State Management :: Grab A List View's Page And Reset The List View When Returning From A Different Page
Apr 12, 2010I'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).
View 1 RepliesMVC :: How To Pass All The Option List Item From The Drop Down List To View Model
Nov 10, 2010I 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, 2010I 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 :: Drop Down List As Filter On List View?
Jan 7, 2011I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.

MVC :: Update A Dropdown List In 2 RC 2 View
Mar 9, 2010I 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.

Get Hidden Value From List View On ItemCommand?
Feb 1, 2010I have LinkButton and HiddenField in a list view. I want to get the hidden value from HiddenField, so I can store it in Session and when a LinkButton is clicked it transfer the hidden value ( stored in Session) to another page. But I get this error message "Object reference not set to an instance of an object." Here's the function:
Protected Sub lvTimeSheet_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewCommandEventArgs) Handles lvTimeSheet.ItemCommand
Dim id As HiddenField = TryCast(e.Item.FindControl("hfTimeSheetId"), HiddenField)
Dim myId As String = id.Value.ToString
Session("myId") = myId
Server.Transfer("Destination.aspx")
End Sub
The mark-up
</asp:LinkButton><asp:HiddenField ID="hfTimeSheetId1" runat="server" Value='<%# Eval("hfTimeSheetId") %>' />
Every time the LinkButton is clicked, it causes error with above error message.
C# - List View EmptyItemTemplate Not Displaying?
Jan 4, 2011I'm binding a ListView to a collection of objects which is working fine. Unfortunately when the collection is empty then I'm not getting the text in the EmptyItemTemplate element displayed as I would expect.
Markup code is
[Code]....
When the collection returns a count of zero then the EmptyItemTemplate text doesn't display. I have viewed the page source and it isn't rendered at all (rather than being hidden). I have replaced the DataSource object just with null i.e.
lvListView.DataSource = null
Just to test it and it still doesn't work. No text rendered again.
I have had this problem on other pages I have worked on (and given up and done kludge work arounds) so it's obviously just something that I am missing - doing incorrectly.

MVC :: Load Partial View With List Of Objects?
Jul 8, 2010I'm really new to MVC (just started a few weeks ago) and new to Ajax (never looked at it before today). I need some design / technical advice concerning Ajax, MVC, loading partial views, and posting / getting from a view. What I'd like to do it load a partial view that takes in a list of objects that have been queried from my db into an details-type view. The details view already has some other content that has been handeled and loaded from information pulled from my database and setup through some actions. It is strongly types to a model.
Below is the partial view I've created thus far:
[Code]....
And here's a portion of the Details page:
[Code]....
I'm not sure what to do for the Ajax.ActionLink. I'd like for a use to be able to type into the text box on it's left and hit "Add" (the Ajax link) and have the application add the content in the text box to the database. Should it be something else? An <input>? The Controller code piece is below:
[Code]....
So it should be adding the member into the repo / db and then reload the contents of the partialview. Instead, it's reloading the whole page and not just the partial view. (the url is changing from /project/details/5 to /project/membersection/).
