How to do calculation in xaml while binding?

I can bind a label to a slider as shown below:

<Label Name="lblTest" Content="{Binding ElementName=slider1, Path=Value}"/>

How do I bind another label to the same slider with display value of, say, 30% of the value of slider? How do I do the calculation in xaml and not in my code? Thanks.

There are already a few projects which bring expressions to Bindigs, e.g. see CalcBinding or QuickConverter.

You cannot do the calculation in XAML, you could however apply some converter which does it for you.

This question might be relevant: How do you change a bound value, reverse it, multiply it, subtract from it or add to it?
