I'm just wondering if there's a way to add a new checkbox item to an existing asp:checkboxlist control, when another checkbox is checked, without having to do a full postback of the page. Whether it's with javascript, jquery, ajax. Just wondering how (if at all) I can do something like this. I've been doing some research and it appears I can do a partial postback using an asp:UpdatePanel. I've never used one of these before. Does anyone have an example of how they can be used? Here's what I have, but it's still doing a full postback <pre><code><asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <tr> <td width="50%"> <asp:CheckBox runat="server" ID="chkEnglish" Font-Bold="true" TextAlign="Right" Text=" English" /> </td> <asp:Panel runat="server" ID="pnlTopLanguages"> <td rowspan="3" valign="top"> <asp:CheckBoxList ID="chkTopLanguages" CssClass="cb chkTopLangs" TextAlign="Right" runat="server" /> <asp:TextBox runat="server" ID="txtOtherLanguages" onkeyup="SetButtonStatus(this)" onclick="return clearLanguageSearchText()" Text="Other Languages..."></asp:TextBox> <asp:Button runat="server" ID="btnAddLang" Text="Add" OnClientClick="return CopyOtherLangs()" Enabled="false" /> <asp:CheckBox runat="server" ID="chkManyOtherLanguages" CssClass="cb" Font-Bold="true" Text="Many other languages" /> <cc3:AutoCompleteExtender ID="aceSearch" runat="server" MinimumPrefixLength="1" TargetControlID="txtOtherLanguages" ServicePath="~/controls/wsCommunity.asmx" ServiceMethod="GetLanguageCompletionList"></cc3:AutoCompleteExtender> </td> </asp:Panel> </tr> </ContentTemplate> </asp:UpdatePanel> </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.
