This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
If you haven't already done so, go into SQL Server Management Studio and open the file in the above folder and run its script. This should generate a WorldEvents database. Create an ADO entity model based upon this database.
The method of creating an entity model is not given here, since it varies according to which version of Windows Forms, Visual Studio, LINQ to SQL Classes and Entity Frameworks you are using. If in doubt, ask your trainer!
Here is one version of the entity framework to show you which tables and fields you can reference:
The database contains four tables with relationships between them.
A quick reminder before continuing - the syntax of LINQ is as follows:
// create data context
var DataContextVariableName =
// simple LINQ statemnt
var IEnumerableVariableName = (
from AnotherVariableName in
// set this to be data source of data grid view
Create a new form called frmEventsList containing a datagridview, and use LINQ to set it so that when the form loads you see a list of events (with the most recent first):
What the form might show.
Test this works, then close all your Visual Studio windows.
