    this.ViewContext.RouteData

should do the trick.

Let&#39;s have a button `Command` property bound to a custom command.

When should I implement `ICommand` and when derive from `RoutedCommand`? I see that **RoutedCommand implements ICommand**.

In which case could I need to implement an `ICommand`? 
What about MVVM model? Which one suits better for this purpose?

ICommand vs RoutedCommand

I was researching how to get the memory offset of a member to a class in C++ and came across this on &lt;a href=&quot;http://en.wikipedia.org/wiki/Offsetof&quot;&gt;wikipedia:&lt;/a&gt;

&gt; In C++ code, you can not use offsetof to access members of structures or classes that are not Plain Old Data Structures.

I tried it out and it seems to work fine. 

    class Foo
    {
    private:
        int z;
        int func() {cout &lt;&lt; &quot;this is just filler&quot; &lt;&lt; endl; return 0;}

    public: 
        int x;
        int y;
        Foo* f;
    
        bool returnTrue() { return false; }
    };

    int main()
    {
        cout &lt;&lt; offsetof(Foo, x)  &lt;&lt; &quot; &quot; &lt;&lt; offsetof(Foo, y) &lt;&lt; &quot; &quot; &lt;&lt; offsetof(Foo, f);
        return 0;
    }

I got a few warnings, but it compiled and when run it gave reasonable output:

    Laptop:test alex$ ./test
    4 8 12

I think I&#39;m either misunderstanding what a POD data structure is or I&#39;m missing some other piece of the puzzle. I don&#39;t see what the problem is. 


Why can&#39;t you use offsetof on non-POD structures in C++?

If I want to directly access the `RouteData` (the current action or parameter values for example) from the `View`, rather than having to pass it in from the controller as part of the `ViewData`, what class would i use?

In asp.net MVC the &quot;homepage&quot; (ie the route that displays when hitting www.foo.com) is set to Home/Index .

- Where is this value stored? 
- How can I change the &quot;homepage&quot;? 
- Is there anything more elegant than using RedirectToRoute() in the Index action of the home controller?

I tried grepping for Home/Index in my project and couldn&#39;t find a reference, nor could I see anything in IIS (6). I looked at the default.aspx page in the root, but that didn&#39;t seem to do anything relevent.

Thanks

Set &quot;Homepage&quot; in Asp.Net MVC

I am using the autocomplete feature of jQuery. When I try to retrieve the list of more then 17000 records (each won&#39;t have more than 10 char length), it&#39;s exceeding the length and throws the error:


&gt; Exception information: &lt;br/&gt;
    Exception type: InvalidOperationException &lt;br/&gt;
    Exception message: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Can I set an unlimited length for `maxJsonLength` in `web.config`? If not, what is the maximum length I can set?

I am looking for a method to disable the browser cache for an **entire ASP.NET MVC Website**

I found the following method:

    Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
    Response.Cache.SetNoStore();

And also a meta tag method (it won&#39;t work for me, since some MVC actions send partial HTML/JSON through Ajax, without a head, meta tag).

    &lt;meta http-equiv=&quot;PRAGMA&quot; content=&quot;NO-CACHE&quot;&gt;

But I am looking for a simple method to disable the browser cache for an entire website.

If the controller action has the OutputCache attribute specified on an action, is there any way to clear the output cache without having to restart IIS?

    [OutputCache (Duration=3600,VaryByParam=&quot;param1;param2&quot;)]
    public string AjaxHtmlOutputMethod(string param1, string param2)
    {
      var someModel = SomeModel.Find( param1, param2 );

      //set up ViewData
      ...

      return RenderToString( &quot;ViewName&quot;, someModel );
    }

I&#39;m looking at using `HttpResponse.RemoveOutputCacheItem(string path)` to clear it, but I&#39;m having trouble figuring out what the path should be to map it to the action method. I&#39;m going to try again with the aspx page that is rendered by ViewName.

Possibly I&#39;ll just manually insert the output of `RenderToString` into the `HttpContext.Cache` instead if I can&#39;t figure this one out. 

&lt;b&gt;Update&lt;/b&gt;

Please note that the OutputCache is VaryByParam, and testing out a hardcoded path &quot;/controller/action&quot; does not actually clear the outputcache, so it looks like it has to match &quot;/controller/action/param1/param2&quot;.

That means I&#39;ll probably have to revert to object level caching and manually cache the output for `RenderToString()` :(

I have a strongly-typed Partial View that takes a ProductImage and when it is rendered I would also like to provide it with some additional ViewData which I create dynamically in the containing page. How can I pass both my strongly typed object and my custom ViewData to the partial view with the RenderPartial call?

    var index = 0;
    foreach (var image in Model.Images.OrderBy(p =&gt; p.Order))
    {
      Html.RenderPartial(&quot;ProductImageForm&quot;, image); // &lt; Pass &#39;index&#39; to partial
      index++;
    }
