Dropwdown list in IE when using tab

[user1980]

Hello there

I have a webform which has a dropdown list with the countries names in it. The dropdown list does a autopostback. When I try to fill the form using tab key to move from one controller to other, the dropdown list gives a problem.
In IE, if I have to select USA, when I tab down to the dropdown list and press U, the first country with U ie Uganda get selected automatically and focus jumps to next control. In firefox this works perfectly. can somebody help me with this..thank you...

First of all clear the AutoPostBack field of DropDownList and make the AutoPostBack of Page_Load() also not true. I hope it'll work fine. I made a simple application following the same rule and tab works fine giving no problem.

public class Country
{
    private string name;
    public string Name
    {
        get { return name; }
        set { name = value; }
    }
    public Country(string name)
    {
        Name = name;
    }
    public Country()
    {
        //
        // TODO: Add constructor logic here
        //
    }
    public static List<Country> GetCountry()
    {
        List<Country> country = new List<Country>();
        country.Add(new Country("India"));
        country.Add(new Country("USA"));
        country.Add(new Country("England"));
        country.Add(new Country("China"));
        country.Add(new Country("bangladesh"));
        country.Add(new Country("Pakistan"));
        country.Add(new Country("France"));
        return country;
    }
}

public partial class _Default : System.Web.UI.Page 
{
    private List<Country> country = Country.GetCountry();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DropDownList1.DataSource = country;
            DropDownList1.DataTextField = "Name";
            DropDownList1.DataValueField = "Name";
            DropDownList1.DataTextFormatString = "Name: {0}";
            DropDownList1.DataBind();
        }
 
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = DropDownList1.SelectedValue;
    }
}
 

In my page I dragged a DropDownList, a button and a Label. While tabbing, it comes first on DropDownList, second on Button, prssing enter it gives the selected country's name in Label.

Best of Luck.

Thank you for the reply. But I would need to do a post back so that another dropdown populates depending on the selection of the country ddl. so in this case how would I achieve it.

thank you once again for your time.

Have you considered handling the JavaScript onblur event for the DropDownList and manually doing a postback to the server?

Besides trying what Frinavale has said, if I use .NET 3.5, then I'd try LinkDatSource as a common data access layer between these two controls.
