sort data in datagrid view in windows forms in C# .net

private void Sort_DataGrid(object source, System.Web.UI.WebControls.DataGridSortCommandEventArgs e)

{

    // Never use Queries like this always use Stored procedures

    SqlCommand myCommand = new SqlCommand("SELECT * FROM Categories", myConnection);

    myCommand.CommandType = CommandType.Text;

    SqlDataAdapter myAdapter = new SqlDataAdapter(myCommand);

    DataSet ds = new DataSet();

    myAdapter.Fill(ds, "Categories");

    DataView dv = new DataView(ds.Tables["Categories"]);

    if ((numberDiv % 2) == 0)

        dv.Sort = e.SortExpression + " " + "ASC";

    else

        dv.Sort = e.SortExpression + " " + "DESC";

    numberDiv++;

    myDataGrid.DataSource = dv;

    myDataGrid.DataBind();

}

Here i wrote the code in Sort_Grid event now what you can do is you can create a combobox event and you can do the same operation based on you selection from combo.

For more info you can refer to this article by mahesh:
