Add a SplitButton control to WPF
All free SplitButton controls I checked so far seem to lack in one way or another. Please add a SplitButton control that looks and acts like a standard control. It should both allow to act like a button (clicking on main body and dropdown arrow open a dropdown) and like an actual split button, where clicking on the main body executes a command and clicking on the arrow opens a dropdown button.
Thank you for your feedback on this idea. We have reviewed this and we will not be able to complete this suggestion in the foreseeable future. There are a number of great options from the community (e,g http://www.codeproject.com/Articles/20612/A-WPF-SplitButton) and our partners like Telerik (http://docs.telerik.com/devtools/wpf/controls/radbuttons/features/split-button)
