How to display List items in Listview?

Question

I have a ListView in my aspx file like this:

<asp:ListView ID="ListView1" runat="server"></asp:ListView>

and then I have List like this:

List<string> mylist = new List<string>();

Im trying to populate the ListView like so:

foreach(string elem in mylist)
{
  ListView1.Items.Add(new ListViewItem(elem));
}

But my compiler is telling me best overload match error & cannot convert string to ListViewItem. This is a asp.net 4.0 web app. Any suggestions?

Answer 1

Try binding your ListView like the following:

code-behind

List<string> mylist = new List<string>() { "stealthy", "ninja", "panda"};
listView.DataSource = mylist;
listView.DataBind();

aspx

<asp:ListView ID="listView" runat="server">
    <ItemTemplate>
        <asp:Label Text="<%#Container.DataItem %>" runat="server" />
    </ItemTemplate>
</asp:ListView>

Answer 2

With a ListView, you should be able to bind the data to the DataSource of the control:

ListView1.DataSource = myList;
ListView1.DataBind();

Answer 3

ListViewItem does not have any constructor that takes a string. Also ListView.Items is an IList<ListViewDataItem> not a collection of ListViewItem

You probably want to use databinding rather than iteratively adding items anyway.
