Question

Answer 1

A:

<UserControl Canvas.Left="{Binding Text, ElementName=myFirstTextBox, Mode=TwoWays}"
             Canvas.Top="{Binding Text, ElementName=mySecondTextBox, Mode=TwoWays}"  ... />

But I can only strongly recommend you to use some sort of custom ValidationRule on your TextBoxes, in order to disallow any input that does not represent a valid number, otherwise you will get a nice crash.

Alternately, you can also bind from Text on your text box to {Binding (Canvas.Left), ElementName=myUserControl, Mode=TwoWay}

Thanks Aurelien, I thought that would be more complicated.

Thank the magic of WPF. Coming from the Java world, it is impossible to go back :)
