    <p>You should check which itemtype is being fired on the <code>ItemDataBound</code> event, this may or may not be the problem, as you don't have a header and footer template, however it is still good practice.</p> <pre><code>Protected Sub rp_Groups_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rp_Groups.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim chklist As CheckBoxList = DirectCast(e.Item.FindControl("chk_Items"), CheckBoxList) If chklist IsNot Nothing Then chklist.DataSource = DirectCast(e.Item.DataItem, DataRowView).CreateChildView("FK_esnServiceType_Service_Type_Categorization") chklist.DataBind() End If End If End Sub </code></pre> <p><strong>EDIT</strong></p> <p>I've just noticed that you are adding the relation after you have already binded the repeater's datasource. Try moving the <code>.databind</code> after the relation has been added.</p> <p><strong>EDIT 2</strong></p> <p>OK can you try this. Add the <code>datatables</code> to the <code>dataset</code> and set the repeaters datasource to: <code>ds.Tables(0)</code></p> <pre><code>Public Sub Fill() Dim ds As New DataSet() Dim dtServiceCategory As DataTable = ServiceTypeModel.GetService_Categories() Dim dtServiceType As DataTable = ServiceTypeModel.Search("", True) ds.Tables.Add(dtServiceCategory) ds.Tables.Add(dtServiceType) Dim relation As New DataRelation("FK_esnServiceType_Service_Type_Categorization", ds.Tables("dtServiceCategory").Columns("service_type_category_id"), ds.Tables("dtServiceType").Columns("CategorizationID"), False) relation.Nested = True ds.Relations.Add(relation) rp_Groups.DataSource = ds.Tables(0) rp_Groups.DataBind() End Sub </code></pre>

    1. COI tried both your ideas, and getting error : 'DataRowView' is a type in 'Data' and cannot be used as an expression. And when I remove datasource of checkboxlist, I am not getting any error !!!

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).
