OrderDetailsMaintenance.zip

$1.$ Include the two above files in the root of your OrderDetailsMaintenance project.

$2.$ Make sure to mark them as "Content" and "Copy Always" or "Copy if newer" in the properties window of those two files.

$3.$ Run the Scaffold$-$DbContext command to create a context class as well as a class to encapsulate the Orders objects from the associated table in the mdf file. Make sure to include the parameters for $-$Tables Customers $($only worry about the attributes associated with the text boxes, you don't need to worry about any other rows from the table$)$

$4.$ Once you have ran the command, include an app.config file and add a connection string element. Make sure to copy the connection string from your Context class to your app.config. Then edit your context to grab the connection string from the app.config $($ConfigurationManager$.$ConnectionString$["$Northwind$"].$ConnectionString$)$

$5.$ Code the Find button to Find the customer id and populate the details in the below text boxes.

$1.$ If no order is found, display a message box.

$6.$ Code the exit button

$7.$ Code the Save button to update its attributes and call Update and SaveChanges$()$ on that particular entity.

$1.$ Note: If you close the program, reopen it$,$ and search for the entity you recently updated. You may not see the changes depending on how you setup the mdf file in your project $($because it copies a new version to the bin directory each time you run the program$).$ So$,$ if you don't see your changes, don't be alarmed. PLEASE GET THE RIGHT CODING FOR THE FIND BUTTON and SAVE BUTTON RELATING TO THE DATABASE Northwind.mdf$.$ The code must match or it will not excute correctly at all. PLEASE AND THANK YOU. I found a other solution where this code shown: using $($var context $=$ new NorthwindContext$())$

$\{$

var customer $=$ context.Customers.FirstOrDefault$($c $=>$ c$.$CustomerID $==$ txtCustomerID.Text$)$;

if $($customer $==$ null$)$

$\{$

MessageBox.Show$("$Customer not found", "Find Customer", MessageBoxButtons.OK$,$ MessageBoxIcon.Information$)$;

return;

$\}$

txtCompanyName.Text $=$ customer.CompanyName;

txtContactName.Text $=$ customer.ContactName;

txtContactTitle.Text $=$ customer.ContactTitle;

txtAddress.Text $=$ customer.Address;

txtCity.Text $=$ customer.City;

txtRegion.Text $=$ customer.Region;

txtPostalCode.Text $=$ customer.PostalCode;

txtCountry.Text $=$ customer.Country;

txtPhone.Text $=$ customer.Phone;

txtFax.Text $=$ customer.Fax;

$\}$ THIS WAS IN INCORRECT CODE I Had ERROR
