MVC :: Access RouteCollection In Custom RedirectToRouteResult?
Sep 26, 2010
I'm making a custom RedirectToRouteResult so I can have it return a JavaScriptResult if it's an ajaxrequest. To be able to generate the url I think I need access to the RouteCollection but how do I access it in there? Obviously the original RedirectToRouteResult is able to generate the url but I don't know how it does it.
public class RedirectToRouteResult : System.Web.Mvc.RedirectToRouteResult
{
public RedirectToRouteResult(string route, object routevalues) : base(route, new RouteValueDictionary
In my unit tests I would like to get hold of the 'views' modelstate somehow like this:
var modelState = result.ViewData.ModelState; Assert.IsFalse( modelState.IsValid );
where 'result' (ViewResult) is the result of the action 'Create' depending on the submitted DTO. My dilemma is that my action 'returns' a RedirectToRouteResult which I thought is quite nice but it might not be testable or is it?
How could I get hold of the ModelState in my scenario?
in an action, how do I get a reference to the RouteCollection object? I am using the QueryString to mantain some state variables and notice when I RedirectToAction the querystring in the redirected to action is null. So I would like to use RouteCollection.GetUrl and HttpContext.Response.Redirect to create a customized version of RedirectToAction.
I have been developing a pure MVC CMS for fun and have run into an annoying bug/feature of ASP.NET routing.Each dynamic managed page in my CMS is associated with a particular route that is pulled from the database. These are loaded at app start. When a user adds a new page or edits the Url of an existing page I need to be able to edit the RouteTable to insert/edit route accordingly.The problem is that the new route does not need to be simply added to the end of the RouteCollection, instead it may need to be inserted into a particular position. Seems logical enough except that the RouteCollection contains only a standard Insert(int idx, RouteBase route) method inherited from Collection<T> which doesn't contain the route name. The name of the route is important as I use it throughout to generate action links.Looking at reflector I can't see an easy way to extend this collection as the _namedMap dictionary is marked as private. I tried chopping the collection at the point of insert and re-adding each item again, however because there is no method to reverse lookup a route's name from the RouteCollection I cannot re-add them with the name they may have had before. So frustrating!!!Why is the name of the route not a property of the route object?Why if MS is serious about us extending MVC and Routing do they make crucial classes hard to extend?Any suggestions as to the best solution here?Edit :Ok maybe I should have been much much clearer here. I am not looking for a critique of my CMS design. I appreciate the comments but this is not what I am asking.
I have a footer that I am adding to a masterpage. Within this footer, if constructs menus based on the Current Node of the sitemap, however the sitemap is coming back as null. how to fix this issue.
Is it possible to access a parent class from within an attribute.
For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here.
He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute.
I would like to do something like the below,
public ExampleDropDownViewModel { public IEnumerable<SelectListItem> Categories {get;set;} [DropDownList("Categories")] public int CategoryID { get;set; } }
The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this?
i have a customized gridview.my grid is able to sort for each column just by 1 click in the header without any setting and overloading methods such as sorting,etc by user(programmer).(i do this successfully and work fine)users(programmers) maybe add each column in grid.such as template field,hyperlinkfield,boundfield... .for sorting, i must access datafield of columns.i can access boundfield column by this code.i can access datafield and header text and ... sample:
i want access "Name" (Bind ("Name") or Eval ("Name")) .how can i?there is a point: i dont now what is the ID (in this case "Label1") of control in templatefield.
Is there an easier/better way to access the RequestContext from within a custom Membership Provider than the following (and further, will this method even work):
I need to access some data from a custom assembly. This custom assembly is used by an RDLC report in visual studio 2010. The report has its own data source but this is for a special condition. When I use ths code below the the text box on the report throws an error showing #ERROR. Its the database call that is causing the error as I have tested without the call. I have changed the connect string in the sample below to ans it shows the syntax.
I want to build a custom validator control that inherits from BaseValidator. It will only be used on textboxes in my asp.net application. How can I get access to the textbox itself (read properties of the textbox) within the custom validator?
Here is what I have in my EvaluateIsValid function:
Dim t As TextBox = CType(Page.FindControl(Me.ControlToValidate), TextBox) Return t.Text.Length <= t.MaxLength
It can't seem to find the control, so it breaks with a null reference exception. Can I do this another way?
I've wrote a custom membership provider and a custom membership user. So far so good, I can create users / login etc, but when I try to access the custom membership user in code like this;
Code: Public Function GetOpportunities() As IQueryable(Of Opportunity) 'Dim p As CiseroMembershipProvider = System.Web.Security.Membership.Provider 'Dim _User = p.GetUser(System.Web.HttpContext.Current.User.Identity, True), CiseroMembershipUser Dim _User As Curve.CiseroMembershipUser = Nothing _User = System.Web.Security.Membership.GetUser() 'Dim _CurveUser As New CiseroMembershipUser 'Return From o In Me.ObjectContext.Opportunities Where o.ClientID = User.ClientID Return From o In Me.ObjectContext.Opportunities Where o.ClientID = _ _User.ClientID Order By o.ModifiedDate Descending End Function I get this error:
Unable to cast object of type 'CustomMembershipUser' to type 'Curve.CustomMembershipUser'. When I put a quickwatch on the object System.Web.Security.Membership.GetUser() it is of type CustomMembershipUser. The quickwatch window generates the text DirectCast(System.Web.Security.Membership.GetUser(), CustomMembershipUser) when I click onto the properties, but reevaluating the expression raises the error.
