Hallo,
ich setze MVC 4 ein und suche eine Lösung, um die Daten von der DataTable in einer ListView im ASPX nur lesend anzuzeigen.
Offensichtlich liegt der Fehler in der Zuweisung von DataSourceID.
Was fehlt für DataSourceID noch in ASPX; also ohne C#?

Homecontroller.cs:
public ActionResult Projects()
{
DataTable dataTable = null;
if (ModelState.IsValid)
{
var connectionString = ConfigurationManager.ConnectionStrings["SqlConnection"].ConnectionString;
using (var connection = new SqlConnection(connectionString))
{
string query = "SELECT * FROM [Projects]";
var command = new SqlCommand(query, connection);
try
{
connection.Open();
var dataAdapter = new SqlDataAdapter(command);
var dataSet = new DataSet();
dataAdapter.Fill(dataSet);
}
catch (Exception exception)
{
//
}
}
}
return View(dataTable);
}
Projects.aspx:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<asp:Content ID="Content_3" ContentPlaceHolderID="MainContent" runat="server">
<asp:ListView ID="ListView1" runat="server" DataSourceID="Model">
<LayoutTemplate>
<table style="width: 100%; text-align: left;">
<tr>
<td style="width: 20%; text-align: center;">Beschreibung</td>
<td style="width: 20%; text-align: center;">Titel</td>
</tr>
<tr runat="server" id="itemPlaceHolder"></tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr id="itemPlaceHolder">
<td style="width: 20%; text-align: center;"><%#Eval("Beschreibung")%></td>
<td style="width: 20%; text-align: center;"><%#Eval("Titel")%></td>
</tr>
</ItemTemplate>
</asp:ListView>
</asp:Content>
