    <p>On a custom form of mine I want to display a custom Guid field.</p> <p>I created the field the usual way via a feature:</p> <pre><code>&lt;Field ID="88813c02-799b-4fc8-8ed8-72fe668e257c" Type="Guid" Name="myGuid" StaticName="myGuid" DisplayName="My Guid" /&gt; </code></pre> <p>This field I want first set via code and display on a form. On the form I have the following control (for reference I also include a title field):</p> <pre><code>&lt;SharePoint:GuidField runat="server" ID="myGuidField" FieldName="myGuid" /&gt; &lt;SharePoint:TextField runat="server" ID="myTitle" FieldName="Title" /&gt; </code></pre> <p>The Guid field doesn't display on a regular New/Edit form - it's simply empty. In the code behind of the custom form I can do the following:</p> <pre><code>myTitle.Value = "Some Title Value"; string testValue = myTitle.Value; //--&gt;"Some Title Value" </code></pre> <p>but when trying to set the value of the Guid field - it somehow cannot be done:</p> <pre><code>string anotherValue = myGuidField.Value; //--&gt; null Guid myGuid = new Guid("7f824c3f-4049-4034-a231-85291fce2680"); myGuidField.Value = myGuid; string anotherValue = myGuidField.Value; //--&gt; still null //but myGuidField is seen as a "Microsoft.Sharepoint.WebControls.GuidField" </code></pre> <p>So somehow I'm just not able to set the Guid value programmatically and I'm neither able to only display the Guid.</p> <p><strong>Two questions:</strong></p> <ol> <li>How to display a GuidField (the GUID it contains) on a form?</li> <li>How to set the value of a <a href="http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.webcontrols.guidfield.aspx" rel="nofollow">GuidField</a></li> </ol>

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.
