    <p>Make your life easier and create the checkboxes with checkboxlists: <a href="http://msdn.microsoft.com/de-de/library/system.web.ui.webcontrols.checkboxlist.aspx" rel="nofollow">http://msdn.microsoft.com/de-de/library/system.web.ui.webcontrols.checkboxlist.aspx</a></p> <pre><code>&lt;asp:CheckBoxList ID="SomeElement" runat="server" AutoPostBack="true" RepeatColumns="4" EnableViewState="true"&gt; &lt;/asp:CheckBoxList&gt; </code></pre> <p>With the Repeatcolumns property you are telling the element, that you infact want 4 columns, so the control will devide your 32 elements by 4 and group those checkboxes by the pack of 8.</p> <p>After this, you can iterate through every list like this:</p> <pre><code>foreach(var cb in checkboxlistID) { if(cb.Checked) { //do something } } </code></pre> <p>On top of that, here is some old code showing you how to fill a checkboxlist with data fetched from a SQL-query. You can ignore the if expression, which is checking if there is cached data, from which to fill all the checkboxes.</p> <pre><code>using (OleDbConnection connection = new OleDbConnection(ConfigurationManager.ConnectionStrings["database"].ConnectionString)) { string Query = @"SELECT * from level"; OleDbCommand command = new OleDbCommand(Query, connection); if (Session["SavedLevelItems"] != null) { CheckBoxListLevel.Items.Clear(); List&lt;ListItem&gt; SessionList = (List&lt;ListItem&gt;)Session["SavedLevelItems"]; foreach (var item in SessionList) { try { CheckBoxListLevel.Items.Add(item); } catch { } } } else { connection.Open(); CheckBoxListLevel.DataTextField = "bez_level"; CheckBoxListLevel.DataValueField = "id_level"; OleDbDataReader ListReader = command.ExecuteReader(); CheckBoxListLevel.DataSource = ListReader; CheckBoxListLevel.DataBind(); ListReader.Close(); ListReader.Dispose(); } } </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.
