using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
SqlConnection cn;
SqlDataAdapter da;
protected void Page_Load(object sender, EventArgs e)
{
cn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=E:\C#\WebSites\Order By\App_Data\Database.mdf;Integrated Security=True;User Instance=True");
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (DropDownList1.SelectedItem.Text == "Ascending")
{
da = new SqlDataAdapter("Select* from Product order by Name ASC", cn);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
}
else
{
da = new SqlDataAdapter("Select* from Product order by Name DESC", cn);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
}
}
}
