This was put in to simulate a DevForce behavior that was to be included in the next release (relative to the date when the tutorial was being constructed). The behavior would basically have made DataSourceUpdateMode = OnPropertyChanged the default for ComboBox bound in DevForce BindingManagers.  The decision to include this change in the product was subsequently reversed, but the tutorial code (and associated tutorial and exercise scripts) never got changed to reflect that reversal. Consequently they now reflect a behavior that you only get if you include the above code in your own solution, but which is described as behavior you "get for free" with DevForce.

Fix would involve removing said code from Beginning Solution and Ending Solutions in seven instructional units (14 total solutions), replacing it with code in the EmployeeForm that would produce the same behavior by overt means, and revising the tutorial and exercise scripts that refer to the behavior incorrectly.  I believe it is only the scripts for "Populating a Winform" that have the error, shown below:

ð      Go to the Manager ComboBox and select a different Manager. Notice the Manager’s photo updates automatically.

You don’t remember programming that? Neither do we. That’s data binding working for you.

According to the customer who reported this (Kenneth Hodges of Sipantic), the error is also made in a video.  I presume the video at issue is that for "Populating a Winform".
