This prior post introduced commanding in Silverlight for use with MVVM. However, the built-in Silverlight commanding only works for controls that inherit from ButtonBase, such as Button and HyperlinkButton. This post provides information on implementing...
As you build your line of business (LOB) applications, you will need to process commands. In many cases, these commands are executed when the user clicks a button. For example, when the user clicks the Save button, the code needs to process a Save "command"...
