I’m using RibbonSplitButton of the Microsoft Ribbon for WPF and want to open its dropdown when clicked. I tried to catched the clicked button and set IsDropDownOpen=true but the dropdown open then close immediately. How can I retain the dropdown open?

[Edit]
Here is my demo codes to reproduce my problem – I modified the Word sample in the sample downloaded from MSDN’s WPF Ribbon.
My split-button is placed in the file UserControlWord.xaml and located right after the comment

I added a handler for the click event and set the property IsDropDownOpen to true expecting to open the dropdown but it doesn’t – the problem appears as I posted above.
