    <p>I would do an extension method :</p> <pre><code>public static class DictionaryExt { public static IEnumerable&lt;T&gt; PartialMatch&lt;T&gt;(this Dictionary&lt;string, T&gt; dictionary, string partialKey) { // This, or use a RegEx or whatever. IEnumerable&lt;string&gt; fullMatchingKeys = dictionary.Keys.Where(currentKey =&gt; currentKey.Contains(partialKey)); List&lt;T&gt; returnedValues = new List&lt;T&gt;(); foreach (string currentKey in fullMatchingKeys) { returnedValues.Add(dictionary[currentKey]); } return returnedValues; } } </code></pre> <p>The "cost" of adding values to the dictionary wouldn't change, but the cost of retrieval would be higher, but only when you know you're going with a partial match.</p> <p>Btw, I'm sure you could transform this in a single Lambda expression, but the concept remains the same.</p> <p><strong>Edit</strong>: In your example, this method would return 2 lists of values, but you can change it to merge the lists. Here is the extension method you could do :</p> <pre><code>public static IEnumerable&lt;T&gt; PartialMatch&lt;T&gt;( this Dictionary&lt;string, IEnumerable&lt;T&gt;&gt; dictionary, string partialKey) { // This, or use a RegEx or whatever. IEnumerable&lt;string&gt; fullMatchingKeys = dictionary.Keys.Where(currentKey =&gt; currentKey.Contains(partialKey)); List&lt;T&gt; returnedValues = new List&lt;T&gt;(); foreach (string currentKey in fullMatchingKeys) { returnedValues.AddRange(dictionary[currentKey]); } return returnedValues; } </code></pre> <p><strong>Edit 2</strong>: Come to think of it, you could also make it more generic. With the next extension method, it would work on any dictionary, as long as you provide a <code>comparer</code> that check what you mean by "partial match" :</p> <pre><code>public static IEnumerable&lt;TValue&gt; PartialMatch&lt;TKey, TValue&gt;( this Dictionary&lt;TKey, IEnumerable&lt;TValue&gt;&gt; dictionary, TKey partialKey, Func&lt;TKey, TKey, bool&gt; comparer) { // This, or use a RegEx or whatever. IEnumerable&lt;TKey&gt; fullMatchingKeys = dictionary.Keys.Where(currentKey =&gt; comparer(partialKey, currentKey)); List&lt;TValue&gt; returnedValues = new List&lt;TValue&gt;(); foreach (TKey currentKey in fullMatchingKeys) { returnedValues.AddRange(dictionary[currentKey]); } return returnedValues; } </code></pre>

    2. COWith the second edit, provided you pass an appropriate comparer method, you could have a dictionary key type of int, and say that 43 partially matches 343756.

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.
