    <p>I am creating a custom checkbox control to add a div after each checkbox in a checkboxlist. The class is below.</p> <pre><code>Imports System.Web.UI.WebControls Imports System.ComponentModel Imports System.Globalization Public Class MyCheckboxListCheckBox Inherits CheckBoxList Implements IRepeatInfoUser Protected Overrides Sub RenderItem(ByVal itemType As ListItemType, ByVal repeatIndex As Integer, ByVal repeatInfo As RepeatInfo, ByVal writer As HtmlTextWriter) writer.WriteBeginTag("input") writer.WriteAttribute("type", "checkbox") writer.WriteAttribute("name", UniqueID) writer.WriteAttribute("id", (ClientID &amp; "_") + repeatIndex.ToString(NumberFormatInfo.InvariantInfo)) writer.WriteAttribute("value", Items(repeatIndex).Value) Dim attrs As System.Web.UI.AttributeCollection = Items(repeatIndex).Attributes For Each key As String In attrs.Keys writer.WriteAttribute(key, attrs(key)) Next writer.Write("&gt;") writer.Write(Items(repeatIndex).Text) ' writer.Write("&lt;div id=" &amp; "mynewDiv" &amp; Items(repeatIndex).Value &amp; "&gt;&lt;/div&gt;") End Sub End Class </code></pre> <p>But I get an error when i use it in a page and call the save. The error is :</p> <blockquote> <p>startIndex cannot be larger than length of string.

    1. COI have found the solution I changed the name to be " writer.WriteAttribute("name", UniqueID & "$" & repeatIndex)" http://www.jasonlinham.co.uk/2009/04/checkboxlist-startindex-cannot-be.html Thanks to Jason Linham's blog.

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.

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