DataGridView1.Rows.Add(new string[] { "Mary", "Watson" });

DataGridView1.Rows.Add(new string[] { "Eddie", "Brock" });

}

private void Button1_Click(object sender, EventArgs e)

{

if (RadioButton1.Checked == true)

{

DataGridView1.Sort(new RowComparer(SortOrder.Ascending));

}

else if (RadioButton2.Checked == true)

{

DataGridView1.Sort(new RowComparer(SortOrder.Descending));

}

}

private class RowComparer : System.Collections.IComparer

{

private static int sortOrderModifier = 1;

public RowComparer(SortOrder sortOrder)

{

if (sortOrder == SortOrder.Descending)

{

sortOrderModifier = -1;

}

else if (sortOrder == SortOrder.Ascending)

{

sortOrderModifier = 1;

}

}

public int Compare(object x, object y)

{

DataGridViewRow DataGridViewRow1 = (DataGridViewRow)x;

DataGridViewRow DataGridViewRow2 = (DataGridViewRow)y;

// Try to sort based on the Last Name column.

int CompareResult = System.String.Compare(

DataGridViewRow1.Cells[1].Value.ToString(),

DataGridViewRow2.Cells[1].Value.ToString());

// If the Last Names are equal, sort based on the First Name.

if (CompareResult == 0)

{

CompareResult = System.String.Compare(

DataGridViewRow1.Cells[0].Value.ToString(),

DataGridViewRow2.Cells[0].Value.ToString());

}

return CompareResult * sortOrderModifier;

}

}

}
