Accessing Static MVC Controller Method From View
Mar 16, 2011
I've got an .aspx page with this in it:
<%@ Import Namespace="System.Web.Mvc" %>
<%= AssetController.ScriptTag("/js/Community/CommunityWizard.js")%>
And I have an AssetController class:
Imports System.Web.Mvc
Public Class AssetController
Inherits Controller
Public Shared Function ScriptTag(ByVal src As String) As String
Return String.Format(
"<script type='text/javascript' src='/js.mvc?src={0}&{1}'></script>",
System.Web.HttpContext.Current.Server.UrlEncode(src),
New BuildVersion().ToString()
)
End Function
End Class
The project has a reference added to the 3.0.0.0 version of System.Web.Mvc assembly. When I try to view the page in a browser, I get a HTTP 500 with this message:
BC30007: Reference required to
assembly 'System.Web.Mvc,
Version=3.0.0.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35'
containing the base class
'System.Web.Mvc.Controller'. Add one to your project.
What gives? I don't understand why I can use this controller everywhere in our ASP.NET Forms/MVC hybrid application, but not in a view. EDIT: In fact, when I type <% System.Web. into the .aspx view, Mvc doesn't even appear in Intellisense!

i have created a controller method that just update a record in the database.
and i call this method using the following code
<%
: Html.ActionLink("Perform
Calculation",
"Calculate")%>
but the problem is that when i click on the Perform Link an error will be raised indicating that it can not find the Calculate view.
so how i can enforce my application to call the Calculate controller method to perform the update and to keep the user in the current page .(the index page).

In MVC2 does every single controller method have to map to a DIFFERENT view?Or can I make two methods map to the same view?

I have just started using MVC. I created the MVC application and was playing around with it.When you call the http://localhost/home/Index/ on the sample MVC application the Index method of the controller home gets invoked and the view Index.aspx is displayed and similarly when we call http://localhost/home/About/ then the About method of the Home controller is invoked and the About.aspx page is displayed

I have a javascript library and in there i have a method that is called from my view. Here it is:
<li><a href="javascript:void 0" onclick="deleteAll('image', '<%= ViewData["FileGroupId"]%>')"><div><%=GetGlobalResourceObject("default", "Delete_all") %></div><div></div></a></li>
and here is my js code in the javascript library:
var deleteAll = function(module, groupId) {
jConfirm(_deleteConfirmAll, _deleteAll, function(r) {
if (r) {
showProgress();
$.ajax({
cache: false,
type: "POST",
url: _baseUrl + "/" + module + "/deleteall/" + groupId,
success: function(msg) {
if (msg == '0') {
location.href = _baseUrl + '/' + module;
}
else {
jAlert(msg, _errorTitle);
}
hideProgress();
}
});
}
});
}
My problem is that i cant reach my controller. Here is my controller code:
#region common methods
List<.CMS.Core.File> GetList(int groupId)
{
List<CMS.Core.File> list = new List<CMS.Core.File>();
CMS.Core.FileFilter filter = new CMS.Core.FileFilter();
filter.GroupId = groupId;
int res = CMS.Core.File.Search(_connection, filter, ref list);
return list;
}
#endregion
public ActionResult DeleteAll(int groupId)
{
List<CMS.Core.File> list = GetList(groupId);
foreach (File item in list)
{
item.Delete();
}
return Json(list);
}
And at last her is my Index method
public ActionResult Index(int? id)
{
if (Request.IsAjaxRequest())
{
JsonPaging paging = new JsonPaging();
int offset = 0;
int page = 0;
if (!String.IsNullOrEmpty(Request.QueryString["page"]))
{
Int32.TryParse(Request.QueryString["page"], out page);
}
if (page > 0)
{
offset = (page * paging.PageSize) - paging.PageSize;
}
FileFilter filter = new FileFilter();
filter.Deleted = false;
filter.MaxRecords = paging.PageSize;
filter.Offset = offset;
if (!String.IsNullOrEmpty(Request.QueryString["keywords"]))
{
filter.FilterType = FilterTypes.AND;
filter.Name = Request.QueryString["keywords"].ToString();
}
if (!String.IsNullOrEmpty(Request.QueryString["sort"]))
{
filter.OrderBy = Request.QueryString["sort"].ToString();
if (!String.IsNullOrEmpty(Request.QueryString["direction"]))
{
filter.OrderBy = filter.OrderBy + " " + Request.QueryString["direction"].ToString();
}
}
if (id > 0)
{
filter.GroupId = id.Value;
}
List<CMS.Core.File> items = new List<CMS.Core.File>();
int results = CMS.Core.File.Search(_connection, filter, ref items);
foreach (CMS.Core.File current in items)
{
JsonItem item = new JsonItem();
item.Id = current.Id;
item.Name = current.Name;
item.ImageText = current.ImageText;
item.Aperture = current.Aperture;
item.TakenOn = current.TakenOn;
item.Camera = current.Camera;
item.ExposureTime = current.ExposureTime;
item.FocalLenght = current.FocalLenght;
item.Tags = current.Tags;
item.Url = current.Url;
item["Active"] = current.Active.ToString();
item["Created"] = current.Created.ToString();
paging.Items.Add(item);
}
return Json(paging, JsonRequestBehavior.AllowGet);
}
else
{
ViewData["FileGroupId"] = id;
return View();
}
}

