DropDownList中的ASP.NET 2 DataValuefield

Question

I am having a problem in ASP.NET. I have a table names Articles with these columns in Database:

Column 1:

Column 2:

Column 3:

I have a dropdownlist like this DropDownList1.DataTextField = "PERSHKRIM";

What I want to do is when I choose a product from DropDownList for example if I choose dropuct aa in a Label it will show PROD1 from Column 2 and in a second label it will show 111 from Column 3.

My code is this:

DataTable listaArtikujt = new DataTable();

using (SqlConnection lidhje = new SqlConnection(ConfigurationManager.ConnectionStrings["DEN1ConnectionString"].ConnectionString))
{
    try
    {
        SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM [Articles]", lidhje);
        adapter.Fill(listaArtikujt);
        DropDownList1.DataSource = listaArtikujt;
        DropDownList1.DataTextField = "PERSHKRIM";
        DropDownList1.DataValueField = "KOD";
        DropDownList1.DataBind();
        Label1.Text = DropDownList1.SelectedValue.ToString();
    }
    catch (Exception ex)
    {
        Response.Write("Error:" + ex.ToString());
    }
}

NOTE again: These columns are in one table names Articles .

Answer 1

I guess, this is what you are looking for:

        SqlDataAdapter adapter = new SqlDataAdapter("SELECT PERSHKRIM, KOD + '~' + CMSH AS KC FROM [Articles]", lidhje);
        adapter.Fill(listaArtikujt);
        DropDownList1.DataSource = listaArtikujt;
        DropDownList1.DataTextField = "PERSHKRIM";
        DropDownList1.DataValueField = "KC";
        DropDownList1.DataBind();
        Label1.Text = DropDownList1.SelectedValue.Split('~')[0].ToString();
        Label2.Text = DropDownList1.SelectedValue.Split('~')[1].ToString();

Note: if there will be '~' char in your records, it will cause problems. Choose most appropriate char according to your records.
