C# Tutorial 21
In this part of my WPF tutorial I’ll cover how to do a ton of things with toolbars. We’ll Create the Toolbar, Add Icons, Open / Save Files, Use Shortcuts, Copy / Cut / Paste, Change Fonts in Comboboxes and more.
For best results take notes on the cheat sheet provided below as you watch and leave any questions you have.
