Question

I’m just learning to program…I have a dropdownlist like this.

<div>
    <asp:DropDownList ID="DropDownList1" runat="server">
    <asp:ListItem >Alabama</asp:ListItem>
<asp:ListItem >Alaska</asp:ListItem>
    </asp:DropDownList></div>

Using C# I want to send the selected item to database. Database field is County nvarchar(50) NULL,

I saw some example in C# backend .I found this one on the internet.Can i send above selected item from below coding ?

protected void Page_Load(object sender, EventArgs e)
   {

       ListItem[] items = new ListItem[3];
       items[0] = new ListItem("One", "1");
       items[1] = new ListItem("Two", "2");
       items[2] = new ListItem("Three", "3");

       DropDownList1.Items.AddRange(items);

Answer 1

  List<ListItem> items = new List<ListItem>();
  items.Add(new ListItem("Alabama", "Alabama"));
  items.Add(new ListItem("Alaska", "Alaska"));
  DropDownList1.Items.AddRange(items.ToArray());

if you want to get selected items from DropDownList1

var selectedText = DropDownList1.SelectedItem.Text;

var selectedValue = DropDownList1.SelectedItem.Value; 

if you need to insert this value to database then

using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlCommand command = connection.CreateCommand())
{
    command.CommandText = "INSERT INTO tableName (County) VALUES (@County)";

    command.Parameters.AddWithValue("@County", selectedText);

    connection.Open();
    command.ExecuteNonQuery();
}
