asp.net mvc - Foreign keys not working in link table in Linq2Sql -


I have 3 tables subcontract, company, and a link table company.Tasbacterized I link sub-contract_ID and company_id in the table is. Foreign keys were installed in SQL and when I used to drug them in their DBML, one-to-many relations were shown to the arrows and everything looked fine, however, when coding, it seems that the relationships are not there.

When I write a selection statement, then I have to use it to get involved in the work. When I mention CompanyToSubcontract in the code, I do not have the right members available. I have company tosbacteract.com pany_id and CompanyToSubcontract.subcontract_id, but company is not with BCTActic company or company.

I have another table group with one-to-many relationships with subcontractes. I set up foreign key in the same way and it is doing great work, I can use subcontract.group_id as well as subcontract group.

Everything for the link table is being installed properly, but I can not find it to work, what is the type of trick for many foreign keys? What am I missing?

EDIT: Is not my primary key for membership of the company. Can this be the problem? It is trying now.

That was what he was. I need a primary key on the link table.

This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
