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, Eve         


        

Answer 1

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);

Answer 2

Try following code;

DropDownList1.Items.Add(new ListItem(txt_box1.Text));

Answer 3

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

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