Windows Form Application DataGridView Operations

// Adding data to datatable
DataRow dr = dt.NewRow();
dr["ID"] = 1;
dr["token_no"] = "Amit";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["ID"] = 2;
dr["token_no"] = "Ajit";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["ID"] = 3;
dr["token_no"] = "Rahul";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["ID"] = 4;
dr["token_no"] = "Sanjay";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["ID"] = 5;
dr["token_no"] = "Zuber";
dt.Rows.Add(dr);
dt.AcceptChanges();
}

private void Form1_Load(object sender, EventArgs e)
{

//Bind the datagridview with datatable
dataGridView1.DataSource = dt;
}

/// <summary>
/// Header click event handler that perform the sorting on DataGridView
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void dataGridView1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
if (cntr % 2 == 0) //This condition applied for toggeling the Ascending and Descending sort
dataGridView1.Sort(dataGridView1.Columns[e.ColumnIndex], ListSortDirection.Ascending);
else
dataGridView1.Sort(dataGridView1.Columns[e.ColumnIndex], ListSortDirection.Descending);
cntr++;
}
}
