DropDownList problem


V

Viktor Popov

Hi,

I use a DropDownList for presenting information from DataBase. Here it is
the code:

private void Page_Load(object sender, System.EventArgs e)
{
if(!Page.IsPostBack)
{
SqlConnection conn = new SqlConnection("Data Source=BLEK;Initial
Catalog=Estate; User [email protected]@@; [email protected]@@@@");
SqlDataAdapter dad1 = new SqlDataAdapter ("SELECT o.OfferID,o.TypeOffer FROM
blek.TypeOffer o ORDER BY o.TypeOffer", conn);
DataSet ds =new DataSet();
conn.Open();
dad1.SelectCommand.ExecuteNonQuery();
dad1.Fill(ds,"Offers");
DDL1.DataSource=ds.Tables[0];
DDL1.DataValueField = "OfferID";
DDL1.DataTextField = "TypeOffer";
DDL1.DataBind();
conn.Close();
}
}

The problem is that when I like to Search by letter in the DropDownList
DDL1 it doesn't work. How could be enabled this feature?
Thank you!

Hi Viktor,

I think that you asked this before, and I asked back to what do you
understand by "search by letter" ?
You never answered that.

Thank you for the replies.
Search by letter for me means when in the DropDown list is information like
this:
Alabama
Argentina
Atlanta
and the user types "A" the selection goes to Alabama.Than when he/she types
"R" the selection goes to Argentina.
Thank you !

Viktor

Hi,

There is no control that does that, you have to implement it in javascript,
I did it a LONG time ago but I have no idea where to find it now.
if you search in a javascript NG I'm sure you will find some examples.

cheers,
