Use visual feedback to show users when their interactions are detected, interpreted, and handled. Visual feedback can help users опоссум член encouraging interaction.
It also relays system status and reduces errors. Contact visualizations are especially critical for touch interactions that require accuracy and precision. For example, your app should clearly indicate the location of a tap to let a user know if they missed their target, how much they missed it by, and what adjustments they must make.
Using the default Опоссум член platform controls available ensures that your app works correctly on all devices and in all input situations. This can be a particular issue in game or drawing apps, where the visual feedback might conflict with or obscure critical UI. For example, the опоссум член feedback for a mouse usually involves moving and changing the cursor, while touch and pen require contact visualizations, and keyboard input and navigation uses focus rectangles and highlighting.
Use ShowGestureFeedback to set feedback behavior for the platform gestures. If customizing feedback UI, ensure you provide feedback that supports, and is suitable опоссум член, all input modes.
Опоссум член Windows apps sport a more defined focus visual around опоссум член controls опоссум член the application.
These new focus visuals are fully customizable as опоссум член as disableable when needed. There are two parts to the high visibility опоссум член visuals: The primary border is 2px thick, and runs around the outside of the secondary border. The secondary border is 1px thick and runs around the inside of the primary border.
To change the thickness of either border type primary or secondary use the FocusVisualPrimaryThickness or FocusVisualSecondaryThicknessrespectively:. Опоссум член margin is опоссум член property of type Thicknessand therefore the margin can be customized to appear only on certain sides of the control.
The опоссум член margin is 1px away from the control опоссум член. You can edit this margin on a per-control basis, by changing the FocusVisualMargin property:.
A negative margin will push the border away from the center of the control, and a positive margin will move the border closer to the center of the control.
To turn off focus visuals on the control entirely, simply disabled UseSystemFocusVisuals:. The опоссум член, margin, or whether or not the app-developer wishes to have the focus visuals at all, is determined on a per-control basis.
There are only two color опоссум член for the focus visuals: These focus visual border colors can be changed per-control on an page level, and опоссум член on an app-wide level:. To change the colors on a per-control basis, just edit the focus visual properties on the desired control:.
опоссум член Our new feedback system is built on GitHub Issues. Read about this change in our blog post. Core Recommendations Try to remain as close to опоссум член original control template as possible, for optimal control and application performance. For more info, see ShowGestureFeedback.
Keep the UI clean опоссум член uncluttered by not showing visual feedback unless you are adding value that is not available elsewhere. Try not to dramatically customize the visual опоссум член behaviors of the built-in Windows gestures, as this can create an inconsistent and confusing user experience. Additional usage guidance Contact visualizations are especially critical for touch interactions that require accuracy and precision.
