Hi,
I just gave you sample a try.
But this does nothing than setting the grid's opacity.
So when IsBusy changes to false the indicator goes away btt the grid stays opaque.
This is of course not a solution for my needs.
What I want is a busy indicator that shows an animaton and blends my UI to show the user that he has to wait.
You inicator does this as expected - as long as I don't change any colors. Neither via custom theme colors, nor by setting a controls foreground.
Of course I could write "code behind" to achive this, but from my point of view this is what the indicator should do by desing.
And again - it is doing it for default colors.
So not doing it for custom colors looks like a bug for me.
I found a workaround like this
This is just a simple workaroung (of course the borders background should be dependant from the theme (main background), but at least it works.
Although it still shines a bit more on custom colors since your control somehow (from code) tries to blend default colored elements.
Anyhow - I can work whith this solution.
