Currently i am designing WPF application using MahApps.Metro style UI.
Tile control which provided by MahApps can not showing icon in center of tile
I saw example in MahApps website where it could show image as tile background, but I couldn't figure out how to show icon instead of image (icon such as IE logo, people logo, maps logo, etc)
I appreciated if someone can show me how to do this
Thank you
i figure it out
use icons.xaml as resource, and add rectangle control inside tile, here is the example on how to show character inside tile control
<Controls:Tile x:Name="mahTileExit" Background="Green" Foreground="Yellow" Title="Exit" Width="100" Height="100" TiltFactor ="4" Margin="936,404,0,0" VerticalAlignment="Top" HorizontalAlignment="Left">
<Rectangle Fill="White" Height="45" Width="45">
<Rectangle.OpacityMask>
<VisualBrush Visual="{StaticResource appbar_door_leave}" Stretch="Fill" />
</Rectangle.OpacityMask>
</Rectangle>
</Controls:Tile>
thank you if anyone notice about this, hope can help to contribute
You can use FontAwesome.Wpf which has more icons and requires less code.
<Controls:Tile Width="300" Height="150" Grid.Column="0" Grid.Row="1" Title="Hello!">
<Grid Width="50" Height="50">
<fa:ImageAwesome Icon="Flag" Foreground="#FFFFFF"/>
</Grid>
</Controls:Tile>
Don't forget to call the namespace
xmlns:fa="http://schemas.fontawesome.io/icons/"

here I have an image (I want to display it as an icon in my list).
and I have to change its color when it's selected.
I tried this solution before:
https://stackoverflow.com/a/42794551/14564778
With this codes:
<Grid Margin="5,0,0,0">
<Image Height="25" Width="25" Source="{Binding ItemImageSource}" RenderOptions.BitmapScalingMode="Fant"/>
<Rectangle Height="25" Width="25" Fill="{StaticResource orangePink}" RenderOptions.BitmapScalingMode="Fant">
<Rectangle.OpacityMask>
<ImageBrush ImageSource="{Binding ItemImageSource}"/>
</Rectangle.OpacityMask>
</Rectangle>
</Grid>
The problem I got is the shape of the image is not consistent when I apply the new color
Note that the images that I use are high resolution images.
so, If anyone can help me with codes or third-party library or another way.
I will be happy for this.
thx...
I have a StackPanel containing five images and I want to put a black border around each image.
The XAML I have at the moment is:
<Image Name="imgPic1"
Width="100"
Height="75"
Stretch="Fill"
VerticalAlignment="Top" />
I thought I would be just able to put a one-unit margin or padding on the image and set a background color to 000000 but Padding and Background are both invalid for images.
What is an easy way to do this in XAML? Do I really have to put each image inside another control to get a border around it or is there some other trickery I can use?
Simply wrap the Image in a Border control
<Border BorderThickness="1">
<Image Name="imgPic1"
Width="100"
Height="75"
Stretch="Fill"
VerticalAlignment="Top" />
</Border>
You could also provide a style you apply to images that does this if you don't want to do it around every image
Final solution from answer and comments added by Pax:
<Border BorderThickness="1"
BorderBrush="#FF000000"
VerticalAlignment="Top">
<Image Name="imgPic1"
Width="100"
Height="75"
Stretch="Fill"
VerticalAlignment="Top"/>
</Border>
The accepted answer will not work because of the problem described here
https://wpf.2000things.com/2011/04/17/279-adding-a-border-around-an-image-control/
I solved it this way.
<Viewbox>
<Border BorderThickness="3" BorderBrush="Red">
<Image Stretch="None" ></Image>
</Border>
</Viewbox>
I just stumbled upon this post and the other answer did not work right. Maybe because I now use framework 4 and this post is old?
In any case - if someone will see this by chance in the future - here is my answer:
<Border Name="brdSiteLogo"
BorderThickness="2"
BorderBrush="#FF000000"
VerticalAlignment="Top"
HorizontalAlignment="Left"
Margin="12,112,0,0"
Height="128"
Width="128">
<Image Name="imgSiteLogo"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Stretch="Fill"/>
</Border>
The border thickness and brush are important (if you wont choose a color - you will not see the border!!!)
Also, the border should be aligned on your window. The image is "inside" the border, so you can use margins or just stretch it like I did.
Please pardon my ignorance- I'm very new to WPF.
I am looking to implement a minor, visual effect in my application that gives the look of "inner" rounded corners. The window in question has a dark border that encapsulates several UIElements, one of which is a StatusBar, located at the bottom of the window. This StatusBar has a dark background that matches the window's border. Above the StatusBar is a content view, which is currently a Grid- its background is semi-transparent (I think that this is something of a constraint- you can see through the content view to the desktop below). I would like for the content view (represented by the transparent, inner area in the figure below) to have the look of rounded corners, though I expect to have to sort of create the illusion myself.
(Can't post the image because I'm a lurker and not a poster- please find the drawing here)
My first approach was to add a Rectangle (filled with the same, dark color as the border) immediately above the StatusBar and to assign a Border with rounded corners to its OpacityMask (similar to the solution proposed by Chris Cavanagh**). Sadly, the effect that is produced is the exact opposite of that which I am trying to achieve.
I understand that the Clip property can be of use in this sort of situation, but it seems to me that using any sort of Geometry will prove to be inadequate as it won't be dynamically sized to the region in which it resides.
