    <p>Ok guy, i have made a simple program that has a web form where you fill in details fruit name, kg and cal count. i have then used session variables to get the fruit name from the form on default page and display them on about page in a drop down menu. that's all working fine, what i cant seem to work out is on the about page how to get it so the user selects a item from the drop down (created from form on default page) then enter a int how many they want (in text box) and have there selection and amount output on a list box on about page. il post the code i have so far any help would be much appreciated.</p> <p><strong>default page</strong></p> <pre><code> public class Fruit { private string fName; private int grams, calsPerGram; private bool edible; public Fruit(string n, int g, int c, bool e) { grams = g; calsPerGram = c; edible = e; fName = n; } public int totalCalories() { return grams * calsPerGram; } public string getFruitInfo() { string s; if (edible == true) { s = fName + " is yummy and it has " + totalCalories() + "calories"; } else { s = "Hands off! Not edible"; } return s; } } public partial class _Default : System.Web.UI.Page { List&lt;Fruit&gt; myBasket; protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { myBasket = new List&lt;Fruit&gt;(); Session["listSession"] = myBasket;// seassion start } } protected void Button1_Click1(object sender, EventArgs e) { // Session["Fruitname"] = TbxName.Text; // my session i have made MyFruit = Session["Fruitname"] as List&lt;string&gt;; //Create new, if null if (MyFruit == null) MyFruit = new List&lt;string&gt;(); MyFruit.Add(TbxName.Text); Session["Fruitname"] = MyFruit; abc.Items.Clear(); Fruit f = new Fruit(TbxName.Text, int.Parse(TbxWeight.Text), int.Parse(TbxCal.Text), CheckBox1.Checked); myBasket = (List&lt;Fruit&gt;)Session["listSession"]; // session used myBasket.Add(f); foreach (var item in myBasket) { abc.Items.Add(item.getFruitInfo()); // List box used } } public List&lt;string&gt; MyFruit { get; set; } } </code></pre> <p><strong>About page</strong></p> <pre><code>public partial class About : Page { protected void Page_Load(object sender, EventArgs e) { MyFruit = Session["Fruitname"] as List&lt;string&gt;; //Create new, if null if (MyFruit == null) MyFruit = new List&lt;string&gt;(); DropDownList1.DataSource = MyFruit; DropDownList1.DataBind(); } protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { Drinklabel.Text = "Your Chosen Beverage is A " + DropDownList1.SelectedValue.ToString() + " Drink."; } public List&lt;string&gt; MyFruit { get; set; } } </code></pre>

    1. COWhy do you want a drop down list selection and text box value put into a `ListItem`? Wouldn't you want these values in a label, like "User has wants x number of fruit Y."?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
