(Update 03.28.2012 Cleaned up article and verified it  works with Asp.net versions 3.5 and 4.0)

The following ASP.Net article details how to create a ListView, bind it to a Linq query and create a dynamic list of hyperlinks to show on an Asp.net web page in C#. To recreate this, use Visual Studio (VS2008/VS2010/VS 11) and create a default Asp.Net Web Application project all working in the default page setup.

On the screen there will be a button which will cause a refresh to the page when pressed. On that refresh the ListView will be cleared of all data and the button disabled to show that the control has not been rebound to actual data.

Here is what it will look like on its first run with a button and dynamically created html links in a list.

Example showing button and dynamic links

HTML: which has the button and the ListView. We will hand create the LayoutTemplate and the ItemTemplate. Our goal is to have a list of links and dynamically create them. The ItemTemplate is expecting to be bound to Url field and UrlText which Linq will nicely create for us in the code behind.

<asp:Button ID="btnClear" runat="server" Text="Clear" /> 

<br /> 
<asp:ListView ID="lvPanelGroup1" runat="server">     
                <asp:PlaceHolder runat="server" ID="itemPlaceholder" />             
            <asp:HyperLink ID="HyperLink1"                            
                           NavigateUrl='<%# Eval("Url") %>'                            
                <%# Eval("UrlText") %>

C#:The following is the code in the PageLoad. Its job is to either bind the data in the ListView using Linq or clear the ListView of all items and disable the control. Notice the Linq code where we create our object to have a Url field and UrlTextField which the ListView will use.

protected void Page_Load(object sender, EventArgs e) 
    if (IsPostBack == false) 
        List<string> Titles = new List<string>()        
            { "Title 1", "Title 2", "Title 3", "Fini"};     

        int index = 0;     

        var links = from item in Titles                 
                    select new                 
                                Url = "~Default.aspx?articleid=" + (++index).ToString(),                     
                                UrlText = item                 
        lvPanelGroup1.DataSource = links;     
        btnClear.Enabled = true; 
    else // Clear the ListView 
        lvPanelGroup1.DataSource = null;     

        // The rebinding will clear the ListView.     
        btnClear.Enabled = false; 

Here is what happens after a button press:

What happens after Clear is pressed.

Hope this helps those learning about the ListView and Linq.
