So I am making a program in wpf using blend that required a sidebar like in the windows 10 xbox app. I have the states and when i press the hamburger icon it expands with a nice slide transition using the GoToStateAction behaviour but how do I make it that when the hamburger icon is pressed while it is in the state of expand it reduces the menu back to the side state. Anyone?

Solution 1

you need to replace your GoToStateAction by something like:

VB

if ExpandedState = True then
    GoToStateAction "Reduce"
    ExpandedState = False
else
    GoToStateAction "Expand"
    ExpandedState = True
end if

I let you deal with details
ExpandedState must be a global variable

If you can't read the state, you can create a variable that remember actual state.
the variable have to persist between calls to this piece of code.
