RowIndex >= 0)
                dataGridView1.Rows[e.RowIndex].Cells[3].Value = GeneratedVal;
        }

        private void dataGridView1_DefaultValuesNeeded(object sender, DataGridViewRowEventArgs e)
        {
            e.Row.Cells[3].Value = GeneratedVal;
        }
