    <p>I thought of solution below because the collection is very very small. But what if it was big? </p> <pre><code>private Dictionary&lt;string, OfTable&gt; _folderData = new Dictionary&lt;string, OfTable&gt;(); public Dictionary&lt;string, OfTable&gt; FolderData { get { return new Dictionary&lt;string,OfTable&gt;(_folderData); } } </code></pre> <p>With List you can make:</p> <pre><code>public class MyClass { private List&lt;int&gt; _items = new List&lt;int&gt;(); public IList&lt;int&gt; Items { get { return _items.AsReadOnly(); } } } </code></pre> <p>That would be nice!</p> <p>Thanks in advance, Cheers &amp; BR - Matti</p> <p>NOW WHEN I THINK THE OBJECTS IN COLLECTION ARE IN HEAP. SO MY SOLUTION DOES NOT PREVENT THE CALLER TO MODIFY THEM!!! CAUSE BOTH Dictionary s CONTAIN REFERENCES TO SAME OBJECT. DOES THIS APPLY TO List EXAMPLE ABOVE?</p> <pre><code>class OfTable { private int _table; private List&lt;int&gt; _classes; private string _label; public OfTable() { _classes = new List&lt;int&gt;(); } public int Table { get { return _table; } set { _table = value; } } public List&lt;int&gt; Classes { get { return _classes; } set { _classes = value; } } public string Label { get { return _label; } set { _label = value; } } } </code></pre> <p>so how to make this immutable??</p>

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.
