Create a borderless form in 01.WPF

[Citation:]http://blog.csdn.net/johnsuna/article/details/1893319

As we all know, in WinForm, if you want to make a borderless form, you can set the FormBorderStyle property of the form to none to complete.
If you want to make an alien form, you need to use a picture or custom draw with GDI +.

So, in WPF, how do we make a borderless form?

The answer is to set the window's WindowStyle property to None, which is windowstyle= "none". If the non-rectangular shaped form, you need to set the background to Null, will allow transparent set to true, that is: background= "{x:null}" allowstransparency= "True", some people may also want this window can be dragged to drag, then , you also need to set the MouseLeftButtonDown event, such as: mouseleftbuttondown= "Dragwindow", here Dragwindow by the window DragMove () to complete. Want to close the window? Then make a button yourself and then use the close () method of the window itself.

Here are the effects:

There's a circular X button in the upper right corner, which is made with a button, but it's styled as a rounded rectangle. See below for specific code:
XAML Code:

<window x:class= "Borderlesswindow.window1"

Mouseleftbuttondown= "Dragwindow"

</Style>
</Window.Resources>
<!--content in a form--
<Grid>
<!--
The border of the form, the background setting, note that the Cornerradius is consistent with the setting of the "X" fork button in the upper-left corner or about greater than the fork buttonradiusx/ySettings-
<border cornerradius= "10,10,10,10" background= "Orange" height= "Auto" borderbrush= "Teal" borderthickness= "1" > </Border>

<!--the "X" fork button in the upper-left corner--
<button name= "Button1" style= "{StaticResource buttonstyle}" click= "CloseWindow" width= "All" height= "all content=" X " Horizontalalignment= "Right" verticalalignment= "Top" margin= "3,3,3,3" ></Button>

<button height= "margin=" 96,101,121,0 "name=" Button2 "verticalalignment=" Top ">test button</button>
</Grid>
</Window>
