    <p>I'm just playing around with Visual Studio 2012 and trying to make an very simple newssite with an local SQL Server database. The problem is that the RequiredFieldValidator is not working on the textboxes. Even if the boxes are empty the database still gets updated with an empty record and i just dont know why as the validator was working fine in VS2010. If i press the submit button the errors are showing up but the database still getting updated with an empty record. Anyone have a clue why? I'm using ScriptResourceMapping in the C# file of the form if that is making any difference. </p> <p>Here's my code:</p> <pre><code> &lt;section id="addnews_panel"&gt; &lt;h2&gt;Rubrik&lt;/h2&gt; &lt;asp:TextBox ID="txtHeadlineForm1" runat="server" Width="332px" CausesValidation="True" ValidationGroup="newsForm"&gt;&lt;/asp:TextBox&gt; &lt;br /&gt; &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ControlToValidate="txtHeadlineForm1" ErrorMessage="Write something" ValidationGroup="newsForm"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;h2&gt;Rubrik 2&lt;/h2&gt; &lt;asp:TextBox ID="txtHeadlineForm2" runat="server" Width="328px" CausesValidation="True" ValidationGroup="newsForm"&gt;&lt;/asp:TextBox&gt; &lt;br /&gt; &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ControlToValidate="txtHeadlineForm2" ErrorMessage="Write something" ValidationGroup="newsForm"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;h2&gt;Ingress&lt;/h2&gt; &lt;asp:TextBox ID="txtIngressForm" runat="server" Height="99px" TextMode="MultiLine" Width="325px" CausesValidation="True" ValidationGroup="newsForm"&gt;&lt;/asp:TextBox&gt; &lt;br /&gt; &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="txtIngressForm" ErrorMessage="Write something" ValidationGroup="newsForm"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;h2&gt;Nyhet&lt;/h2&gt; &lt;asp:TextBox ID="txtNewsForm" runat="server" Height="288px" TextMode="MultiLine" Width="507px" CausesValidation="True" ValidationGroup="newsForm"&gt;&lt;/asp:TextBox&gt; &lt;br /&gt; &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtNewsForm" ErrorMessage="Write something" ValidationGroup="newsForm"&gt;&lt;/asp:RequiredFieldValidator&gt; &lt;br /&gt; &lt;asp:Button ID="btnAddNews" runat="server" Text="Lägg till nyhet" OnClick="btnAddNews_Click" ValidationGroup="newsForm" /&gt; &lt;h2&gt; &lt;asp:Label ID="lblResult" runat="server"&gt;&lt;/asp:Label&gt; &lt;/h2&gt; &lt;/section&gt; protected void btnAddNews_Click(object sender, EventArgs e) { using (dbnewsEntities db = new dbnewsEntities()) { var addNews = new tblNews(); addNews.headline = txtHeadlineForm1.Text; addNews.headline2 = txtHeadlineForm2.Text; addNews.ingress = txtIngressForm.Text; addNews.news = txtNewsForm.Text; addNews.date = DateTime.Now.ToString(); db.tblNews.Add(addNews); db.SaveChanges(); } lblResult.Text = "News added!"; } </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).
