I have some quite complex content behind several tabs. I'd like to force the layout to happen at application startup rather than lazily as the user clicks a tab for the first time. The delay is about a second or two per tab, and it's a bit embarrassing!
Edit: I think the problem is that only the selected tab's content control is in the visual tree. Calling ApplyTemplate of the HeaderedContentControl didn't make any difference.
Does this link help you?
wpf force to build visual tree
Basically it says to use ApplyTemplate on the ItemsControl...I guess that for the tabs you should do it for each TabItem.
There's also another technique used in this site:
http://xcalibur37.wordpress.com/2012/07/12/make-your-tabcontrol-preload-in-wpf-silverlight/
Here he creates a kind of preloader for each tab. It's for silverlight but I think it can be applied to WPF.
Hope it helps out :)

I'm a WPF newbie and, unlike WinForms, I have a hard time to setup things in the design window.
My first obstacle is the Image control. After I drag it in the Design window it disappears and there's no way for me to edit its properties (like with the button control for example). The only way to make changes is via the XAML code which isn't very visual and intuitive.
Is there a way to keep editing the Image control in design mode? (example, move it around, select it to view its property panel, etc.)
All you should need to do is give the image control a fixed height and width and it should stay in the designer.
The best thing about the XAML is which separated from code for better re usability like asp.net. It's best you to learn different layouts such as grid, wrappanel, stackpanel etc. Then, you will feel the power of xaml. Else, you can choose the XAML building tools.

I'm trying to build an app in winforms with something similiar to masterpages in asp.net - a menu on top and when choosing an option from the menu the entire screen on the bottom will change while the menu remains (there are 10-15 screens in the future app, some are quite similar, some are not).
What is the best way of doing this? Should I use different forms for each screen or use a panel or something else?
If I use a panel or something how do I manage to use the designer with so many panels taking space on the screen?
Try with the MDIParent Form's. View the Example

If it is just keeping the same menu and opening/closing parts of the UI you could simply add and remove instances of usercontrols to the main form.
If you need more features such as docking (like Visual Studio) look at this
Another option is to use Form inheritance
Which one to select depends on what you want to reuse and the features you need.
One option would be to make your application an MDI window and then load entire forms, maximized, into the parent window.
Then, you would be able to treat each form as its own self-contained item, since it really would be exactly that.
Is it not an option for you to use WPF? A WPF browser application fits the paradigm you are describing quite well.
Am looking to implement a detach and popup UI behaviour in my applcation.
It basically means that I will be displaying say, a stackpanel with lot elements on the right side of my page. And on a button click, I want the stackpanel part to popup(removing its allocated space in the UI) and should be able to move it above the underlying wpf UI.
What am trying to do is that remove the stackpanel from its parent grid on button click and add it as the child of wpf popup control. But I am facing some issues doing this way. However I just want to know whether I am doing it in the correct way or do anyone have a good alternative for implementing this pin out functionality am specified here?
Thanks,

How about using this kinda nice control, AvalonDock, which is simulating Visual Studio's dockable components behaviors?

It will spare you the pain of developing such a specific functionality, and will have a great reusability anyway
I need a toolbar button similiar to the "New Project" button in the standard Visual Studio toolbar. When clicked, it pops up a dialog. However, it also has a small little down-arrow next to the icon graphic that, when clicked, expands a context menu with more options.
Is there a standard control available with this functionality?
I don't think there's built in functionality for a SplitButton in WPF currently. Here's another thread that may help you out though:
WPF SplitButton?
You could combine a couple of controls together to make one fairly quickly. Might as well make a new UserContol out of it that can be re-used throughout your app as well.
Also, a quick search on WPF SplitButton will return a lot of examples on how to make one or you could get one off of CodeProject or CodePlex (though I'm not sure if they'll come with a image property automatically).
I don't know what this is called in SL, but I would like to replicate this functionality. If you go to this site: http://www.mscui.com/PatientJourneyDemonstrator/PrimaryCareAdmin.htm and click on the "Show Details" button located on the top, right-hand corder of the screen. When you click on this, there should be a "Scene Details" button-like feature on the right side. When you click on this, this is what I would like to implement. Can someone direct me please? Either to an online article, etc...
I'm not precisely sure what feature of the site you'r referring to (I'm blind so the description doesn't make much sense to me). However, two useful links - some of the MSCUI source code is available on Codeplex http://mscui.codeplex.com. Also, the Silverlight developer/designer on this project created Blacklight http://blacklight.codeplex.com which includes visual assets to use with Silverlight.
Although I don't know the specifics of the implementation, as far as I can guess, this is done by having a second Grid that follows the Grid for the page. Then, simply change the visiblity on the "guide" grid when the button toggles.
I believe that is simple, although it'll require you to work to figure out the positioning of the underlying page - but it's more flexible. With Blend it'll be easy.
Alternatively you could have a ton of additional UI elements on the page next to their respective controls, and either Tag or name them in a way that you can iterate over them to control visibility and interaction.
I think you're talking about a the grey overlay with a modal window on top. I think the best way to do that in Silverlight 3 is with the ChildWindow control.
