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();

    }

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.

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();
 
       }
