Is it possible to remove the white strip on top of WPF window with Window Style=None. XAML and Window is shown in the screenshot:
What you are seeing in white is the re-size border. You can remove that and still make the window resizable by setting ResizeMode="CanResizeWithGrip" AllowsTransparency="True"
If you dont want to resize at all then do this - ResizeMode="NoResize", again you wont see the border but you cant resize.
<Window x:Class="HandsOnSolution.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Background="Green" WindowStyle="None" ResizeMode="CanResizeWithGrip" AllowsTransparency="True">
<Grid>
</Grid>
</Window>
Edit
Good point by #devuxer, if you are interested in dragging you can add this piece of code to the window mouse down event
<Window MouseLeftButtonDown="Window_MouseLeftButtonDown"/>
//code behind
private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
I had been hunting for a solution for a couple of days now, in simple words this link held the answer to my queries
though the code snippet that did the magic was:
<Setter Property="WindowChrome.WindowChrome">
<Setter.Value>
<WindowChrome CaptionHeight="0"
CornerRadius="2"
GlassFrameThickness="0"
NonClientFrameEdges="None"
ResizeBorderThickness="3"/>
</Setter.Value>
</Setter>
I just added the above property setter to the custom Window Style.
Hope that helped :)
A much simplified code, acting on only one property:
<WindowChrome.WindowChrome>
<WindowChrome CaptionHeight="0"/>
</WindowChrome.WindowChrome>
I added this piece of code:
<WindowChrome.WindowChrome>
<WindowChrome GlassFrameThickness="0,0,0,1" CornerRadius="0" />
</WindowChrome.WindowChrome>
inside <Window> paste here <Window/> and it helped :)

this is in XAML Designer
Expected:
Actual:
This is my window's XAML:
<Window

</Style>
</StackPanel.Resources>
<Button>测试</Button>
<Button>测试</Button>
<Button>测试</Button>
</StackPanel>
<Canvas Height="2" Background="Red" />
</StackPanel>
There is extra space around the window.
I found that as long as the height is less than 40, there will be extra space.But I didn't set minHeight.
this is my app.xaml:
<Application x:Class="WpfApp2.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApp2"
StartupUri="MainWindow.xaml">
<Application.Resources>
</Application.Resources>
my environmental information:
Windows 11
Visual Studio 2022
.net framework 4.8
In WPF SizeToContent does not work very well with WindowStyle=None. It seems the renderer is still taking a non-existant border into account when initially drawing the Window.
A simple hack to overcome this: set Height="1" on the Window to force its initial size to something smaller than the eventual size. Then when the content is rendered, SizeToContent="WidthAndHeight" will cause the window to resize itself to the correct size.
I just started working with WPF and want to create a simple app.
However, when I place buttons at the bottom of the window and launch the app - they get cut off
Has anyone encountered this problem?
Designer preview shows this
But then when launching the app button gets cut off
XAML code is as follows:
<Window x:Class="DXF2SVG.MainWindow"

<Button x:Name="btn_LoadDXFFile" Content="Load .dxf File" Width="100" Height="40" Canvas.Top="334" Canvas.Left="150" />
</Canvas>
</Window>
Thanks in advance!
Everyone who said canvas is evil is right
#NawedNabiZada 's answer about grid and vertical and horizontal alignment did the trick
thanks everyone!
I am creating a WPF application and want my window to be borderless, and also possible to be resized only from the top.
What I have tried so far
I initially thought this would work:
<Window x:Class="WpfApplication3.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Width="200" Height="150"
WindowStyle="None"
ResizeMode="CanResize"
AllowsTransparency="True"
BorderThickness="0,5,0,0"
BorderBrush="Black">
<Grid Background="Gray" />
</Window>
I do get a window with top border only, but I cannot resize it.
Then I tried WindowChrome.ResizeGripDirection="Top" with ResizeMode="CanResizeWithGrip".
<Window ...
WindowStyle="None"
ResizeMode="CanResizeWithGrip"
AllowsTransparency="True"
WindowChrome.ResizeGripDirection="Top"
BorderThickness="0,5,0,0"
BorderBrush="Black">
...
</Window>
This does not work either (unable to resize from top border), and the grip does not even appear on top. It stays on the bottom-right corner (I can resize with the grip, though).
This answer seems like the answerer may initially have done this, but the code is unavailable.
