Migrating an MVC site to Orchard Project 2 (Part 2)

I've started migrating my application into the module. The major consideration has been handling the use of LINQ to SQL and the Entity Framework together. My MVC application uses LINQ to SQL. I had to regenerate the data context with sqlmetal to resolve some odd errors when working with NHibernate. In particular my data context was generated by an old version of sqlmetal – it just needed an updated generation. I found it useful to create a BAT file to regenerate the context for me. call "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\VsDevCmd.bat" sqlmetal /server:MACHINENAME /database:DBNAME /code:DataContext.cs /language:csharp /views /functions...

Migrating an MVC site to Orchard Project (Part 1)

I have been moving an MVC web site of mine to the Orchard Project. As a developer I love working with MVC, however, I had not found a nice solution for content management. All of the solutions were too intrusive, tainting the MVC flavor of the site, or rather young projects I didn't want to invest in. A recent survey of Content Management System (CMS) solutions found me looking right at the Orchard Project. The project is not 'light', but it is very elegant. The project uses the 'MS Web Stack of love' which...

Simple method to constrain stored procedures by a collection

Passing a collection of ID's to filter a SQL query within a stored procedure is not natively supported. Consider this article which discusses methods for passing arrays into a stored procedure. Constraining a stored procedure's query has a simple work around, however. Passing the ID collection as a comma deliminated string allows the query to use LIKE to constrain the results. Note that the preceding and trailing commas are necessary. An example demonstrates how to do this easily.  DECLARE @Ids varchar(max); set @Ids = ',1,2,3,4,5,'; Select * from [TableName]     WHERE @Ids LIKE ('%,' + cast(TableID as varchar(50)) + ',%')

ASP NET MVC Version 1 Released

Version 1 of ASP.NET MVC has been released, presumably for MIX in Vegas. It's been a year following the project, and it's exciting to see MVC released after three years of development since March 16th 2007. Overview ASP.NET MVC 1.0 provides a new Model-View-Controller (MVC) framework on top of the existing ASP.NET 3.5 runtime. This means that developers can take advantage of the MVC design patterns to create their Web Applications which includes the ability to achieve and maintain a clear separation of concerns (the UI or view from the business and application logic and backend data), as well as facilitate...

Paging with Filters and Sorts added to Unifico

Two new additions were added to Unifico: filtering on fields and sorting on fields with the help of Html Extension methods. A PagingSet class was defined to contain configuration options for the paging. In this way a View can still page on more than one list and maintain complete control over the Html rendered.

Paging Helpers in Unifico, Filtered and Sorted Paging

Unifico has a few paging helpers to make service methods easily paged from a client. Essentially the framework makes consuming a page request object as simple as calling .ToList() on an IQueryable source. The object, the PageRequest, has two collections, Filters and Sorts with several constructors to make instantiation easy. The collections are rather straight forward, providing filtering and sorting ability on a paging source. The uniqueness comes from the ability to request multiple filters and sorts together, along with a paging request. This request is then execute on the IQueryable source, so if DLINQ...

The Unifico Framework’s Organization

One major aspect to Unifico is its organization through assemblies and namespacing. Assemblies are 'cut' by component to allow for component plug-ability. One major goal of the project is to allow for a component to be easily added to an existing site without conflicting with other equally significant components. With a few modifications (to come) Unifico allows for a whole component to be dropped in as a dll without recompilation by virtue of Structure Map. Currently, each component's assembly has to be added to structure map in a common class, the 'bootstrapper'. Within each component...
