    <p>Sounds like you should be wanting to use:</p> <pre><code>query = query.Where( Entity.StringProperty.Contains("SearchString") ) </code></pre> <p>This should map to:</p> <pre><code>WHERE StringProperty LIKE '%SearchString%' </code></pre> <p>This should also work for more advanced search masks such as "Mr? Sm%th", but I haven't had to test any search strings like that myself yet.</p> <hr> <p><strong>UPDATE: Based on OPs edit</strong></p> <p>It sounds like what you are asking for is something like the following:</p> <pre><code> public enum SelectedComparsionType { StartsWith, EndsWith, Contains } public static bool Like(this string searchString, string searchPattern, SelectedComparsionType searchType) { switch (searchType) { case SelectedComparsionType.StartsWith: return searchString.StartsWith(searchPattern); case SelectedComparsionType.EndsWith: return searchString.EndsWith(searchPattern); case SelectedComparsionType.Contains: default: return searchString.Contains(searchPattern); } } </code></pre> <p>This would allow you to write code as you require, i.e:</p> <pre><code>query = query.Where( Entity.StringProperty.Like("SearchString", SelectedComparsionType.StartsWith) ) </code></pre> <p>However, <strong><em>personally</em></strong>, I would replace any use of SelectedComparsionType, with a direct call to the required string function. I.e</p> <pre><code>query = query.Where( Entity.StringProperty.StartsWith("SearchString") ) </code></pre> <p>As this will still map to a SQL 'LIKE' query.</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.
