    <p>I have this structure of classes:</p> <pre><code>public class L3Message { public int Number { get; set; } public string MessageName { get; set; } public string Device { get; set; } public string Time { get; set; } public string ScramblingCode { get; set; } public List&lt;Parameter&gt; Parameters { get; set; } public L3Message() { Parameters = new List&lt;Parameter&gt;(); } } public class Parameter { public int numOfWhitespaces { get; set; } public string ParameterName { get; set; } public string ParameterValue { get; set; } public Parameter Parent { get; set; } public List&lt;Parameter&gt; SubParameters { get; set; } public Parameter() { SubParameters = new List&lt;Parameter&gt;(); } } </code></pre> <p>So, as return type from one of my Methods I have <code>List</code> of <code>L3Messages</code> (<code>List&lt;L3Message&gt;</code>), and I need to map that to <code>TreeView</code> in <code>WinForms</code> (populate <code>TreeView</code> from that <code>List</code>).</p> <p><strong>EDIT:</strong> Please notice that tree of my objects can be deeper than one level (becouse class Parameter have prop List &lt; Parmaeter > (List of Parameter object, same structure as root parameter object)), so that means recursion or something like.</p> <p><strong>EDIT2:</strong></p> <p>Here is pic of tree, but this tree is created from text file base on whitespaces, so here is all Parameters, in my tree I need only one from List of L3Message objects.</p> <p><a href="http://imageshack.us/photo/my-images/803/treeviewmessage.png/" rel="nofollow">http://imageshack.us/photo/my-images/803/treeviewmessage.png/</a></p> <p><strong>EDIT3:</strong></p> <p>I'm sure that my TreeView need to be something like this:</p> <pre><code>L3Message.Number: L3Message.MessageName +L3Message.Time +L3Message.Device +L3Message.ScramblingCode +L3Message.Parameters[0] ++Parameter.ParamaeterName: Parameter.ParameterValue ++ (same as above) L3Message.Number: L3Message.MessageName +L3Message.Time +L3Message.Device +L3Message.ScramblingCode +L3Message.Parameters[0] ++Parameter.ParamaeterName: Parameter.ParameterValue (in this occasion Value is null ) +++SubParameter.ParameterName: SubParameter.ParameterValue </code></pre> <p>Something like that</p> <p>If possible, I would like to that in separate thread.</p> <p>How can I achieve that?</p>

    1. COFirst off I think you should derive `L3Message` from `Parameter`, since it would be easier to manage. In fact it seems that `L3Message` is a special case of `Parameter`

    2. COI tried to google it, because I cannot map my logic with C# code due the fact that I'm pretty new in .NET and C#. :-)

    3. CO@JohnDoeKazama: So can you change the class structure to derive `L3Message` from `Parameter`? If you think about it, it would make things a lot easier to manage.

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.