This answer has a link to a blog post, I am not too eager to try it because I would like a solution without code behind.
And then there is this answer:
I get an error with this approach:
<Window ...
WindowStyle="None"
ResizeMode="CanResizeWithGrip"
AllowsTransparency="False">
<Grid Background="Gray" />
<Setter Property="WindowChrome.WindowChrome">
<Setter.Value>
<WindowChrome CornerRadius="0"
GlassFrameThickness="1"
UseAeroCaptionButtons="False"/>
</Setter.Value>
</Setter>
</Window>
The property 'Content' is set more than once.
With code behind:
<Window ...
WindowStyle="None"
ResizeMode="CanResize"
AllowsTransparency="False">
<Grid Background="Gray" />
</Window>
In constructor:
WindowChrome chrome = new WindowChrome();
chrome.CornerRadius = new CornerRadius(0);
chrome.GlassFrameThickness = new Thickness(0, 1, 0, 0);
chrome.UseAeroCaptionButtons = false;
Which gives me:
And this could be resized from all directions. And I only want it to be able to resize from top. (Surprise: I did not even assign the new chrome object to anything. How did that work? That's another question I guess).
Question
How do I make a borderless window which can only be resized with the top border? (It's best if I can do this with only a top border whose color could be changed).
You may have success setting the WindowChrome.ResizeBorderThickness property to remove all borders except the top, e.g. ResizeBorderThickness="0, 5, 0, 0".
It may not be the cleanest way to achieve your result, but I've had some success adapting the answer here: http://www.eidias.com/blog/2014/1/27/restyle-your-window (it was the easiest way I found to get WindowChrome working):
Create a custom window style in a ResourceDictionary:
<ResourceDictionary x:Class="WpfApplication.WindowStyle"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="CustomWindowStyle" TargetType="{x:Type Window}">
<Setter Property="WindowChrome.WindowChrome">
<Setter.Value>
<WindowChrome CaptionHeight="30"
CornerRadius="4"
GlassFrameThickness="0"
ResizeBorderThickness="0, 5, 0, 0"
UseAeroCaptionButtons="False" />
</Setter.Value>
</Setter>
<Setter Property="Window.BorderThickness" Value="0, 5, 0, 0" /
</Style>
</ResourceDictionary>
Reference the dictionary where required (I put it in App.xaml):
<Application x:Class="WpfApplication1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary Source="WindowStyle.xaml" />
</Application.Resources>
</Application>
Reference the Style in the required Window:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525"
Style="{StaticResource ResourceKey=CustomWindowStyle}">
<Grid>
</Grid>
</Window>
That should produce a window that looks like your final one, but can only be resized from the top (only the top resize handle can be grabbed).
I am trying to create my own expandable/collapsible menu (creatively called ExpandingMenu) in my first WPF project. I already have one user control consisting of a 2-row Grid (row 1 is a button to collapse and expand the control, row 2 is a StackPanel for rotating ToggleButtons, which is where I'm currently stuck). For my rotating buttons, I have just decided to make them their own UserControls as well.
The Buttons (I'm calling them ExpandingMenuButtons) are no more than a ToggleButton in a 1x1 Grid (I'm thinking of doing it this way since I may want to add some extra custom logic to these buttons after I get the standard behavior sorted out). I can add them to my menu control successfully, I can even get them to rotate via a RenderTransform on the Grid.
However, as you can probably tell, they swing up when they rotate. This causes them to not only be too high, but they also likely extend to far up.
This is what I currently have, before attempting rotations, it is behaving as expected.
This is what I'm trying to accomplish (edited using the magic of paint). I can get this correct behavior in my Menu control (tan areas), but I've mangled the expand/contract event in the meantime for testing purposes...
What I can do when I rotate 1 button (Like I mentioned earlier, I've mangled some behavior for my testing purposed, so each button is set to rotate on click, not all at once like you may expect). As you can see, this button has swung out from where it originally was. buttons higher up will swing partially/completely out of view. Instead, I would like them to rotate into the proper place. once I get one to work right, I assume it will be simple to get the rest behaving the same way, which I why I'm trying things this way..
