How to download a file through dropdownlist using asp.net

[Aviplo]

Hi

Can any one tell my how can i download a file from MySql through dropdownlist

What i'm trying to do is i created a dropdownlist and shows all the file name in that dropdownlist now i want user to be able to download that file when they select any item on the list. Once they click on any item on the list it should popup a download window that they can click on SaveAs button to download that file.

I have saved only a link in the database and the actual file is saved in a folder i created

please help!!

thanks.

This is straight coding, enable the dropdown list autopostback property true, capture its onselectedindex change event. if you save the file name and path in db, your dropdown value should be "Path" and text should be "file name". And to download the file see following link:

Or google more, you will find plenty of links.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {

        Response.Redirect("../meeting/"+ DropDownList1.SelectedItem.Value  );


    }

now i have a problem with the dropdownlist selectedindexchanged event is fire only the 0th index no mather in what index i clicked on
so here comes the code

    private void loadData()
    {

        DataTable DT = new DataTable();
        OdbcCommand cmd;
        OdbcConnection conn = new OdbcConnection(constr);
        if (conn.State == ConnectionState.Closed)
        {
            conn.Open();
            OdbcCommand sql = new OdbcCommand("SET CHARACTER SET `tis620`", conn);
            sql.ExecuteNonQuery();
            sql.Dispose();
        }

        cmd = new OdbcCommand("SELECT ifnull( filename, '' ) AS filename,name FROM `abt_meeting_topic` left join  abt_meeting on abt_meeting.aid = abt_meeting_topic.id   ", conn);

        try
        {
            OdbcDataReader dReader = cmd.ExecuteReader();

            {
                DropDownList1.DataSource = dReader;
                DropDownList1.DataTextField = "name";
                DropDownList1.DataValueField = "filename";
                DropDownList1.DataBind();
                dReader.Close();

            }
        }
        catch (Exception ex)
        {
           Response.Write(Utility.MessageBox("ไม่สามารถเรียกข้อมูลได้ กรุณาแจ้งผู้ดูแลระบบ (Error : " + ex + ")"));
        }
        if (conn.State == ConnectionState.Open)
        { conn.Close(); conn.Dispose(); }
    }

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {

            Response.Write("../meeting/" + DropDownList1.SelectedItem.Text);

    }

every comment appreciated.

• Correct the above code

Actually I used Response.Redirect instead of Response.Write

 protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
        {

                Response.Redirect("../meeting/" + DropDownList1.SelectedItem.Text);

        }
