    <p>I'm new to WPF and I have some difficulties when I'm trying to populate a ListView with a list of custom objects.</p> <pre><code>internal class ApplicationCode { public int Code { get; set; } public IEnumerable&lt;string&gt; InstrumentCodes { get; set; } } </code></pre> <p>I have a list of ApplicationCode which I set to ItemsSource to a ListView. I need to display the ApplicationCode.Code as a string and for the rest of the columns a check box which can be checked/unchecked depending if the column name is contained in the InstrumentCodes collection.</p> <p>In order to set the check box I use a converter on databinding:</p> <pre><code>&lt;DataTemplate x:Key="InstrumentCodeTemplate"&gt; &lt;CheckBox IsEnabled="False" IsChecked="{Binding Mode=OneTime, Converter={StaticResource InstrumentSelectionConverter}}" /&gt; &lt;/DataTemplate&gt; </code></pre> <p>The problem I have is because I can't know which is the current column at the time of cell data binding and I can't set the ConverterParameter.</p> <pre><code>public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { ApplicationCode appCode = value as ApplicationCode; return appCode != null &amp;&amp; appCode.InstrumentCodes.Contains(parameter.ToString()); } </code></pre> <p>Small example:</p> <pre><code> Id | Code1 | Code3 | Code4 -------------------------------- 123 | True | False | True </code></pre> <p>Data for row 1: ApplicationCode.InstrumentCodes {Code1, Code4}</p> <p>There is a way to find out the column index or name? Or there is another way to solve this problem? </p>

    2. COHi Martin. The binding is made in the code behind: AcnList.ItemsSource = repository.GetApplicationCodes(); The GetApplicationCodes returns a List<ApplicationCode >

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.
