    <p>I'm looking for a way on how I can add a column, that shows images, to a datagrid programatically. I've been looking on how to find the solution for a long time with no success.</p> <p>The way I'm doing it now is like this:</p> <pre><code>DataGridTemplateColumn col1 = new DataGridTemplateColumn(); col1.Header = "Betaald"; FrameworkElementFactory factory1 = new FrameworkElementFactory(typeof(System.Windows.Controls.Image)); Binding b1 = new Binding("Picture") { Mode = BindingMode.TwoWay }; factory1.SetBinding(System.Windows.Controls.Image.SourceProperty, b1); DataTemplate cellTemplate1 = new DataTemplate(); cellTemplate1.VisualTree = factory1; col1.CellTemplate = cellTemplate1; dtgVerkoopsdocumenten.Columns.Add(col1); </code></pre> <p>This should create a column where I can show images. All the data I get from a database, which I store in colums like this:</p> <pre><code>System.Windows.Controls.Image image = new System.Windows.Controls.Image(); //this is on top of my class MySqlDataReader reader = cmd.ExecuteReader(); while (reader.Read()) { string naam = getKlant(reader.GetInt32(2)); if (reader.GetBoolean(7) == false) { BitmapImage betalen = new BitmapImage(new Uri("/WpfApplication1;component/Images/false.png", UriKind.Relative)); image.Source = betalen; } else { BitmapImage betalen = new BitmapImage(new Uri("/WpfApplication1;component/Images/true.png", UriKind.Relative)); image.Source = betalen; } dtgVerkoopsdocumenten.Items.Add(new DataItem { ID = reader.GetInt32(1), klant = naam, netto = reader.GetDouble(3), btw = reader.GetDouble(4), bruto = reader.GetDouble(5), datum = reader.GetDateTime(6).ToString("dd-MM-yyyy"), soort2 = soort, Picture = image }); } reader.Close(); </code></pre> <p>DataItem is an own made class where I store in all my bindings:</p> <pre><code>//more code, but the one below is the one I'm talking about public System.Windows.Controls.Image Picture { get; set; } </code></pre> <p>What I get now is absolutely nothing. I don't get any errors though.</p> <p>So my question is: how can I store the image into the datagrid without having to mess around with the xaml file too much.</p> <p>Output:</p> <pre><code>System.Windows.Data Error: 1 : Cannot create default converter to perform 'two-way' conversions between types 'System.Windows.Controls.Image' and 'System.Windows.Media.ImageSource'.

    1. CODo you need it as a 2-Way Binding Mode? If not, change it to One-Way

    2. COI tried doing that and the only thing that changes is 'two-way' to 'one-way' in the output window.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
