Wpf-Project Update a LinQ -Join

The line in question, var orderlist = from x in cqsDC.MasterQuoteRecs, is as follows

cqsDC is the data context that represents the database in code and  MasterQuoteRecs is the variable to the table in the database and it is MasterQuoteRecs and not MasterQuote. The x represents a individual row of the table. The class MasterQuote is being used to return a  concrete data type  instead of returning an anonymous type.

Please post the data table schema of the database tables that you will be using in the query as well as what you want as the results of the query.

well, lets say I have this entity model,
  using (NorthwindEntities context = new NorthwindEntities())
So, what is it I have to do, to continue like : "context."  , after that point "MasterQuoteRecs" is within the list

Hi petra;                                                                                                  
                                                                                                           
So here is a code snippet that will work with Northwind database and display the results in a DataGridView.

// The city of the customers to be returned from the query
string cityOfCustomer = "New York";

using (NorthwindEntities context = new NorthwindEntities())
{
    // The variable results will contain a collection of customers
    // who meet the where clause
    var results = (from c in context.Customers
                   where c.City == cityOfCustomer
                   select c
                  ).ToList();

    // Display the results in a DataGridView
    dataGridView1.DataSource = results;
}

Select allOpen in new window

- writing "context"
- set a "."
- a dropdownlist opens
- but doesnt have "MasterQuoteRecs"

you have it?

Well the first thing you need to verify is that the MasterQuoteRecs database table is in the DbContext.. if it is not you need to add it to the model. Make sure that you re-compile the project when ever you update the model so that it gets reflected in code.

maybe you like to correct something, within your last post

Like what?

like:
- subject is about "Update a LinQ -Join" a JOIN
- the link, i post here, leads to stackoverflow, but at least it isnt an example to update a linq-join-string, i just see it right now.

Is what happend if smart ones have to think about : how to make the stupid ones not to missuse my question.
- how to make them stick to the real question, so they dont talk bullshit, and I have to stop them, which they take as an offence
- and so one

But its not refering to you.
So, lets get back to the real subject.
Any Idea how to update a LinQ join like:
 

var query = from cat in context.Categories
                            join prod in context.Products
                            on cat.CategoryID equals prod.CategoryID
                            orderby cat.CategoryName
                            select cat;                  
                this.dataGrid1.ItemsSource = query.ToList();

Select allOpen in new window

you are the smartest person I ever met, and I mean it
