Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]

View 3 RepliesI've used DataAnnotations attribute DisplayName successfully using MVC model binding, and even with WPF/Silverlight model binding and of course it works just fine, but now I'm on a project that I'm forced to use VB.NET 3.5 WinForms.
I have a Linq2Sql model and I created a partial class for one of my classes and included a MetadataType attribute to point to a metadata class. I added a DisplayName attribute to a property in the metadata class. I then bind my datagridview with an IQueryable(Of mydatatype), but the column name in the grid is the Property's name and not the DisplayName.
Am I missing something? Is there something else I need to do to get the datagridview to use the DisplayName?
In my Model class:

To correct this error I use the given help that microsoft provides below and i am still getting the error messages can anyone assist me with the source codes if i send some code snippets?Check that the type definition and its reference both use the same spelling.
Check that the type definition is accessible to the reference. For example, if the type is in another module and has been declared Private, move the type definition to the referencing module or declare it Public.If the type is defined, but the object library or type library in which it is defined is not registered in Visual Basic, click Add Reference on the Project menu, and then select the appropriate object library or type library.

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

I'm trying to implement the GetHttpContext function from HtmlHelperTest.cs in VB.NET using Rhino Mocks, but I'm getting "Type 'HttpContextBase' is not defined." The compiler suggests changing it to HttpContext, but when I do that I get a run time error that a sealed class cannot be mocked.My test project references System.Web and also imports that namespace. Is there something else I need to do in order to get the HttpContextBase type to be visible to the code I'm witting?
