You just need to modify the datatable that is bound to the datagridview. Something like this should work:

// Setup table with 5 columns
DataTable table = new DataTable();
table.Columns.Add("A", typeof(bool));
table.Columns.Add("B", typeof(bool));
table.Columns.Add("C", typeof(bool));
table.Columns.Add("D", typeof(bool));
table.Columns.Add("E", typeof(bool));

// Add 20 rows
for (int i = 0; i < 20; i++ )
    table.Rows.Add(true, true, true, true, true);

// Rows 10 - 15, set column 5 to true
for (int i = 9; i < 15; i++)
    table.Rows[i].SetField<bool>(4, false);

Note: Column and Row indexes are zero-based so Row 10 is at index 9, Column 5 is at index 4, etc.
