Another smaller new control that is ready for the upcoming WPF Studio v3.5 maintenance release is PopupButton.

PopupButton allows you to easily define a button that can display a popup.  The popup can show any WPF content or can optionally display a ContextMenu.  The popup content and context menus can be defined in XAML or dynamically in code.

There are several display modes for the button.  It can show a split mode where the button is clickable separately from the popup portion.  The split can be removed so that the entire button displays the popup when clicked.  In this mode, you also have an option of hiding the content area and just showing an arrow indicator.  The other option is the turn off the popup portion and make it behave like a normal button.

Another great option is the ability to have the button render "flat" until the mouse moves over it, at which point the background and borders appear.

Numerous themes are included with the control.

In our next "first look" post, we will talk about a major new control for the maintenance release that uses PopupButton.
