How to ignore all user interaction until a specific EntranceThemeTransition finishes? (c#)

Question

I have a popup that enters screen with animation, but user may want to speed up the process and click wildly to the popup, that may dismiss the popup (which i don't want).

1) Can i disable FULL user interaction with the application?

2) Can i detect the end of the EntranceThemeTransition?

Answer 1

I think you need to look into these properties:

IsDoubleTapEnabled	Read/write	Gets or sets a value that determines whether the DoubleTapped event can originate from that element. (Inherited from UIElement)
IsHoldingEnabled	Read/write	Gets or sets a value that determines whether the Holding event can originate from that element. (Inherited from UIElement)
IsRightTapEnabled	Read/write	Gets or sets a value that determines whether the RightTapped  event can originate from that element. (Inherited from UIElement)
IsTapEnabled	Read/write	Gets or sets a value that determines whether the Tapped  event can originate from that element. (Inherited from UIElement)

If you want to do this like a blanket you can add a grid or something else that covers all of your elements and set these values to false, and put the grid inside of a canvas so you can set the z-index of the grid to a higher value than the rest of your application.

I don't see any events that fire when the EntranceThemeTransition ends, but you might try experimenting with the Loaded event of your controls.

Thank you for your reply.

I think i understood the first part of your message.

I tried the second part: Playing with the controls' and also particular element's "Loaded" events.

They are called immediately. I also tried LayoutUpdated to check the animated value (this.GetValue(Canvas.LeftProperty)) but it's already set to the final value right at the beginning-first call. So if i can't detect the end of the animation i can not re-enable everything as i don't want to put a timer by guessing the EntranceThemeTransition 's duration. It may be changed in the future and i'll either re-enable everything before the animation finishes or far after it's end.

Hi,

did you find a method to detect if the application has running/active animations?

I'm touching the same problem in that user interaction should be disabled while element are (animated) added to a container.
The reason is that the user is able to pickup a element and move it over the page. This cause conflicts in that it also updates elements that are still being animated onto the screen.

Greetings and thanks in advance,
