    <p>Using Visual Studio 2012 and SQL Server 2012</p> <p>Here is the situation:</p> <p>A website I am building is not updating data that is loaded into fields from a SQLDataSource. The data loads just fine into their appropriate text boxes, but when I go to edit the data and activate a button click, it looks like the revisions are cleared and the page refreshes to the original loaded data. As far as I can tell, my code looks correct, but that is obviously not the case.</p> <p>Addition info:</p> <p>I have the page set up in a containerplaceholder with a master page.</p> <p>Here is my mark up:</p> <pre><code>&lt;asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server"&gt;

&lt;/div&gt; &lt;!-- Employee Type --&gt; &lt;div class="lblemployeetype"&gt; &lt;asp:Label ID="lblEmployeeType" runat="server" Text="Employee Type"&gt;&lt;/asp:Label&gt; &lt;/div&gt; &lt;div class="txtemployeetype"&gt;

Guidance
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).
