问题 Shouldn't this work? If I had a break point on the last } it stops there but it never gets to the Contact Action, and the page after being posted it's just a blank page with no source code what am I missing ?

问题 I have a jqgrid where the database table has a few thousand rows, but the jqrid shows only 15 at a time. It should be displaying very quickly (it doesnt take long to query 15 rows).

The grid is defined like this: $("#Products").jqGrid({ url: url, mtype: "get", datatype: "json", jsonReader: { root: "Rows", page: "Page", total: "Total", records: "Records", repeatitems: false, userdata:

问题 ASP.NET MVC2 has strong support for using attributes on entities (validation, and extending Html helper class and more). If I generated my Model from the Database using VS2010 EF4 Entity Data Model (edmx and it's cs class), And I want to add attributes on some of the entities. what would be the best practice ? how should I cope with updating the model (adding more fields / tables to the database and merging them into the edmx) - will it keep my attributes or generate a new cs file erasing

Please guide regarding the same. 回答1: The documentation contains many examples. 回答2: @user488652: As MarkItUp uses jQuery to transform a DIV into a complex editor, I am having similar

问题 If I set a breakpoint in the compiled code (for instance in an action), I can then step through, and eventually am stepping through the generation of the View. I've found this useful a couple of times, but it's tedious as you have to step through a lot of code to get there. However, I can't set a breakpoint in view.

Now whenever I try to debug an application which targets the 4.0 .NET framework I get this error. I tried re-installing Visual Studio and the .net framework, but it keeps kappening. I don't know what to do. Also, i tried

问题 This is somewhat complicated to explain, so please bear with me. I have an ASP.NET MVC 2 project that is slowly killing me in which I'm trying to take form data and translate it into entities to create or update, depending on the context of the situation. The most relevant parts (pseudo-code): Entity Game Scalar properties EntityCollection<Platform> Platforms And the basic workflow is: Form data -> model bound to a DTO -> mapping the DTO to an EF4 entity with AutoMapper.
