I have an MVC action on my abstract BaseControlller like this (and this action is common across all inheriting controllers):
//
// GET: /controller/RenderForm/{formType}
[Authorize(Roles = "Administrators")]
public ActionResult RenderForm(FormType formType, BaseContentObject contentObject)

I want to define a route that have 2 optional parameters in the middle of the URL the start an end parameters are digits
[Code].....
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?

View 1 RepliesI want to add optional parameters in my routing table.For example I would like the users to browse a product catalog like this:http://www.domain.com/browse/by-category/electronics/1,2,3 etc

"~/Pages/Products/Browse.aspx"
I've already implemented URL routing in my app but there are cases where I may or may not get a paramter. In particular, I'm trying to come up with a good way to handle multi-language support. For example, if my regular URL is /SomeCategory/Friendly-Topic-URL, I want to have an optional language selector at the end but I'd like to be optional. So, if I get /SomeCategory/Friendly-Topic-URL/es, that should bring up the topic in Spanish but if get nothing, that should bring up English.
View 6 RepliesI'm trying to implement a search function on an incident logging page that is working fine. Currently I am only able to search against one criteria at a time, using the following route:
View 2 RepliesI'm using the iis7 URL Rewrite module and it's working fine, except for two things. Being new to this, I might be missing something obvious.
1) My URL gets converted from www.mysite.com/search.aspx?fName=John&sName=Smith to www.mysite.com/John/Smith. This works fine, but if I add a trailing / , a few images on the site disappear, wheras a few don't. (They're all in the same location). However, the search results are fine.
2) Is it possible to make cerain querystrings optional? Server side, this is implemented (i.e. if nothing is entered, then assume a default value). But how would this work with the URL rewrite module? e.g. www.mysite.com/John would search for John and use a default value for the sName parameter.
I have the following JSON class I am intending to use to perform management calls on my database asynchronously:
<script type="text/javascript">
var CalendarManager = {
defaultOptions: {
staffcode: 0, // required
date: 0, // required
[Code]....
Basically, my question is: how do I specify optional parameters to a WebMethod when providing JSON data?
I know I can reduce the parameters down to just the required values, and then use HttpContext.Request.Params to read the values of optional paramaters, but I would have thought the way I have tried here should have worked.
EDIT
The XMLHttpRequest.responseText value for the error is:
Invalid JSON primitive: staffcode.
This is throwing me even more off the scent of the problem :(

I have a data grid with a lot of information on it - to easily filter the data, I would like to be able to pass parameters to it. My problem is that I do not want the parameters to be required. So if I just put 1 or 2 of them in the query string, I would like for it to return all of the data related to those two parameters.I am using a data grid & stored procedures:My Stored Procedure looks like this:
[Code]...
In my stored procedure I have declared some parameters as NULL values(Optional Parameters).
In my C#.NET code I didn't use the parameters to pass values to Stored Procedure's NULL
Parameters. So I am getting Exception.
I don't want to pass parameters from my code.Because I have declared 30 parameters in my
Stored Procedure as NULL values.
Is there any other way to execute Stored Procedure from Front End without passing values to
Optional Parameters in SQL stored procedure?
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.
so I have a web programming assignment for university where I'm building a website that uses an Access database but I have hit a brick wall with something.I'm using parameterized queries to query my database. For one of my queries, I want to be able to take a bunch of parameters that are optional, and if they aren't needed I'll pass in a value of null and I'd like the part of the where clause relevant to them to evaluate to true. This is straightforward in most databases, from my understanding you could do something like to make param1 an optional parameter.
WHERE ((@param1 = ARandomColumnName) OR (@param1 = null))
However this can't be done using Access, as all parameters in a query are represented by a ?. Every ? is assumed to refer to a different parameter, so if you want to use a parameter more than one (like the above code I wrote does) then you'd have to pass it twice. This seems hacky to meSo what do I do? I have spent *hours* googling and banging my head on the desk. I'll cry if I missed something really obvious
In 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;
}
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.
View 1 RepliesI 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...

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.
Have anybody tried to create strongly typed API for ASP.NET MVC 2 async actions?
