WPF - Generate BitmapSource from Over state of a button
I can generate a BitmapSource
from a button fine, however it always is just the image of the normal state of the button.
I want to be able to generate a BitmapSource
of the over state of a button.
I tried calling
VisualStateManager.GoToState((FrameworkElement)target, "MouseOver", true);
before calling my code to generate the BitmapSource. It correctly changes the button 开发者_开发百科to the overstate on the GUI, but the BitmapSource
is still that of the button in the normal state.
I figured out the problem. VisualStateManager.GoToState((FrameworkElement)target, "MouseOver", true);
just begins the transition to the specified state. I needed to give control back to the UI thread and wait for the state to actually change before trying to save the bitmap.
