    <p>I'm building my objects with data from my database and so far so good</p> <pre><code> public static List&lt;ImageData&gt; GetAllImageData(Guid UserId) { List&lt;ImageData&gt; imageDataList = new List&lt;ImageData&gt;(); try { SqlCommand cmd = DBHandler.getCommand("sp_Get_AllImagesForWebUser"); DBHandler.AddParameter(ref cmd, "@UserId", UserId); foreach (DataRow row in DBHandler.ExecuteSP(cmd).Tables[0].Rows) { LogWriter.Print("imagedatacontroller() new Guid(row[ImageId].ToString()): " + new Guid(row["ImageId"].ToString()), LogLevel.DEBUG); imageDataList.Add( new ImageData(new Guid(row["ImageId"].ToString()), new Guid(row["UserId"].ToString()), row["ImagePath"].ToString(), (int)row["PatientId"], row["BodyPart"].ToString(), row["ReasonForVisit"].ToString(), row["Diagnosis"].ToString(), Convert.ToBoolean(row["ConsentForResearch"]), Convert.ToBoolean(row["ConsentForEducation"]), Convert.ToBoolean(row["ConsentForStorage"])) ); } } catch (Exception e) { LogWriter.Print("Exception: ImageDataController-&gt;GetAllImageData() " + e, LogLevel.EXCEPTION); } return imageDataList; } </code></pre> <p>Then I have a webservice (.ASMX) that exposes the function and returns the List of ImageData</p> <pre><code> [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public List&lt;ImageData&gt; GetImageDataFromUser(string UserId) { return ImageDataController.GetAllImageData(new Guid(UserId)); } </code></pre> <p>But the problem is that the two Guid attributes of ImageData (ImageId and UserId) is a only-zero value Guid and I can't figure out why. I've validated with my LogWriter that its a valid and the correct Guid, but as soon as I try and expose it through my webservice its a only-zero guid.</p> <p>This is how my SOAP looks like</p> <pre><code>&lt;ArrayOfImageData xmlns="http://172.18.67.166:147/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt; &lt;ImageData&gt; &lt;ImageId&gt;00000000-0000-0000-0000-000000000000&lt;/ImageId&gt; &lt;UserId&gt;00000000-0000-0000-0000-000000000000&lt;/UserId&gt; &lt;ImagePath&gt;C:\inetpub\wwwroot\Omegapoint\data\UploadedImages\0416f1aa-9b57-4ba8-be54-398ffa9d7139.PNG&lt;/ImagePath&gt; &lt;PatientId&gt;0&lt;/PatientId&gt; &lt;CreationDate&gt;2013-03-17T22:08:10.1964107+01:00&lt;/CreationDate&gt; &lt;Bodypart/&gt; &lt;ReasonForVisit/&gt; &lt;Diagnosis/&gt; &lt;ConsentForResearch&gt;false&lt;/ConsentForResearch&gt; &lt;ConsentForEducation&gt;false&lt;/ConsentForEducation&gt; &lt;ConsentForStorage&gt;false&lt;/ConsentForStorage&gt; &lt;/ImageData&gt; &lt;/ArrayOfImageData&gt; </code></pre> <p>But the ImageId should be: </p> <pre><code>0416f1aa-9b57-4ba8-be54-398ffa9d7139 </code></pre> <p>And the UserId should be: </p> <pre><code>4bcd23a9-2815-42ef-b9ea-671b2aa08aa3 </code></pre>

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.

SQuiL has stopped working due to an internal error.

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