View on a button I have many different actions. So how to align them with the corresponding action in the controller. Means I want to know how many actions a View.For example, in the registration page.I have a button-Register and Login button. In the controller I have a registration action, an action Login. So how can I distinguish between those actions.

I am getting an exception that child actions are not allowed to perform redirect actions. Although I can understand that this might is true in most situations I do believe that the framework might allow this to pass when a Child Action is calling another child action like in this example:
I have this code in my CountryController (I compacted it a bit but the main concept remains that I have a controller with Child Actions only):
[Code]....
This exception is being thrown:
Server Error in '/' Application.
Child actions are not allowed to perform redirect actions. Description:An unhandled exception occurred during the execution of the current web request. Review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: Child actions are not allowed to perform redirect actions.
I have two different database connection strings for a web form that I have to use when running on either my local pc or web hosting.best way to determine whether I'm running locally or on the server at runtime? I have dodgy logic at the moment which uses a local file to determine whether or not, but that means having to include and change the code on every page if I ever needed to.

View 1 RepliesWe have a page that is opened in the child window using window.open. Now the user will copy the child's window Url and copy-paste it in the browser. We need to restrict this scenario. How should we do this. I mean I need to know in my page load method whether the request has come from window.open or whether the user copy-pasted the Url on the Browser's Address bar.

View 2 RepliesIn my actions, I want to pre-load the User object and set some other properties, all BEFORE the action loads. I know there are events where I can do this, but how will these objects that I set be made available in my controller's actions once the filter fires and execution is now at the action level?
example:
public actionresult SomeAction()
{
string username = this.CurrentUser.username;
}
We have a asp.net application and want to implement logging. The first idea was to use the Application_Error method in the global.asax file.
The problem is that ASP.NET very often seem to throw exceptions internally that are not caused by the application and which seem not to interfer with the users normal workflow. For example we often get HTTPExceptions, UnauthorizedAccessExceptions and others caught in this method, although there is no real error in the application.
I have an MVC action on my abstract BaseControlller like this (and this action is common across all inheriting controllers):

[Authorize(Roles = "Administrators")]
public ActionResult RenderForm(FormType formType, BaseContentObject contentObject)
[code]...
I am set up a series of pages like so...Page 1: User is presented a series of checkboxes. Each checkbox represents a group.<User makes selection and submits form, Controller validates input and send selected list to next action>Page 2: User is presented a series of checkboxes of items within the groups he/she selected in step 1.<User makes selection and submits form, Controller validates input and send selected list to next action>
View 2 RepliesLike most web applications you have a method that gets called when you log in. There are a few things that may need to get done when logged in and over time this may increase. eg. logging, welcome emails, maintenance. Should events be used to do this or is there a better way?? I'm using C# and ASP.net MVC. Update This is already in its on Service Layer class. eg.
public void Login(User user)
{
SetAuthCookie(user);
LogLogin(user, true);
SendEmails();
}
Is there a way to easily passed around an ID between controller actions on the same controller?I.E. I have an Index action which takes an ID parameter, and when a user creates a new post I would like them to go back to the index page with the same ID.Currently I am just passing it around in my view model, but it seems real cumbersome and I was wondering if there was a better way to do this?
View 1 RepliesI have a controller with the following actions...
public ActionResult YellowList()
public ActionResult RedList()
public ActionResult BlueList()
All these actions populate the same viewModel (ListViewModel).
How do I get them all to point to the same view (aspx)?
I'm trying to create a log that would keep a history of changes for a given item. For example on [HttpPost] Edit page I would log a change for a given article. So i've created a filterAttribute that would execute once the Edit action has completed successfully:
public class LogAttribute : ActionFilterAttribute
{
private int type; [code]...
I tried this:
filterContext.ActionDescriptor.GetParameters()
but this only returns "strings" as a parameter. "objectId" however is stored in a hidden field on the edit page.
I am using the Default Route as follows:
routes.MapRouteLower("Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" });
However, beacause of SEO I would also like to filter not by id but by name. Something like: Product/Show/RedBall instead of Product/Show/2345 And if RedBall is not unique what would be a good approach to do this? Maybe start using the following: Product/Show/2345/RedBall Using Id and Name as parameters in the actions?
Have anybody tried to create strongly typed API for ASP.NET MVC 2 async actions?
View 1 RepliesI am having one controller Test having following actions
(1)public ActionResult ABC (string parameter1, string parameter2)
(2)public ActionResult XYZ (string parameter1, string parameter2,string parameter3, string parameter4)
i have added following html.routelinks
<%= Html.RouteLink("ABC","ABC", new { parameter1 = 100, parameter2 = 200 } )%><br />
<%= Html.RouteLink("XYZ", "XYZ", new { parameter1 = 1000 , parameter2 = 2000 }) %>
last two parameters in XYZ action are optionals so i have not passed them in Html.routelink
routes.MapRoute("ABC", "Test/{parameter1}/{parameter2}", new { controller = "Test", action = "ABC", parameter1= 0,parameter2=0 });
routes.MapRoute("XYZ", "Test/{parameter1}/{parameter2}/{parameter3}/{parameter4}", new { controller = "Test", action = "XYZ", parameter1=0,parameter2=0 ,parameter3=UrlParameter.Optional,parameter4=UrlParameter.Optional});
In above senario in both cases same route "ABC" is called eventhough i have clicked on second Html.routelink. can anyone solve this issue ? how can i route according to route name instead of number of parameters?
I had my ASP.NET MVC actions written like this:
//
// GET: /TaxStatements/CalculateTax/{prettyId}
public ActionResult CalculateTax(int prettyId)
{
if (prettyId == 0)
return Json(true, JsonRequestBehavior.AllowGet);
TaxStatement selected = _repository.Load(prettyId);
return Json(selected.calculateTax, JsonRequestBehavior.AllowGet); // calculateTax is of type bool
}
I had problems with this because when using it in jquery functions I had all sorts of error, mostly toLowerCase() function failing.
So I had to change the actions in a way that they return bool as string (calling ToString() on bool values), so that thay return "true" or "false" (in the qoutes) but I kinda don't like.
How others handle such a case?
My setup project installs web site and executes some custom actions using a class library. That class library is copied to bin folder of the web site, and after that IIS tries to load it even though it isn't needed by the web site any how. How to prevent the class library from loading? Maybe it is possible to copy it to another directory instead of bin? Or maybe the web.config can be configured in such a way to prevent that class library from loading?
View 1 RepliesI've reated a project containing 15 pages , (inculding one for logging in )well , i've noticed that actions located in the page_load function are not executed! (i've tested with changing the text of a label and a text box) and it's in all pages except the authentification page!i've read tht it's probably due to the DATETIME class used in pages. but is there any other explanation? or is there any way to fix the problem
View 3 RepliesMy controller has three actions: Inroduction, Index and category. In my master page I have a text box and a search button. The general idea is that the user reaches the Introduction view, then types text into the textbox and clicks the search button. He then sees the Index view, while the query string holds a value by which the data the user sees is filtered. the user can choose a category and then he is redirected to the category view. How can I maintain the query string field and value (let's say "?cities=1,2,3") when I move between the actions Introduction, Index and category ? I'll just point out that the query string value will change if the user enters new text in the textbox.

I wish to be able to place a System.Web.ActionFilterAttribute on an Action Method and override the OnActionExecuting method to insert business logic which determines if the Action should be fulfilled. Can the ActionExecutingContext be used to cancel the executing Action Method and do one of the following:
Send an HTTP Status Code (and the corresponding <customError> page).Execute a different Action Method within the same Controller.
