leovernazza, the problem I’m having is that my Visibility is databound to a data element (the same one that I’ve also bound to my Canvas.Left and Canvas.Top). When that visibility flips from “Collapsed” to “Visible”, I know that there is data on the object (Visible objects require that data), but it hasn’t updated through to the Canvas binding.

The result is that the IsVisibleChanged is handled, but the Canvas bindings haven’t metriculated through to the layout. My solution involved just saying “screw it” to the layout and going to the object directly.

Hey, don’t be afraid of Invoke or (BeginInvoke), it’s actually a very good friend to have sometimes.

Email me if you want to talk about it (or we can get in touch at Mix).

I don’t know if I understand your problem…

object.Left has a databinding
object.Top has a databinding
object.IsVisibleChanged is handled

What if you handle the change of the three properties? Could you?

private void CallInAllChange()
{
if (this.AllChangesWereMade)
{
// do what you need
}
}