I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}

I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?

I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?

I have an image folder stored at ~/Content/Images/
I am loading these images via
<img src="/Content/Images/Image.png" />
Recently, the images aren't loading and I am getting the following errors in my error log. What's weird is that some images load fine, while others do not load.
what is wrong with my routes? Am I missing an ignore route for the /Content/ folder?
I am also getting the same error for favicon.ico and a bunch of other image files...
<Fatal> -- 3/25/2010 2:32:38 AM -- System.Web.HttpException: The controller for path '/Content/Images/box_bottom.png' could not be found or it does not implement IController.

So i have some existing functionality from an older ASP.Net app that is a static class.
Say there's a static method in that class that returns a dataset that I would like to bind to something like a gridview or whatever I can build using MVC3.

Using MVC2 and C#:
I have textbox that is going to be used for searching. I would like to access the data entered in this textbox in the Controller, so I can filter results in my list. I've found a couple ways to accomplich this, but haven't been successful with any. The way that I like the most is using action method parameters. Here's what I have setup; can someone tell me where I am going wrong or supply a simple example:
I have a SearchDetails view that is basically a textbox:
[Code]....
Here's the search details method from the controller:
[Code]....
Here's the search results method from the controller (where I'm trying to access the data from the textbox):
[Code]....
I added a break on the line with 'test' string and 'txtInvestigator' is null. I've also tried to make these methods GET requests and try to access the textbox value directly with Request.QueryString. It seems like I'm close, but must be missing something fairly obvious. As an aside, I already have a List() method in the controller that lists all the items from a table in my DB so I am making a little progress!

I'm overriding the OnActionExecuting method in a base Controller. When a form gets posted - anywhere, I want to check for a certain form element in this method. In any Controller method I can just include the FormCollection as one of the params in its signature, but if I try that with the OnActionExecuting method I get an error saying that there's no suitable method to override. How can I get past this?

Aplogies if this has been discussed before but I couldn't find an answer.
I'm trying to use jquery/Ajax to access some webmethods in my codebehind. This is fine, but I would in my function like to reference a placeholder (phStory in the code below) on my page and also load a usercontrol into that placeholder.
Unfortunately I get the message: "An object reference is required for the non-static field, method, or property 'TestControls.phStory' " and similar for the usercontrol. Does anyone know how I can still access my placeholder and usercontrol from within this.
It has to be stati as it's a WebMethod but this then throws up these errors.

In a webforms application, it's possible to add a server control to the markup and then access that control from the corresponding code behind file, but I'm not sure of the MVC equivalent of this functionality.
I've been looking at some tutorials, and it appears that in MVC applications, instead of using server controls, the examples are using HTML helpers, such as Html.TextBox, etc.
However, while I can find examples html helpers in views, I can't find any examples of how these helpers are accessed in the controllers, so I've declared an Html.TextBox in my view but don't know how to access its value in the controller when I hit enter.
