A bit new with WPF...It seems like not matter what I change with horizontal and vertical alignment, WPF has a mind of its own when resizing my controls in design time. I created a new Window, placed a couple of buttons and text boxes and whenever i change the size of the window all the controls get resized. Is there a way to lock it do...

Hello - I am wondering if anyone has attempted the following or has an idea as to how to do it. I have a WPFToolkit DataGrid which is bound to an ObservableCollection of items.

I have a custom part based off of a UserControl but there is no way in WPF to do : [Import]<my:SomeCustomControl> so the cascade doesn't work in this instance. /Edit I am having an issue [Import]ing...

I'm trying to learn WPF and the MVVM problem, but have hit a snag. This question is similar but not quite the same as this one (handling-dialogs-in-wpf-with-mvvm)...
