❔ wpf styling/templating with custom dependency properties?

is there a way to use custom dependency properties with styles and templates?

for example

if I want a property, MiddleColour, on a template for a slider, that changes the background colour of the middle bit of the slider
and I want to be able to change that colour using a style.
Is that possible?

Continuing on,
would it also be possible to pass a property to the style, eg GradientColour, which is then used and passed to the MiddleColour in the template?

Thanks

you can customize the visuals of a control by providing it a custom ControlTemplate

and in theory, I think you could define your property as an attached property, and be able to bind to that from within the template

not entirely sure what you're asking with the second question

with the second question, so the MiddleColour is a brush, but i'd like a style that gives it a gradient brush that goes from #000000 to a given colour GradientColour

well, that is a thing you can do with brushes

lucyOP•8/26/23, 8:39 PM

yes, but i'm asking specifically is there a way to get it so you have the compnent, give it a style, give it a GradientColour, and the style handles translating GradientColour into a gradient brush

rather than having to pass in a unique brush for each colour you want to use as a gradient

for example

yeah, that should be doable, assuming what I said earlier is doable

with being an attached property

and with that being inside a you'd have that be a
