    <p>I have some code where I wish to call a page method for each row in a datatable. Each row contains user information and the page method looks for additional data regarding that user, in a certain time period. If such data exsts, the idea is to then append the data as a new row to the current row. If no such data exists, move on to the next row.</p> <p>I begin my code with:</p> <pre><code> $.when(GetStartDate(), GetEndDate()) .then(function () { GetSchedules(); }) .fail(function () { failureAlertMsg(); }) </code></pre> <p>First I retrieve start and end dates via page methods. This works fine. Then I try to call a method for each datarorow in the table:</p> <pre><code> function GetSchedules() { $('.DataRow').each(function () { GetUserSchedule($(this)); }); } </code></pre> <p>This to works no problem. I pass the current data row to a new function which is:</p> <pre><code> var currDataRow; var currUserID; function GetUserSchedule(dr) { currDataRow = dr; currUserID = currDataRow.find('td').eq(0).text().trim(); $.ajax({ type: "POST", url: "mypagewithjqueryurl.aspx/GenerateUserSchedule", data: "{'StartDate':'" + startDate + "', 'EndDate':'" + endDate + "', 'UserID':'" + currUserID +"'}", //params contentType: "application/json", dataType: "json", success: function () { alert('Succeeded'); }, error: AjaxFailed }); } </code></pre> <p>When I step through the code, the function is called for each row, currDataRow and currUserID is populated as expected, and the ajax call is performed and here is where the problem lies. The call is made but neither success nor error functions are called until the calls are completed for all rows. Then the success method is called for each row but the required data has been lost.</p> <p>How can I restructure my code so that the success function is called for each ajax request?</p> <p>Thanks in advance for any insight.</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.
