Hi, As I'm learning WPF I came across quite a few examples, but mostly all of them have a disclamer like 'this is not production quality code', as they refer to a specific issue they're addressing. What I would like is to see how is WPF used in reallife, the application as a whole, so that in one example I can see all of the best pract...

I.e. setting validation without setting binding. I am asking because adding regular binded value is an overkill for me (in this particular case) -- I just show a dialog, if user clicked...
Hi all! I have an Image control inside a custom ContentControl that I use to apply some transforms (scaling and translating through the RenderTransform). The problem is that with images bigger than the control's area, if I scroll or zoom out it's all clipped as in the original viewport. Is there a way to force the image to draw itself...
I've a simple WPF app, and I'd like to add what is known in the Win32 world as keyboard accelerators. It looks like KeyBinding is the ticket, but it requires binding to a Command object. I'm not using command objects, nor do I want to. Is there another way to get an event triggered when a ctrl-x key sequence is hit? ...

I have a WPF (.Net 3.5 sp1) application that loads a bunch of data on start up (it takes a few seconds to start up) but it performs fine after the data is loaded. While the app is running, if I don't touch it for some time (say, a few hours), and then I alternate to it, it then "wakes up" very slowly. My questions: 1) Why is that? Is...

So for example if ValueH=1 Fill=Red, ValueH=2 Fill=Blue, ValueH=3 Fill=Green and so on. I have also declared storyboards so that when the value of ValueH changes, a ColorAnimation is run...

Hi, I know the title is really unclear, so give me a moment :) I'm a pro-coder doing cool stuff at work (console games), but I've got an idea for an app (for a couple of years now ;)) that I'd like to create at home. With 15 years of experience, I don't want to fall in to the trap of wanting to do everything myself - I'd like to borrow...