EDIT: Including my XAML:
<Grid Background="{StaticResource ClientBg}" Tag="{Binding OverlayVisible}" Style="{StaticResource mainGridStyle}">
<DockPanel LastChildFill="True">
<!-- Translates to a StackPanel with a Menu and a Button -->
<local:FileMenuView DockPanel.Dock="Top" />
<!-- Translates to a StatusBar -->
<local:StatusView DockPanel.Dock="Bottom" />
<!-- Translates to a Grid -->
<local:ContentView />
</DockPanel>
</Grid>
Any pointers are more than welcome- I'm ready to provide more indepth detail if necessary.

EDIT: Now I got what you mean. In fact you can use Path + OpacityMask approach. You have to draw "inverted" path, to use it as opacity mask. But I have simpler and faster solution for you :). Use Border + CornerRadius, and fill the gaps with solid paths. Just try the following code in Kaxaml and let me know if this is what you were looking for:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="240"
Height="320"
AllowsTransparency="True"
Background="Transparent"
WindowStyle="None">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="24"/>
<RowDefinition Height="*"/>
<RowDefinition Height="24"/>
</Grid.RowDefinitions>
<Border Background="Black"/>
<Border Grid.Row="1" BorderBrush="Black" BorderThickness="5">
<Grid>
<Border Background="White" CornerRadius="0, 0, 5, 5" Opacity="0.7"/>
<Path
Width="15"
Height="15"
HorizontalAlignment="Left"
VerticalAlignment="Bottom"
Data="M10,10 L5,10 L5,5 C4.999,8.343 6.656,10 10,10 z"
Fill="Black"
Stretch="Fill"/>
<Path
Width="15"
Height="15"
HorizontalAlignment="Right"
VerticalAlignment="Bottom"
Data="M10,10 L5,10 L5,5 C4.999,8.343 6.656,10 10,10 z"
Fill="Black"
Stretch="Fill">
<Path.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleX="-1"/>
<TranslateTransform X="15"/>
</TransformGroup>
</Path.RenderTransform>
</Path>
</Grid>
</Border>
<Border Grid.Row="2" Background="Black"/>
</Grid>
</Window>
PS: You can simplify this solution by avoiding render transforms, but you got the idea.
In my project I want to display a small logo on the side of a custom control. Since I have no canvas I thought maybe a Visual Brush would be a good Idea to place the logo in the background.
<VisualBrush>
<VisualBrush.Visual>
<Rectangle Width="200" Height="200" Fill="Red" />
</VisualBrush.Visual>
</VisualBrush>
But the Rectangle I am using right now is not 200x200. It takes the complete available space. Thats not what I want. I also tried a Viewbox and set the stretch property but the result is the same because in the end I don't need a simple Rectangle but a canvas with many path objects as children. A Viewbox supports only one child.
This there any way to get around this problem?
You need to set TileMode, Stretch, AlignmentX and AlignmentY properties on your VisualBrush:
<VisualBrush TileMode="None" Stretch="None" AlignmentX="Left" AlignmentY="Top">
<VisualBrush.Visual>
<Rectangle Height="200" Width="200" Fill="Red"></Rectangle>
</VisualBrush.Visual>
</VisualBrush>
Add Grid and this Set Vertical alligment to Top and Horizontal alignment to Right
Sample code
<VisualBrush x:Key="myVisual">
<VisualBrush.Visual>
<Grid>
<Rectangle Height="200" Width="200" Fill="Red" HorizontalAlignment="Right" VerticalAlignment="Top" ></Rectangle>
</Grid>
</VisualBrush.Visual>
</VisualBrush>
For me, I set the following attribute on the VisualBrush, and the VisualBrush now looks exactly like a MediaElement:
Stretch="Uniform"
I have set a canvas' background to an image of a company logo. I would like for this image to be aligned to the bottom right corner of the canvas.
Is it possible to do this, or would it require for the image to be added into the canvas as a child? That would not work with this program as all children of the canvas are handled differently.
Thank You
Will this work? (It worked for me, anyway.)
<Canvas>
<Canvas.Background>
<ImageBrush ImageSource="someimage.jpg" AlignmentX="Right"
AlignmentY="Bottom" Stretch="None" />
</Canvas.Background>
</Canvas>
AFAIK The WPF Canvas needs child UI elements to be positioned using absolute co-ordinates.
To achieve the right-bottom-anchored effect, I think you'd need to handle the window resize event, recalculate and apply the Top,Left co-ordinates for the child Image element to always stick to the right buttom corner.
<Window x:Class="HelloWPF.Window1" xmlns...
Title="Window1" Height="300" Width="339">
<Canvas>
<Image Canvas.Left="195" Canvas.Top="175" Height="87" Name="image1" Stretch="Fill" Width="122" Source="dilbert2666700071126ni1.gif"/>
</Canvas>
</Window>
How about containing the canvas and image inside of a Grid control like so?
<Window ...>
<Grid>
<Canvas/>
<Image HorizontalAlignment="Right" VerticalAlignment="Bottom" .../>
<Grid>
</Window>
This is my solution using a border inside the canvas to align the image. This solution works well when canvas is resized:
<Canvas x:Name="MiCanvas" Height="250" Width="500" Background="Aqua">
<Border x:Name="MiBorderImage"
Width="{Binding ElementName=MiCanvas, Path=ActualWidth}"
Height="{Binding ElementName=MiCanvas, Path=ActualHeight}"
Background="Transparent">
<Image x:Name="MiImage" Source="/GraphicsLibrary/Logos/MiLogo.png"
HorizontalAlignment="Right"
VerticalAlignment="Bottom"
Stretch="None" />
</Border>
</Canvas>
