How to add an item to a drop down list in ASP.NET?

Question

I want to add the "Add new" at a specific index, but I am not sure of the syntax. I have the following code:

protected void Page_Load(object sender, EventArgs e) {         DRPFill();         if (!IsPostBack)         {             DropDownList1.Items.Add("Add New");         } } public void DRPFill() {     if (!IsPostBack)     {         //Object         AddMajor objMajor = new AddMajor();          //Data Table         DataTable dtMajor = objMajor.find();          //Data Source         DropDownList1.DataSource = dtMajor;         DropDownList1.DataValueField = "MajorID";         DropDownList1.DataTextField = "MajorName";          //Data Bind         DropDownList1.DataBind();     } } 

Answer 1

Try this, it will insert the list item at index 0;

DropDownList1.Items.Insert(0, new ListItem("Add New", "")); 

Answer 2

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">      <asp:ListItem Text="Add New" Value="0" /> </asp:DropDownList> 

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );  DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);
