I have an application that is made using WPF, i have multiple pages and a form that contains a frame, and i load the pages on a frame, and each page has back and next buttons.
what i want to do is to animate the navigation of the pages on the frame in a way when i press Next, the current page slides to the left and the following page slides also to the left and replacing the the current page, and when i press back the current page slides to the right and the previous page slides to the right replacing the current page.
how to do that?
I may be proven wrong here but I don't believe WPF exposes a way to implement this easily. There are methods for overriding existing transition animations in UWP.
For WPF you can handle this one of two ways...
Start the animation of the page sliding out. When the animation is complete let it fire an event that will then call frame to change pages.
Have the page offset by default and perform the animation to slide it in to it's original spot.
or....
Capture the Navigating event of the frame, monitor NavigationMode, call the animations, make the navigation wait or mark e.Handled == true and recall it after with a flag that says it can continue.
Do the same for transitioning in.
Here's the problem; you won't have both pages on the screen at the same time and you'll have to write some fancy transitioning code to make all this work correctly. I would go as far as introducing custom controls with interfaces or DependencyProperties that have the transitioning functions embedded etc.
That said; I have had this problem in the past and to be fair I just gave up on the Frame control and pages and did it all manually. In the end it felt faster, easier to maintain, and I was able to achieve any effect I wanted.
So if you want my honest answer just don't use Frame and do it all manually... (This is speaking for WPF only. UWP has other features and more reasons to use the built in navigation than WPF does.)
