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'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
When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file.
Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.
I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:
I have a Web service which, when updated on one computer with VS2008 works perfectly fine, but on another computer does not. The critical difference is the contents of the auto-generated Reference.cs.
In the correctly functioning environment, the methods have fully qualified class names, refering to classes in a class library. However, in the problem environment, the class names are unqualified and partial classes are declared near the end of the file. E.g.
[code]....
The code is under source control. Checking out to the working environment works straight away, checking out to the problem environment will only work if the reference.cs is manually edited to be like the working environments. Transferring the project manually from problem environment to the working one only requires an "Update Web Reference" to be performed to allow compilation. Both Reference.cs files claim to be auto-generated by the same tool version. The settings from the good environment have been exported to the other. No success so far...
http://www.somepage.com/main.aspx. In this page, when I click on a link it takes me to a page http://www.somepage.com/cental.aspx?cid=200. So in the cental.aspx.cs page I did the following in the page load:
if(request.querystring["comp"].tostring() != null) { //do some thing [code].....
So I got an error like: object reference not set to an instance of reference.My problem is, I am using the same page. So when I go from some page, I will have "comp". but other times not. So when there is no "comp", how do I handle it in request.querystring?
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.
Using VS2008, I noticed that in Class Project I only have a choice of adding "service reference" where as in Web Application project, I have two choices "web reference" and "service reference".
I have used web reference. How is "service reference" different from web ref? and what's the major purpose of service ref?
I am using grid view as mentioned below, it is giving me error "object reference not set", but if comment allowpaging and pagesize lines, it works. let me know whats wrong I am doing?
I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?
I have an ASP.NET project under source control (Subversion). For various reasons, I don't want to add the Bin directory or its contents to source control, so I have it svn:ignored. DLLs are loaded into here during a Visual Studio build, and I can start with a clean directory and/or delete all the contents of this directory and still have a successful build.
I'm creating a DLL with a reference to web services (I don't have the choice to do so) but I have to add web service references to the project that uses the DLL for it to work. Example, I have the DLL called API.DLL that calls a web service called WebService.svc that I want to use in a project called WinForm. First, I have to add a "Service Reference" to WebService.svc in API.DLL. Then, I add a reference API.DLL to WinForm but it doesn't work unless I also add a service reference to WebService.svc in WinForm.
I've a an exe application developed using C. I want to add this as a reference to my asp.net application. But i'm getting an error which says like it's not an assembly or COM component.
I want my application to interact with the exe(which should be running) which will again respond with some appropriate message. Can we add a exe reference to a project? or is there any other way of doing without adding a reference?
i am trying to build a little ASP.NET 3.5 project to explore DAL concepts. While following the steps on this walkthrough:
[URL]
I am unable to figure out how to reference the TableAdapter added in the DAL section from within the App_Code directory. I tried adding the following different statements
using AccountsTableAdapter; using <projectname>.App_Code.MyTableAdpater;
where <projectname> is the solution name. When I add this to the code behind page but I keep getting an error regarding the namespace. What is the pattern I need to use to find this code in 3.5 within the App_Code directory?
is there a way of referencing a .NET 4.0 in a .NET 2.0 app? Whenever I try to compile and build I get an error saying:
Could not load file or assembly 'blahblahblah' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
Ive tried adding the Library as a project AND as a .DLL but still no luck. Unfortunately converting the .NET 2.0 to .NET 4.0 is not optional...
I am trying to return an Entity Framework 4 object with children to an jQuery JSON AJAX function but I get a circular reference error - in short my method looks like this
[WebMethod] public static JSONObject Get() { WebHelper.JSONObject lJSONObject = new WebHelper.JSONObject();
I have an dought on adding name space in project. In one one of my project I want to add "System.SserviceModel.Web" name space. But the name space is not in .net tab of refence dialog box. How can I add this reference to the .net tab window?
