    <p>I'm using a <strong>strongly typed <code>DataSet</code></strong> for which manually adding rows will be error prone. I'm providing <strong>factory methods</strong> to create rows properly. I'd like to guide consumers of my class away from the generated <code>Add*Row</code> methods on the <code>*Table</code> classes. </p> <p><strong>Adding <a href="http://dotnettipoftheday.org/tips/ObsoleteAttribute.aspx" rel="nofollow noreferrer">Obsolete attributes</a> to the generated methods</strong> would do the trick. Sadly, they would be removed the next time the code is generated. </p> <p>I can't use <strong><a href="http://msdn.microsoft.com/en-us/library/bb546176.aspx" rel="nofollow noreferrer">partial methods</a></strong> in the non-generated code because the VS2008 DataSet designer doesn't use them.</p> <p><code>MyType.Dataset.Designer.cs</code> looks a little like this:</p> <pre><code>public partial class ThingyDataTable : global::System.Data.DataTable, global::System.Collections.IEnumerable { // I'd love an [Obsolete("Please use the factory method.")] here. // I can't use a partial method, as this method isn't partial. [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public ShelfRow NewShelfRow() return ((ShelfRow)(this.NewRow())); } } </code></pre> <p>Is there some way I can add an <code>Obsolete</code> attribute from <code>MyType.cs</code>? Trying a C-style prototype doesn't work, as the member is already defined. Jamming in <code>partial</code> doesn't work because the generated member isn't <code>partial</code>.</p> <pre><code>// BROKEN EXAMPLE: public partial class ThingyDataTable { // I'd love an [Obsolete("Please use the factory method.")] here. // I can't use a partial method, as this method isn't partial. [Obsolete("Please use the factory method.")] public ShelfRow NewShelfRow(); // ERROR: member already defined. } </code></pre> <p>Is there some other way I can <strong>mark the generated method <code>Obsolete</code>?</strong> </p> <p>How else could I <strong>warn consumers</strong> away from the generated method? </p>

    1. COI would try this find and replace "[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]" for "[global::System.Diagnostics.DebuggerNonUserCodeAttribute()][Obsolete("Please use the factory method.")]". I can't find the templates for DataSets

    2. COEditing the template is a fascinating idea. How would I ensure that anyone with a stock VS2008 would end up using the template after checking out the source?

    3. COIf you could find the template. I think Visual Studio uses xsd.exe to generate the classes for DataSets and the template data is in the .exe or some supporting .dll.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
