Handle Optional Parameters In URL Routing?
Jun 2, 2010
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.

I would like to have two different welcome pages for a site.How could I handle this? I've looked at routing but I'm not sure if global.asax.cs is the correct place to place this into.
www.mycompany.com should display generic information. Displaying view Home/Default.aspx
www.mycompany.com?id=1 should display welcome customer x. Displaying view Home/Welcome.aspx

What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution?

How to handle asp.net mvc routing along with asp.net webform routing. I have merged my mvc app into my existing web application. In my web application i have implement routing as below:
routes.Add("View Product Details", new Route("Product/{City}/{Manufacturer}/{Name}/{ProductID}/{*ProductType}"));
Similarly i have implemented routing in mvc as below
routes.MapRoute("Product Details",
"Product/{City}/{Manufacturer}/{Name}/{ProductID}/{ProductType}",
new
{
controller = "Home",
action = "ProductDetails",
City= UrlParameter.Optional,
Manufacturer= UrlParameter.Optional,
Name= UrlParameter.Optional,
ProductID= UrlParameter.Optional,
ProductType= UrlParameter.Optional
});
How to handle both pages, as one is custom web form while other is asp.net mvc view?

I'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 :(

However, all the following are correctly routed to the List action in my controller:

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.

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 have been using using System.Web.Routing for url routing in global.asax file code is as below.
public static void RegisterRoutes(RouteCollection routes) {
routes.MapPageRoute("Home", "", "~/Home.aspx");
routes.MapPageRoute("Posts", "Posts/{blog_url}", "~/blog-description.aspx");
}
protected void Application_Start(object sender, EventArgs e) {
RegisterRoutes( RouteTable.Routes);
}
Now this works fine on local but when i move the same to live it shows error 404 .I want to create a log actually what url is called.

I have a small problem:
Example:
RouteCollection routes
routes.MapPageRoute("Product","{ProductName}","~/Product.aspx")
Address on browser:
localhost:port/Software/VisualStudio
Error: HTTP Error 403.14 - Forbidden (because that Route is not exists).
How can i catch errors when routes are incorrect or not exist?

I consider the following an error, and not a feature:
When posting a request, any parameters are held in the HttpContext.Request.Form as key/value pairs. This is perfectly fine for the recipient of the request. Unfortunately, however, further down the chain these values still exist and take precedent in binding over new parameters created during processing.
This is obvious in the RenderAction scenario. If a new parameter is created in a view and passed through RenderAction, if the parameter has the same name as one of the initial request parameters (or a form field for that matter), then MVC Binding will bind the initial request form value to the Action being called, and not the new parameter being defined in the RenderAction call. What's even more frustrating, is there is no easy way to override the initial form values.
It really does not make sense that a value defined in one context, should live throughout the entire processing context... at least without the developer being able to determine it should remain. At a minimum, any new parameter defined in the process with the same name should either a) be received as a parameter and not a form value; or b) override the form value.
