New Post: (WPF4+ Prism4) How to use InvokeCommandAction ?

fmartinez,

Sorry, I cannot rebuild the senario.

But I guess that may be there are some incompatibility between Nuget packages Blend.Interactivity.WPF.v4.0 and Blend.Interactivity.WPF.

In my solution, some projects reference Nuget package Blend.Interactivity.WPF.v4.0 and some use Blend.Interactivity.WPF and some use both. I guess it IS the source of
problem. After I only reference Blend.Interactivity.WPF.v4.0, the program is OK now and I do not know how to rebuild the scene.

Install Blend.Interactivity.WPF.v4.0, Blend.Interactivity.WPF and uninstall them in different sequences will show some Phenomenon strange to me.

Why I want use InvokeCommandAction?

1. After I replace Button with TextBlock, Content with Text, and Click with MouseDown, every thing is OK as expected.
2. When program is running, if I press arrow key DOWN, the selected treeview leaf changed. I try to use this feature to raise event. (because use arrow key is more convenient than mouse in my project).
3. I modify TextBlock with property Focusable="True" and replace MouseDown with GotFocus, but this DO NOT work. I am still trying to solve this problem.
   

Hope you can help me.
Thanks
