Question

I have a StackPanel with a list of custom user controlls that I would like to resize. I would like the user to be able to drag a slider and scale the control size up and down.

Is there a way to bind the control width to a slider value? Something similar to:

<MyControl Width='{Binding Path=SizeSlider.SelectedValue}'/> 

Is this possible? Or should I just iterate through the controls and manually set the size whenever the slider value changes?

You should be able to do this just fine by using

<MyControl Width='{Binding ElementName=SizeSlider, Path=Value}'/> 

By only setting Path you assume that something named SizeSlider would exist in the current DataContext.

I’ve done this in code once and it worked:

var binding = new Binding('Value') { Source = slider }; BindingOperations.SetBinding(b, WidthProperty, binding); BindingOperations.SetBinding(b, HeightProperty, binding); 

So apparently

<MyControl Width='{Binding Source=SizeSlider, Path=Value}'/> 

might be another way to do it.
