State Management :: Grab A List View's Page And Reset The List View When Returning From A Different Page

Apr 12, 2010

I'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).

MVC :: How To Pass All The Option List Item From The Drop Down List To View Model

Nov 10, 2010

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...

public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

Javascript - MVC List With JQuery - Links - View To Display A List Of Products

Nov 5, 2010

I am using a strongly-typed view to display a list of products, where every li-element gets a unique id:

<ul id="product-list">
<% foreach (var item in Model.Products)
{ %>
<li <%= "id="product_" + item.Id + """ %> >
<div class="item">
<%= item.Name %>
</div>
</li>
<% } %>
</ul>

Now I want to attach to the click-event of every single li-element, so that if the user clicks on a div-element, detailed product-informationen should be loaded asynchronously into a details-pane. I know how I can use jQuery to invoke an action-method ajax-style and also how to display the json-result which contains the product-details, BUT I have no idea, how I could attach the onclick-event to every single div, so that I can use the productId to load the details.

MVC :: Update A Dropdown List In 2 RC 2 View

Mar 9, 2010

I was trying to implement a dynamic update of a dropdown list in an ASP.NET.MVC2 RC 2 view. My code didn't work. So, in order to verify my approach, I resorted to a published code, which supposedly should be correct: In the View:

<%= Html.DropDownList("Numbers",(IEnumerable<SelectListItem>)ViewData["Services"]) %>
<select id="Select1">
</select>
<input type="button" id="Button1" value="Fill By Array" />
<script language="javascript" type="text/javascript">
$(function() {
$("#Button1").click(function(e) {
e.preventDefault();
var data = [];
$.getJSON("/Home/GetListViaJson", null, function(data) {
data = $.map(data, function(item, a) {
return "<option value=" + item.Value + ">" + item.Text + "</option>";
});
$("#Select1").html(data.join(""));
});
});
});
</script>
In the Controller:
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
//ViewData["Message"] = "Welcome to ASP.NET MVC!";
ViewData["Numbers"] = GenerateNumbers();
return View("Index");
}
[AcceptVerbs(HttpVerbs.Get)]
public JsonResult GetListViaJson()
{
return Json(GenerateNumbers());
}
private static List<SelectListItem> GenerateNumbers()
{
var numbers = (from p in Enumerable.Range(0, 20)
select new SelectListItem
{
Text = p.ToString(),
Value = p.ToString()
});
return numbers.ToList();
}
public ActionResult About()
{
return View();
}
}

The Html.DropDownList was correctly populated on PageLoad() event. But the GetListViaJson() action method, when called on the button event, did not update the "Select1" element. how to solve this update problem.

MVC :: Create A Details View That Also Contains A List?

Mar 30, 2011

How would i create a details view that also contains a list?

My aim is to have a details view that displays information about a person and then have a list on the same page that displays facts about that person.

Currently, my details view is working fine. I just need to add the list part. The details view inherits Models.MyViewModel which is a custom class as the details come from multiple tables.
