Question

That’s me again with my bindings 🙂

Here is the problem, I need to have on my GRID two controls connected with a LINE. So I can move with mouse one of the controls around GRID and LINE, that connect this two controls must replace immediately while moving.

Any ideas? I thought that calculate new X1,Y1,X2,Y2 of the LINE on every 1px move impossible and very speedless… So I think that there is the way to create BINDINGS for LINE’s X1,Y1,X2,Y2, such as:

x1={Binding firstCtrl.Position.X+firstCtrl.Width/2}

But such binding is very hard (for me) even in XAML, but I need to create such binding dynamically in C# code.

Need your advice again, how to create such binding in C# or there is another way to realize my idea?

P.S.”I don’t need whole code for that, just description and, maybe, simple example of code.”

Thanks a lot.

You could use a MultiValueConverter to gather the points of interest and return the X or Y point as needed.

Here is a good blog post discussing their use.
