In other words, if a user paste in an image that’s 2MB, we want to automatically shrink it down to a more manageable size. We ha...

I have a template for my list box item. It includes an image button. The button changes images when you hover. The problem I'm having is it's adding a weird artifact to the button when I hover. This ONLY happens though if it's in a ListBoxItem. If I put the button on the main canvas, it works fine. Here is the image in the normal state...
I have seen that in Blend you can see which properties have been changed and use the reset option to get back to default values. Is there any other way of finding what the default values of a control are? JD ...

During validation, I may find out there is another control in the window I need to validate. I know only the field name in the Da...
I have been looking into MVVM recently and I seem to get the overall idea. There are a couple of niggly bits though that I do not fully understand and was hopping to get some answers here, cheers! Is it incorrect to use one data model for the whole application. Usually if I am creating a small utility I would have all of the logical da...
