In SQL Server - Episode 2, we learn various methods built-in to SQL Server to transform our SQL data rows into well-formed XML.

In SQL Server - Episode 1, we explore how to read XML data from a database table into a SQL XML variable. Next, we perform a SELECT statement against the XML variable so we can output specific columns to the result pane. Finally, we learn how to fetch all the data columns from an XML variable.

"Delegates" are one of the most powerful features in C# .NET, yet one of the most misunderstood. In this video, I try to teach you what Delegates are and how they are used with Events. We also look at some built-in delegates and the events that use them.

In WPF Desktop App - Episode 4, we learn how to subscribe to the row double click event, how to make rows read-only, how to hide the new row, and how to center a window in the middle of the screen. We also make some usage of string interpolation. Music: https://www.bensound.com

In this episode, we learn how to create custom events using the "Action" delegate and subscribe to them.
