I am aware of the following question:
I want to disable the shadow effect on a specific aero window
However, I still need the DWM blur/reflections behind my Aero window, so I can't create a custom transparent one. How would I approach that? I could handle the reflections by myself, but I don't know how to create a blur.
Done it using DwmEnableBlurBehindWindow. :)

out current application is a DevExpress Ribbon window. However, we have some legacy code - including a WPF Control which was hosted through a WinForms Window - with WPF Host. (please dont ask why)
I wanted to change the UserControl at least to a Wpf Window to get rid of WinForms.
Now here is my Problem: All stlyes get totally messed up. Especially my buttons have a problem:
The buttons lose their assigned Images, and also Background and Foreground is not assignable. Through the Live Visual Tree from Studio I see that it is overridden.
I guess the thing with images leads to the same root cause.
I dont want to redo the whole window again in DevExpress (if this is the cause).
Is there a way for a window to not use some application styles and run as default? Or how can I find out, what is actually overriding everything?
I finally found the solution. The DevExpress was overriding any styles of any form in application, settings something to the DevExpress.Xpf.CoreTemeManager.
To disable a style, I had to add the following thing to my window:
<Window x:Class="AnotherWindow"
xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core"
dx:ThemeManager.ThemeName="NoneName"
<!-- ...-->
</Window>
Also include DevExpress.Data and DevExpress.Xpf.Core references.
Here's what I am trying to accomplish - To create an MDI application in WPF, which can host child web applications. I am using WPF webbrowser control to render web applications. WPF inherently doesn't seem to support MDI applications, so after a bit of searching, I found this project, which uses UI controls to simulate windows and manages them inside a WPF canvas. This approach seems to work reasonably well until I start adding webbrowser control object as an MDI child.
When I add webbrowser control as an MDI child, it always appears on top of other WPF elements including other MDI child controls (as shown below). From what I understand, webbrowser control always appears on top of any other WPF object except for window (and popup). Assuming that's true, I think I need to use actual WPF window to avoid overlapping issue.
The only solution i can think of right now is to wrap WPF window inside an HwndHost object and then add that as an MDI child. However it appears that a child window cannot have title bar. That means that i need to have a window that has a dummy title bar area (just like actual window title bar) and actual content area (which will show webbrowser control) as shown below (Red border is HwndHost object).
This approach seems to solve the overlapping issue. The next thing i need to try is to let users click on the dummy title bar and drag the MDI window inside the canvas element.
Questions -
Is my understanding about WPF webbrowser control overlapping behavior right? If not, what am i missing?
Is the second approach a step in right direction for accomplishing what i want? If yes, how do i implement the drag behavior for HwndHost?
Is there any other alternate solution i can try?
Note:
Although many consider MDI not an elegant solution, I do not have a choice. (We tried alternate solutions like tabbed windows/dockable
windows, but were not well received)
I am quite new to interop programming, and do not understand the
concepts well. Please correct me if i am misunderstanding things.
Thanks!
I'm not sure that's the right way to say it, but what I want is to for my wpf main window to have it's own bar that will behave like a taskbar, and any children windows that will be open from the main one will be placed in that bar in a similar way like the taskbar works in windows - a rectangle showing the window name for example, on click it opens you the window, if you click minimize it will minimize it to the bar, and with some option, to get it out of the main window and move it to the real windows taskbar, with another option for putting it back in. The problem is I don't know if this is even possible, and I don't know the name of such an element, so if anyone can give me any tips I'll be really thankful.
I worked on an application years ago (.NET 3.0: first WPF release!) that did exactly that. We ran into a lot of issues getting it to work, but we were pretty successful in the end. One thing we didn't support was moving it to the Windows taskbar.
The best option would be to set an attached property on each Window. This would register a Window with your custom taskbar, so if you wanted to move the Window out of your custom bar, you'd set the property to false. Setting the property to true would add it to the collection of application windows, as well as register event handlers to track the state of the Window.
One of the major pain points for us was getting the Window animations correct. If you're not running in XP, this probably less of an issue, as the animations in Vista (or is it 7?) and above aren't really showing where a Window is going on minimize. In the end, we had to do a lot of low level Win32 (p/Invoke) work for this.

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.

How to create custom window chrome in wpf?
(5 answers)
Closed 6 months ago.
We are developing a WPF application which uses Telerik's suite of controls and everything works and looks fine. Unfortunately, we recently needed to replace the base class of all our dialogs, changing RadWindow by the standard WPF window (reason is irrelevant to this discussion). In doing so, we ended up having an application which still looked pretty on all developer's computers (Windows 7 with Aero enabled) but was ugly when used in our client's environment (Terminal Services under Windows Server 2008 R2).
Telerik's RadWindow is a standard user control that mimicks a dialog's behaviour so styling it was not an issue. With WPF's Window though, I have a hard time changing its "border". What I mean by "border" here is both the title bar with the icon and the 3 standard buttons (Minimize, Maximize/Restore, Close) and the resize grip around the window.
How can I change the looks of these items:
Title bar color
3 standard buttons
Window's real border color
With round corners if possible.
Those are "non-client" areas and are controlled by Windows. Here is the MSDN docs on the subject (the pertinent info is at the top).
Basically, you set your Window's WindowStyle="None", then build your own window interface. (similar question on SO)
You need to set
WindowStyle="None", AllowsTransparency="True" and optionally ResizeMode="NoResize"
and then set the Style property of the window to your custom window style, where you design the appearance of the window (title bar, buttons, border) to anything you want and display the window contents in a ContentPresenter.
This seems to be a good article on how you can achieve this, but there are many other articles on the internet.
I found a more straight forward solution from #DK comment in this question, the solution is written by Alex and described here with source,
To make customized window:
download the sample project here
edit the generic.xaml file to customize the layout.
enjoy :).
Such statements as “you can't because only Windows can control the non-client area” are not quite true — Windows lets you specify the dimensions of the non–client area.
The downside is this is only possible by calling Windows' kernel methods, and since you're in .NET, which is not native code, you'll need P/Invoke. (Remember, the whole of the Windows Form UI and console application I/O methods are offered as wrappers that make system calls under the hood.) Hence, as documented in MSDN, it is completely possible to use P/Invoke to access those methods that are needed to set up the non–client area.
Update: Simpler than ever!
As of .NET 4.5, you can just use the WindowChrome class to adjust the non-client area. Get started here and here, a guide to changing the window border dimensions. By setting it to 0, you'll be able to implement your custom window border in place of the system's one.
I suggest you to start from an existing solution and customize it to fit your needs, that's better than starting from scratch!
I was looking for the same thing and I fall on this open source solution, I hope it will help.
