    <p>I want to check all the check oxes and calculate the values consisted in the data attributes:-</p> <pre><code>&lt;table&gt; &lt;thead&gt; &lt;tr&gt; &lt;th style="text-align: center;"&gt;Pay? &lt;input class="chkSelectAllTimeLogs" type="checkbox" /&gt; &lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; @for (int i = 0; i &lt; 10; i++) { &lt;tr&gt; &lt;td style="text-align: center;"&gt; @Html.CheckBoxFor(model =&gt; Model.timeLogCollection[i].IsCheckedTimeLog, new { @class = "timeLogItem", data_amount = i } ) &lt;/td&gt; &lt;/tr&gt; } &lt;/tbody&gt; &lt;/table&gt; &lt;div id="divTotalAmount" style="text-align: center; font-size: 30px; font-family: Tahoma; font-weight: bold;"&gt; 0.00 &lt;/div&gt; </code></pre> <p>What i want is when i click on the the check box with class "chkSelectAllTimeLogs" then 1. All the checkboxes with class "timeLogItem" should be checked 2. The values in the data-amount should be calculated accordingly i.e. on check and uncheck of click of single or multiple.</p> <p>Currently i have 2 separate functions working as follows:</p> <p>to mark the check all i have:</p> <pre><code>jQuery(".chkSelectAllTimeLogs").click(function () { if (jQuery(".chkSelectAllTimeLogs").is(':checked')) { jQuery(".timeLogItem").prop("checked", true); } else { jQuery(".timeLogItem").prop("checked", false); } }); </code></pre> <p>to calculate the total i have:</p> <pre><code>function ehRunningTotalForTimeLogPaymentEntry() { /* This event handler monitors the checkboxes for time log items and updates the running total in a DIV. */ var total = 0; jQuery(".timeLogItem").click(function () { var amount = jQuery(this).data("amount"); if (this.checked) { total += amount; } else { total -= amount; } jQuery('#divTotalAmount').html(total).formatCurrency(); }); } </code></pre> <p>both the functions are in document ready. Please let me know how can i accomplish this?</p> <p>Regards Abhishek</p>

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.
