title: WPF SplitButton?
body: <p>I've just spent a very frustrating afternoon trawling Google looking for a commercial-grade WPF <code>SplitButton</code> control that will work in a <code>ToolBar</code>. A <code>SplitButton</code> is one where you can click on the main part of the <code>Button</code> to take a default action, or click on a little triangle on the right to get a drop-down menu of alternate actions).</p>
  
  <p>I found several on the web (including the one on CodeProject, and including the two on CodePlex). None of them work properly in a <code>ToolBar</code>--they either don't appear at all, or they don't have toolbar button styling. I even looked at some commercial offerings, like ActiPro's pop-up button (in their SharedLibrary DLL). Same problems.</p>
  
  <p>And yes, I've seen all the posts about how easy it is to create one. It's very easy to create a bad one, but not so easy to create one that looks and works like the <code>SplitButton</code>s in Outlook or Visual Studio, where the drop-down menu doesn't disappear if you release the mouse button.</p>
  
  <p>So, here's my question: Are there any commercial-grade <code>SplitButton</code>s out there, either open-source or commercial, that work in toolbars? I'm not looking for a control that is part of a $1,500 annual subscription to somebody's controls library, but if there is a reasonably-priced <code>SplitButton</code>, I'd sure like to find it.</p>