We have created a Master page that inherits off the asp.net Master class.We have also got ui controls that inherit off the standard asp.net ui control class.Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use.However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?
Im using Visual Web Developer 2010 Express and have put together a custom form using ASP controls and labels.
I now need to update an access database with the data that is captured on the form. I have added an AccessDataSource but do not know how to link the fileds to the fileds within the database so that when I click submit it updates the table.
I am using ASP.net to retrieve data from a Lotus notes DB using OLEDB connection. I use a ADOrecordset to read the values. When I open the ADo connection, I would like to store each record being read in a custom object and thereby create a collection of custom objects as ADO connection times out when kept open for long.
I then need to iterate throught the collection of custom objects to retrieve the values.
Ive integrated a custom asp.net web application into a Sharepoint site by creating a virual directory, that contains my web app files, that points to a directory in the Sharepoint inetpub folder.
On my local dev server I can access all my web app pages just fine by typing in /virtualdirectoryname/page.aspx
My Problem is that: When I deploy to my Live Test server that is internet facing, none of the pages that make a MS-Access database call will work.
The Error I receive is '[SecurityException: Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]'
I have researched the issue online and tried numerous solutions which include giving all the assemblies in my application a strong name, and modifying the security policy to trust this strong name.
My Custom Web App consists of 2 projects
1. A Class Library Project (Data Layer)
2. A Web Application Project (Web Layer)
My .mdb database file is stored at root level within the Virtual Directory.
I have 1 class in the Data Layer (ClassConnect.cs) that when instantiated, creates the ODBC connection for all other pages to use (OdbcConnection dbConn = new OdbcConnection();)
I have a Connection String stored in the web.config file that is as such. When I deploy to the Live Test Server I change the path in this connection string, because I haven't figured out yet how to get a relative path that works.
I also place the dll's for my 2 projects in the Sharepoint bin folder.
Could anyone suggest what might be the dfference between my Local Dev Server and the Live Test Server and why I might be getting these errors.
I built a base controller class inherits from Controller class to add some custom behavior to all controllers which will inherit from this base class.
My issue is when I try to access HTTPContext and Session objects in my custom base class, they are always null.
Am I doing something wrong or need missing something?
My custom base class definition:
public class ApplicationControllerBase : Controller
controllers classes definition:
public class HomeController : ApplicationControllerBase
using ASP.NET MVC 1, .NET 3.5.
UPDATE:
It seems the issue is I try to access HTTPContext in the constructor while HTTPContext is not ready yet, I tried it in the OnActionExecuted event handler and it works fine.
My question is what is the best place to access Session object in my custom controller class, that will guarantee executing my code with all controllers.
I was wondering if anyone can point me in the right direction? I have a POCO model and I am using Code First CTP. In my application, I set the database to be recreated whenever the model changes.
I would like to write custom functionality to access the model (POCO) metadata same way as EF sees it and use that to generate some source files (using T4). I would like to access the processed model not having to worry about finding properties that hold primary keys or any other conventions (implicit or not). What is the way to go about it?
I use SqlWebEventProvider to log the exceptions to sql server, and it works fine.
I also want to log custom exceptions to aspnet_WebEvent_Events table programmatically. Similar to - [URL]
WebBaseEvent.Raise(new WebErrorEvent("My Error message", null, 5000, e)); I get an error saying "Cannot access constructor 'WebErrorEvent' here due its protection level.
First and foremost ... I already made a few changes in the template, the most important one changing the methods generated for stored procedures with OUTPUT parameters and no resultset so that instead of instantiating a few OutputParameter objects, passing them to the method and extracting the values (all without any type checking) you just call the method with a few "out someType?" parameters so I do not need the very basics. I am totally confused by all those GlobalItem, EdmProperty,BuiltInTypeKind, TypeUsage and all this made of objects, all alike and all different though so as soon as I need more data than what's already used by the template I run into problems :-(What I would like is to change the WritePrimitiveTypeProperty() so that it outputs [StringLength(xxx)] for all char, varchar, nchar and nvarchar properties. But I can't find a way to get from an EdmProperty in the model to the database type in the store.anyone is interested here's the modified stored procedure mapping code for the template. The first code replaces the original in the .tt:
[Code]....
the second needs to be added into a copy of EF.Utility.CS.ttinclude that you add to your project and reference from the .tt
I've created some custom headers for my emails. I've used a breakpoint to see that they are being added to the collection correctly. I don't understand how to access these from the email that's generated though. I'm currently dropping the emails into a pickup directory on my local machine and viewing them with Windows Mail. I have "view all" headers checked in Windows mail but still don't see them when I open my emails in the pick up directory.
how to access the headers that I added? Below is an example of how I did it. I'm hoping to add things like name, address, phone... etc, and then have them visible in the email.
I have a view that is strongly typed and its model is of type LogOnModel. That LogOnModel has anotated properties like this one:
[Required(ErrorMessage = "Please enter your password")] [DataType(DataType.Password)] [Display(Name = "Password", Description = "Your secreet password")] public string Password { get; set; }
All of them has Display anotation with Display.Descripion property set. I want to create HtmlHelper extension method that will output <span> containg the value of Display.Description property. So for example if I called my extension method DescriptionFor than this code:
<%: Html.DescriptionFor(m => m.Password) %>
should produce following html: <span>Your secreet password</span>
