DataSource Controls :: Add A New Item To A LINQ Query?
May 13, 2010So I'm trying to add a single item to a query I wrote. The query is then pass to the e.Result of a LinqDataSource_Selecting event. This datasource is being used by a dropdown list and label in a listview.
I am trying to add a "New" field to the end of the list.
Currently I have this working, but it seems like a really messy solution. First I make a class with the fields I need:

When Manufacturer is null, I get a NullReferenceException. The "Manufacturer.Trim()" should never be executed, because the first half of the OrElse evaluates to true. Just to test it out, I also tried this:

This actually works fine... Manufacturer.Trim() is never executed, and I get no error. Why is the Trim() statement being executed in the first case? If Manufacturer is null, then it shouldn't be.

DataSource Controls :: LINQ And C# - Accessing More Then 2 Tables In A Query
Apr 23, 2010As the title sugests, I am missing a (basic?) concept as I teach myself asp.net, linq, and C#. It has been awhile since I've done anything object oriented, so I don't know how much that is impacting this gap in my understanding. Anyhow, here is what I am trying to do. I have three SQL Server tables: PERSON, POSITION, AREA. There is a 1 to many relationship between PERSON and POSITION, and a 1 to 1 relationship between POSITION and AREA. Given the following code I verify who the person is who has logged into the browser:
[Code]....
I want to be able to return all of the AREAs the person is able to access, based on the position they currently hold. I am able to easily do this in a SQL Server query, and I am sure I can do this with a SQL stored procedure once I pass the EMPLOYEE_ID to the procedure. However, I would rather do this in the page_load event, and load the returned results into gridview1 for the viewer. The issue I am running into is in building the LINQ query. When I try to build it, I can only get access to two of the three tables, depending on which table I select with db. Is it possible to access all three tables in the same query?
