DropDownList initial value

[AT76]

Hi,

I'm working on a web app that displays a couple of dropdownlists (ddl feed from an xml doc). When the app starts the 2 dropdown lists contain the 1st item of their respective lists. What I would like to do is have these values empty until the user makes a selection.

Depending on what the user selects for the first dropdownlist should dictate what options are available on the 2nd dropdownlist when clicked.

Here's my code:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.Xml.XPath;
using System.Xml.Xsl;
using System.IO;
using System.Text;

public partial class _Default : System.Web.UI.Page 
{
    private string xmlPath;


    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack) 
            {
                FillDropDown();
                FillDropDown2();
            }
    }

    private void FillDropDown()
    {
        this.selection.Items.Clear();
        XmlDocument xDoc = new XmlDocument();
        xDoc.Load(xmlPath);
        XmlNodeList audienceList = xDoc.SelectNodes("/dataroot/List[not(Name=preceding-sibling::List/Name)]/Name");

        foreach (XmlNode n in audienceList)
        {
            ListItem item = new ListItem(n.InnerText, n.InnerText);
            this.selection.Items.Add(item);
        }
    }

    private void FillDropDown2()
    {
        this.selection2.Items.Clear();
        XmlDocument xDoc = new XmlDocument();
        xDoc.Load(xmlPath);
        XmlNodeList audienceList = xDoc.SelectNodes("/dataroot/List[not(Job=preceding-sibling::List/Job)]/Job");

        foreach (XmlNode n in audienceList)
        {
            ListItem item = new ListItem(n.InnerText, n.InnerText);
            this.selection2.Items.Add(item);
        }
    }
}

I would greatly appreciate it if someone can point out how to start the app with empty dropdownlists values. Thank you!

The easiest method will be to insert a default value e.g.

   MyDropDownList.Items.Insert(0,"Select From List...")
