    <p>I'm having an issue updating a 'bit' column in a SQL database, using C# and Entity Framework.</p> <p>I have a 'Settings' table with a NOT NULL bit column named 'Active'. When I create a record in the table and specify 'Active' in code as 'true' or 'false', the record in the database that's created is accurate and the 'Active' column contains the correct value that was specified in code. When I update the record and change 'Active' from 'false' to 'true' in code, that works as well. However, when I update the record going from 'true' to 'false', the 'Active' column in the database still contains '1' (true).</p> <p>Is this a known issue? If so, is there a workaround? I've done a fair amount of research and was unable to find anything.</p> <p>Here's my update code:</p> <pre><code>public int UpdateSetting(SettingModel settingModel) { using (var db = new EfMyDB()) { // Create a new setting record with the ID of the record to update. Setting updatedSetting = new Setting { Id = settingModel.Id }; // Attach the record. db.Settings.Attach(updatedSetting); // Update the attached record. updatedSetting.Name = settingModel.Name; updatedSetting.Value = settingModel.Value; updatedSetting.Active= settingModel.Active; // Save the database changes. return db.SaveChanges(); } } </code></pre> <p>EF 'Active' column properties:</p> <p><img src="https://i.stack.imgur.com/L1etX.png" alt="Properties in the EDMX file for the &#39;Active&#39; column."></p> <p><strong>Versions</strong>: .NET 4.0, SQL Server 2008, Entity Framework 4.1</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.