My button code is below:
<UserControl x:Class="App.Controls.ExpandingMenuButton"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:App.Controls"
mc:Ignorable="d"
d:DesignHeight="30" d:DesignWidth="100">
<Grid Name="ButtonGrid" Height="30">
<ToggleButton Name="MenuButton" Background="Aqua" BorderThickness="0 0 0 1" Click="MenuButton_Click" Content="TEST"></ToggleButton>
</Grid>
</UserControl>
the only "real" code in ExpandingMenuButton.xaml.cs so far:
private void MenuButton_Click(object sender, RoutedEventArgs e)
{
//I know this is not practical, it is used for quick testing.
ButtonGrid.RenderTransform = new RotateTransform(-90);
}
My menu code so far:
<UserControl x:Class="App.Controls.ExpandingMenu"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d"
Name="ucExpandingMenu"
MinWidth="32"
d:DesignHeight="300" d:DesignWidth="100">
<UserControl.Resources>
<SolidColorBrush x:Key="BackColor" Color="PeachPuff"/>
<!-- This style is used for buttons, to remove the WPF default 'animated' mouse over effect. http://stackoverflow.com/a/4182205/2957232 -->
<Style x:Key="ExpandButtonStyle" TargetType="Button">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Name="border"
BorderThickness="0 0 0 1"
BorderBrush="Black"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="BorderBrush" Value="Black" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<StackPanel Name="MenuPanel" Width="100" HorizontalAlignment="Left" Background="{DynamicResource BackColor}" Grid.Row="1">
<!--Contents will go here-->
</StackPanel>
<Button Style="{StaticResource ExpandButtonStyle}" Width="100" Height="32" FontSize="18" VerticalAlignment="Center" HorizontalAlignment="Stretch" Panel.ZIndex="1" Background="{DynamicResource BackColor}" BorderThickness="0" Click="Button_Click" Content="»"></Button>
<Button Name="DummyFocus" Panel.ZIndex="0" Height="0" Width="0"></Button>
</Grid>
</UserControl>
And again, the only "real" code in this class so far:
private void Button_Click(object sender, RoutedEventArgs e)
{
MenuPanel.Children.Add(new ExpandingMenuButton("TEST ITEM"));
}
Please excuse my lack of WPF knowledge, I'm trying to come from a world of Winforms, where even there I have a lack of knowledge when it comes to this sort of thing. I know the code looks kinda funny, but hopefully the images show what I'm after here. So far I'm just testing this in a dummy window with only a grid and the HorizontalAlignment set to "Left". Nothing fancy.
Use LayoutTransform. Using RenderTransform does not affect how other controls (including parent) are being rendered/laid out; LayoutTransform does.
Shift the transform to the whole UserControl. You can probably specify directly in XAML instead.
Example:
<UserControl.LayoutTransform>
<RotateTransform Angle="-90" />
</UserControl.LayoutTransform>
I need to use the ToolTip on a label inside a xaml
<Page x:Class="xxx.xxx"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="464" d:DesignWidth="628"
Title="ManagementDetails" Loaded="Page_Loaded">
<Grid>
<Label Margin="0,360,376,91" >
<ToolTipService.ToolTip>
<ToolTip Content="Turtle" />
</ToolTipService.ToolTip>
</Label>
</Grid>
</Page>
this xaml file is used to be a child inside a frame contained in another xaml file
<Window x:Class="xxx.xxxxxx"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="ViewProject" Height="626" Width="810" >
<Grid Height="600" Width="800">
<Frame Margin="172,136,0,0" Name="frame1" />
</Grid>
</Window>
i embedded the page xaml file inside the frame using
MyClass myClass= new MyClass();
frame1.Navigate(myClass);
if i moved the label with the ToolTip from the page xaml file to the window xaml file the ToolTip work but when use it inside the page xaml file it doesn't work.
what is missing here to make it work inside the page xaml file
Why are you doing it this way?!?
Just do something like:
<Label Name="Some_Label" ToolTip="Turtle"> Fun with labels ...</Label>
Done. Should work inside another or by itself.
Using the ToolTip Control:
The ToolTipService class must be used along with the ToolTip control in order to display a tooltip to our control. For the example I will use an image control, but the following can be applied to each of the controls. Here is the code:
<Image Source="GiantSeaTurtle.jpg" Width="400" Height="300">
<ToolTipService.ToolTip>
<ToolTip Content="Turtle"></ToolTip>
</ToolTipService.ToolTip>
</Image>
Thanks guys for all your answers it seems that is was my fault and feel ashamed, i had duplicate xaml files for the same page and i was editing one and viewing another one. Sorry for this inconvenience and thanks again for your help.
