An exception is raised saying at least one object must implement IComparable because it does not know for which column in the target entity (that which points navigation property) to order by. The 40 lines is the same no matter whether it is 40 lines that you put somewhere in your project, or if those lines come (pre-compiled, or as source) in an external library
The only thing I can say about all these people not liking it, is that maybe they never really gave it a try, because it was different from the using ADO stuff in the .NET framework? I love being able to navigate the DataContext object and query straight from my code, instead of writing external SQL queries and executing them with dataTables and dataSets. Why would I risk (given this behaviour) using the Entity Framework, for fear of having the same thing happen (I know it's not likely, but it exemplifies the point)
Develop a sample application using LINQ programming and the ADO.NET Entity Framework with IBM DB2, IDS, and U2 servers
New connection Select the IBM DB2, IDS and U2 Servers (IBM DB2, IDS and U2 Data Provider for .NET Framework) data source in the Choose Data Source dialog box.Click Continue.In the Connection Properties dialog box, enter your user name, password, server name, and database name. See Resources for more information.)To add the ADO.NET Entity Data Model item template, do the following: Select the project in Solution Explorer, point to Add, right-click, and click New Item.Select ADO.NET Entity Data Model in the Templates paneType Customer.edmx for the model name, and click Add
One annoyance I noticed was that if I was making an update in a GridView, it would error out unless I explicitly had the primary key in the GridView - and if I wanted it hidden, it was necessary to use css; it is documented here. I too disliked L2E from the get-go but decided that my opinion was not totally grounded and that I should really understand L2E before I crap on it, so, I decided to do an entire project at work with it and get down to the nuts and bolts
Dynamic query with Linq - CodeProject
For example - An employee search screen or a general purpose report which needs to execute a different SELECT statement based on a different WHERE as well as Sorting column to sort data. LINQ represent each table as one entity and where LINQ queries allows to manipulate data in type safe.But Static In this post I am going to discuss about building dynamic query with the LINQ

LINQ Objects and Web Applications By default, if your application is using in-process state management, you'll be able to store LINQ objects in Session, Application and Cache
Here I will just drop two keywords: SQL Injection and Query-Plan Reuse.) Nonetheless, in many shops the mandate is that you should use stored procedures. You would still have one set of procedures per table, but the code would be in one single include file.) SELECT * FROM sales + @yymm This is a variation of the previous case, where there is a suite of tables that actually do describe the same entity
example....I have seen this solution before, but, in the first place, how was Int...but data grid view i can.t add rows and i can.t edit in any cells? ...This broke down when I tried to use it in multiple places
As this article focus completely on join operation, if you are a beginner linq programmer, consider my previous tutorial on getting started with linq to sql. Where its needed to be written even for simple purpose, we can achieve what we need just by calling linq provided methods with proper parameters.This facilitates to make the code more meaningful and less buggy
Another possible solution is to do that in the definition of your data context which is bound to L2S Data Source control (By Context name property), but beware that will effect everywhere that uses this context. My question is: How can you combine both techniques as to produce the initial and valuable scaffolding CRUD design provided by the ASP.Net 3.5 that had help me a lot in debugging and building a proper ERD with the right primary and foreign keys
Here, in this tutorial, i will show the most basic operations such as retrieving data(select), inserting data,deleting data and modify existing data to and from xml file using linq. The example given above is for desktop app format, where it requires that the xml file is in the current directory from where the application is running
The ability to define data model classes that can be independent of the underlying database schema gives you much more agility as you build your application (since you can change the underlying column names without having to update your code). I was wondering if you had thought of providing selections of your blogs as PDF docs for download, so that we could have, for example, this LINQ series of posts all together in one place in chronological order
Just run it by VS2008 Express i had all examples by different implementation of linq, like: - Linq To Sql - Linq to XML - Linq over DataSet - XQury use cases Great! LukCAD - Tuesday, January 8, 2008 7:46:45 AM Great! So why is this a zip somewhere on MSDN that has a code file we need to compile? If this works as good as you say it does, please consider putting it in the Extensions release. Dave - Sunday, February 3, 2008 1:12:49 PM How can you handle null values with the LINQ data source control? For example I have a drop down list that controls the data displayed in a gridview
