Silverlight-通过可见性进行动态绑定

Question

If I have two text boxes, one is visible , other one isn't . Both are bound to the same property.

Is there a way to bind only visible one? That way validation causes only one error in the Validation Summary ?

I have a form with many fiends but also many different ways people can enter data based on their selection. So I was wondering if there is a way of maybe having a method that goes over all hidden components and disables validation or/and unbinds it temporarily .

Here's a nice short example of what you're trying to accomplish: http://blog.dotnetstep.in/2009/12/silverlight-3-enable-and-disable.html

You could use the visual tree walker in this example to walk the visual tree and remove the bindings on any framework elements who have a visibility value of collapsed: http://netpl.blogspot.com/2010/03/silverlight-visual-tree-walker.html
