This is not a
problem, you're just stuck defining the logic of your project. What you need is known as Binding, apart from data binding, you can bind properties of one control to other; such as Value of on Slider to the Value property of other Slider and so on.
Before you continue, please read the documentation about
Data binding on MSDN[
^], they would provide you enough underlying understanding of what this is in real, when you should use it, and what does it provide you with. You will be in a good company on MSDN documentations.
You can understand how to do this, from this example of mine. I will use 2 sliders (not 20) and I will bind value of second, to the value of first one. Look below,
<Slider Name="slider1" Minimum="0" Maximum="100" />
<Slider Value="{Binding ElementName=slider1, Path=Value}" Minimum="0" Maximum="100" />
Now when you will change the value of first slider, the value of the second one would change automatically; because it is now bound to the
slider1. Learn more about
Slider controls on MSDN[
^]. You can then use the same mechanism to bind other controls to each other.
