    <p>I went ahead and implemented the 1st option of the answer. </p> <p>It would of definitely been easier to stick to the traditional add and edit scenarios, and made use of the standard asp mvc pattern. But it was a good learning experience. </p> <p>Heres the code and markup, it still needs some more work but you get the idea. Any comments/suggestion would be appreciated. </p> <pre><code> function validate() { // Need to do form validation var balance = {}; balance.date = $("#bal_Date").val(); balance.amount = $("#bal_Amount").val(); $.post("balance/validate" , balance , function (data) { if (data.valid) { $("#existCheck").val("Valid"); checkBalanceExist(); } else { $("#existCheck").val("Not Valid"); $("#errorMessage").text(data.message); } } , 'json' ); }; function checkBalanceExist() { $("#existCheck").val($("#bal_Date").val()); // Do ajax call to see if balance exist var balance = {}; balance.date = $("#bal_Date").val(); balance.amount = $("#bal_Amount").val(); $.post("balance/doesBalanceExist" , balance , balanceCheckPost , 'json' ); }; balanceCheckPost = function (data) { $("#existCheck").val(data); if (data) { // Does Exist $("#existCheck").val("Exist"); // raise confirmation popup $('#dialog').dialog('open'); } else { // Does Not Exist $("#existCheck").val("NOT Exist"); // insert Item var balance = {}; balance.date = $("#bal_Date").val(); balance.amount = $("#bal_Amount").val(); $.post("balance/insert", balance, confirmChange ); } }; function overWriteBalance() { // insert Item var balance = {}; balance.date = $("#bal_Date").val(); balance.amount = $("#bal_Amount").val(); $.post("balance/edit", balance, confirmChange ); }; confirmChange = function () { $("#existCheck").val("Changed"); }; </code></pre> <p>and</p> <pre><code> public JsonResult validate(Balance bal) { if (ModelState.IsValid) { return Json(new { valid = true }); } else { var errorMessage = ""; foreach (var key in ModelState.Keys) { errorMessage += ModelState[key].Errors.FirstOrDefault().ErrorMessage; } return Json(new { valid = false, message = errorMessage }); } } public JsonResult doesBalanceExist(Balance bal) { var dataContext = new DataDataContext(); return Json(dataContext.Balances.ToList().Contains(bal, new BalanceEquality())); } public ActionResult Index() { var dataContext = new DataDataContext(); compModel myModel = new compModel(); myModel.bal = new Balance(); myModel.allBalances = dataContext.Balances.OrderBy(bal =&gt; bal.Date).ToList(); return View(myModel); } [HttpPost] public ActionResult Index(Balance bal) { var dataContext = new DataDataContext(); compModel myModel = new compModel(); myModel.bal = new Balance(); myModel.allBalances = dataContext.Balances.OrderBy(ball =&gt; ball.Date).ToList(); return View(myModel); } public void insert(Balance bal) { var dataContext = new DataDataContext(); dataContext.Balances.InsertOnSubmit(bal); dataContext.SubmitChanges(); } public void edit(Balance bal) { var dataContext = new DataDataContext(); var balToEdit = dataContext.Balances.Single(b =&gt; b.Date == bal.Date); balToEdit.Amount = bal.Amount; dataContext.SubmitChanges(); } } </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.
