Ok so my problem is everytime I click my button it re-populates my dropdownlist of my entries, but it also keeps the entries from my previous page_load therefore i get double entries within my dropdownlist. How do I solve this problem as I cannot seem to find where my problem is:
Code can be seen below:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace PartD
{
public partial class About : Page
{
List<Beverage> account;
string[] arr;
protected void Page_Load(object sender, EventArgs e)
{
arr = (string[])Session["arr"];
for (int i = 0; i < arr.Length; i++)
{
DropDownList1.Items.Add(arr[i].ToString());
}
if (Session["bubble"] == null)
{
account = new List<Beverage>();
Session["bubble"] = account;
}
else
{
account = (List<Beverage>)Session["bubble"];
}
}
protected void Button1_Click(object sender, EventArgs e)
{
ListBox1.Items.Clear(); // clears ListBox1
Beverage f = new Beverage(DropDownList1.Text, int.Parse(TextBox1.Text),
int.Parse(TextBox2.Text), CheckBox1.Checked); // gets text from textbox5, then converts textbox2,textbox3 string to int and will execute of checkbox1 is checked
account = (List<Beverage>)Session["bubble"]; // displays results in listbox1
account.Add(f); // adds items to listbox
foreach (var item in account)
{
ListBox1.Items.Add(item.getFruitInfo());
}
}
}
}
