Question

I use a ListBox in my ASP.NET Application that display Active Directory Users. Now I want use a ListView but I don’t know how I can fill it with Data 🙁

My Application:

The User input a String (Lastname or a part of this) in a TextBox. Than the ListBox list all AD Users with the same string from the TextBox. The User who use the asp.net application selected a line in the ListBox and about a Button (btn_ShowProperties) he see all Properties of this AD User.

The Code:

protected void btnBenutzerSuchen_Click(object sender, EventArgs e)
        {
             //lboxBenutzer is the ListBox
           lboxBenutzer.Items.Clear(); 

           DirectoryEntry Entry =  new DirectoryEntry("LDAP://" + "Domain");

           string filter = "(&(objectClass=user)(objectCategory=person)(cn=" + txtBenutzer.Text + "*))";

           DirectorySearcher Searcher = new DirectorySearcher(Entry, filter);

              foreach (SearchResult res in Searcher.FindAll())
              {
                    //GetProperty is a Method to get the Informations from AD

                  string Benutzer = GetProperty(res, "sAMAccountName"); 
                  string eMail = GetProperty(res, "mail");
                  string Vorname = GetProperty(res, "givenName");
                  string Nachname = GetProperty(res, "sn");
                  string Telefon = GetProperty(res, "telephoneNumber");

                     //How I make this in a ListView? :(
                  lboxBenutzer.Items.Add(new ListItem(eMail + " | " + Benutzer + " | " + Nachname + ", " + Vorname + " | " + Telefon));
              }

        }

My Idea:

I want use a ListView because the representation of a ListBox is not the right. My Problem is it to add a line to the ListView. What can I do :/ ?

That’s easy, a ListView is a databound control, therefore you can use the same binding techniques that you would use with any data-bound controls such a GridVew, FormView, ListBox, etc

Since you already have an Enumerable (based on your code: Searcher.FindAll()), then you only have to bind it:

ASPX

<asp:ListView runat="server" ID="myListView">
    <ItemTemplate>
        <asp:Label ID="Label1" Text='<%# Eval("Benutzer") %>' runat="server" /><br />
        <asp:Label ID="Label2" Text='<%# Eval("eMail") %>' runat="server" /><br />
        <asp:Label ID="Label3" Text='<%# Eval("Vorname") %>' runat="server" /><br />
        <asp:Label ID="Label4" Text='<%# Eval("Nachname") %>' runat="server" /><br />
        <asp:Label ID="Label5" Text='<%# Eval("Telefon") %>' runat="server" /><br />
    </ItemTemplate>
    <ItemSeparatorTemplate>
        <hr />
    </ItemSeparatorTemplate>
</asp:ListView>

Code to bind it, code behind

var q = from s in Searcher.FindAll().OfType<SearchResult>()
        select new
        {
            Benutzer = GetProperty(s, "sAMAccountName"),
            eMail = GetProperty(s, "mail"),
            Vorname = GetProperty(s, "givenName"),
            Nachname = GetProperty(s, "sn"),
            Telefon = GetProperty(s, "telephoneNumber")
        };

this.myListView.DataSource = q;
this.myListView.DataBind();

Edit 1

To add a table layout:

    <asp:ListView runat="server" ID="myListView">
        <LayoutTemplate>
            <table runat="server" border="1">
                <tr runat="server">
                    <th runat="server">Benutzer</th>
                    <th runat="server">eMail</th>
                    <th runat="server">Vorname</th>
                    <th runat="server">Nachname</th>
                    <th runat="server">Telefon</th>
                </tr>
                <tr runat="server" id="ItemPlaceholder">
                </tr>
            </table>
        </LayoutTemplate>
        <ItemTemplate>
            <tr runat="server">
                <td runat="server"><%# Eval("Benutzer")%></td>
                <td runat="server"><%# Eval("eMail")%></td>
                <td runat="server"><%# Eval("Vorname")%></td>
                <td runat="server"><%# Eval("Nachname")%></td>
                <td runat="server"><%# Eval("Telefon")%></td>
            </tr>
        </ItemTemplate>
    </asp:ListView>
