    <p>I have a LinqDataSource and a RadComboBox set up, so that the combobox shows the query results on demand. The table has 1000 or so rows and it takes a lot of time to load that page because for some reason RadComboBox keeps loading everything.</p> <p>So what is wrong with the code below? I have nothing regarding cbAuto in the code-behind file</p> <pre><code>&lt;asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="Webshop.Entities" EntityTypeName="" OrderBy="Name, FromDate, TillDate" Select="new (AutoID, Name, FromDate, TillDate, Comment)" TableName="Autos"&gt; &lt;/asp:LinqDataSource&gt; &lt;telerik:RadComboBox ID="cbAutos" runat="server" Width="900px" DropDownWidth="900px" EmptyMessage="Chosse an autotype" HighlightTemplatedItems="True" Filter="Contains" LoadingMessage="Loading..." DataTextField="Name" MaxHeight="300px" DataValueField="AutoID" ShowDropDownOnTextboxClick="False" DataSourceID="LinqDataSource1" EnableLoadOnDemand="True" EnableVirtualScrolling="True" ItemsPerRequest="100"&gt; &lt;HeaderTemplate&gt; &lt;table style="width: 850px;"&gt; &lt;tr&gt; &lt;td style="width: 300px;"&gt;Autotype&lt;/td&gt; &lt;td style="width: 100px;"&gt;Date (from)&lt;/td&gt; &lt;td style="width: 100px;"&gt;Date (till)&lt;/td&gt; &lt;td style="width: 150px;"&gt;Comment&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;table style="width: 850px;"&gt; &lt;tr&gt; &lt;td style="width: 300px;"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "Name")%&gt; &lt;/td&gt; &lt;td style="width: 100px;"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "FromDate")%&gt; &lt;/td&gt; &lt;td style="width: 100px;"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "TillDate")%&gt; &lt;/td&gt; &lt;td style="width: 150px;"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "Comment")%&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/ItemTemplate&gt; &lt;/telerik:RadComboBox&gt; </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.

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