You can use ddlitems.SelectedItem.Text or ddlitems.SelectedItem.Value to get the selected value from the dropdown list. Try Once..!!

Check that you have call ddlbind() method in page load in
if(!isPostback)
{ddlbind();}

Try this code, I think when you are select drop down list your page is redirect, when page is redirect again fill the values in drop down list.
I hope this will be help you.

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            ddlbind();
        }

    }
    public void ddlbind()
    {
        BALBillDetails B = new BALBillDetails();
        DataSet ds = B.GetItemNames();
        ddlitems.DataSource = ds.Tables[0];
        ddlitems.DataTextField = "Item_Name";
        ddlitems.DataValueField = "Item_Code";
        ddlitems.DataBind();

    }

The Dropdown sholud be binded in the following manner if you are connecting to the database using ADO.NET.

C#

public void ddlbind()
       {
           BALBillDetails B = new BALBillDetails();
           DataSet ds = B.GetItemNames();
           ddlitems.DataSource = ds.Tables[0];
           ddlitems.DataTextField = "Item_Name";
           ddlitems.DataValueField = "Item_Code";
           ddlitems.DataBind();
 
       }

Hi Your Error is on ddlitems.DataSource = B.GetItemNames();
check what return it.or
you can Try it too:
1.Click on top right of dropdown -Choose Data source.
2.Select New Data Source.
3.Select Object.
4.Select your BLL class.
5.Configure setting.
Yours Farhad.
