    <p>how can i, in my function start to fill the parameters for the class it is supposed to return, but if an exception occurs i'll return my error class instead?</p> <pre><code>public **** function() { try { Articles articles = new Articles(); articles.articleid = 234; articles.articlename = "Milk"; articles.deleted = 0; //continue fill Articles //and an exception occurs return articles; } catch (Exception e) { Errors Error = new Errors(); Error.exceptionmessage = e.Message; Error.exceptionname = e.ToString(); Error.httpcode = 500; return Error; } } </code></pre> <p>is this possible and a good thing to do? or should i just extend all return classes with my error class, even though i will return much info with allot of null values. i would like to send as little data as possible and if my function fails i'll just send back the error.</p> <p>UPDATE</p> <p>sorry for not giving enough inforamtion about my situation this is a function that i want to use in a webservice </p> <pre><code>[OperationContract] [WebGet( ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)] **** Function(); </code></pre> <p>so i dont think i can just throw an exception. i would like to return a class of articles if all is well so i dont have to convert my data to JSON but if something goes wrong i would like to send http code 500 Internal Server Error to the client. i have not yet read all answers but i think i'll have to include my error class in all my other return classes so the client can now when something went wrong?</p>

    2. COInstead of returning an error, why don't you throw an exception? If the situation doesn't warrant an exception, then create a new class to encapsulate the return type or an error.

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.
