    <p>This jquery works:</p> <p><a href="http://jsfiddle.net/7DXSL/1/" rel="nofollow">http://jsfiddle.net/7DXSL/1/</a></p> <p>BUT, in my C# page, this jquery doesn't work:</p> <pre><code>$(document).ready(function() { var $txtFirstNumber = $('#&lt;%= fvLineItemDetail.FindControl("txtFirstNumber").FindControl("txtData").ClientID %&gt;'); var $txtSecondNumber = $('#&lt;%= fvLineItemDetail.FindControl("txtSecondNumber").FindControl("txtData").ClientID %&gt;'); var $txtTotal = $('#&lt;%= fvLineItemDetail.FindControl("txtTotal").FindControl("literalStyle").ClientID %&gt;'); $txtFirstNumber.live("change", calculate); $txtSecondNumber.live("change", calculate); function calculate() { $txtTotal.text(parseInt($txtFirstNumber.val()) + parseInt($txtSecondNumber.val())); } }); </code></pre> <p>The calculate function is being called when the value in $txtFirstNumber or $txtSecondNumber changes and loses focus, but the three variables inside the function are undefined and not being recognized as global. Any ideas?</p> <p>Edit: Here is some more code as requested...</p> <pre><code>&lt;asp:FormView ID="fvLineItemDetail" runat="server" EnableViewState="true"&gt; &lt;ItemTemplate&gt; &lt;div class="col"&gt; &lt;control:TextBoxPDSL ID="txtFirstNumber" runat="server" cssClass="input" Text="5" /&gt; &lt;/div&gt; &lt;div class="col"&gt; &lt;control:TextBoxPDSL ID="txtSecondNumber" runat="server" cssClass="input" Text="3" /&gt; &lt;/div&gt; &lt;div class="col"&gt; &lt;control:TextBoxPDSL ID="txtTotal" IsReadOnlyLocked="true" runat="server" cssClass="input" /&gt; &lt;/div&gt; &lt;/ItemTemplate&gt; &lt;/asp:FormView&gt; </code></pre>

    1. COwhat html does this actually generate? it's likely a case of your c# code not returning what you expect it to.

    2. COI believe the generated HTML is correct. If I re-define the variables inside the function, it works. I don't want to have to do it twice though.

    3. CODoes this javascript live in it's own file or is it embedded in the aspx page? If it's in its own file then it's not getting run through asp.net and hence the asp.net code embedded in your jquery selectors isn't going to work. Try moving it into a script tag in your aspx page and see if that fixes it.

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.
