Coordinates in WPF Canvas - c#

when defining coordinates for canvas shapes in XAML files, is it possible to do something like this:
<Canvas x:Name="myCanvas"
DockPanel.Dock="Bottom"
VerticalAlignment="Stretch">
<Canvas.Background>
<SolidColorBrush Color="White" Opacity="100" />
</Canvas.Background>
<Ellipse x:Name="ell1"
Width="30"
Height="30"
Stroke="Black"
StrokeThickness="1"
Fill="Red"
Canvas.Left="100"
Canvas.Top="50" />
<Ellipse x:Name="ell2"
Width="30"
Height="30"
Stroke="Black"
StrokeThickness="1"
Fill="Red"
Canvas.Right="100"
Canvas.Top="50" />
<Line Stroke="Black"
StrokeThickness="1"
X1="ell1.Canvas.Right" *** look here ***
Y1="ell1.Canvas.Top + ell1.Height/2" *** look here ***
X2="ell2.Canvas.Left" *** look here ***
Y2="ell2.Canvas.Top + ell2.Height/2" /> *** look here ***
</Canvas>
Or the only way of doing it is through C#?
Thanks,

You can indeed bind to an attached property like this:
<Line ... X2="{Binding Path=(Canvas.Left), ElementName=ell1}" />
But there is no + or / operators defined in XAML so you will have to write some code to be able to set the Y1 property to 50 + 30 / 2.
After all XAML is a markup language and C# is a programming language.

This should generate the desired result without too much hassle. You may have to adjust the Margin of the Grid.
<Grid DockPanel.Dock="Bottom" Margin="100,50">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Ellipse Grid.Column="0" Width="30" Height="30"
Stroke="Black" StrokeThickness="1" Fill="Red"/>
<Ellipse Grid.Column="2" Width="30" Height="30"
Stroke="Black" StrokeThickness="1" Fill="Red"/>
<Rectangle Grid.Column="1" Fill="Black" Height="1"/>
</Grid>
This is even simpler:
<DockPanel DockPanel.Dock="Bottom" Margin="100,50">
<Ellipse DockPanel.Dock="Left" Width="30" Height="30"
Stroke="Black" StrokeThickness="1" Fill="Red"/>
<Ellipse DockPanel.Dock="Right" Grid.Column="2" Width="30" Height="30"
Stroke="Black" StrokeThickness="1" Fill="Red"/>
<Rectangle Fill="Black" Height="1"/>
</DockPanel>

I have a problem with WPF Application. It runs perfectly on Windows 10, tested on latest update 1803 and latest Insider Fast, but when application is run on Windows 8 or 7, application starts, uses 1 GB of unamanged RAM for few milliseconds and then renders only white screen. App is running and I can see cursor changing and code running in background, but when I try to move Window for example, application crashes with Out Of Memory exception and Application does not have enough memory to execute.
I do not understand this problem, I tried removing code from it... It can be libraries or XAML.
I tried different .NET versions. I am out of ideas.
Did anyone ever had this problem? How to solve it? I can publish code if required to get help... I am really lost.

You must have set these two properties to your Window:
window.AllowsTransparency = true;
window.WindowStyle = WindowStyle.None;
This two properties will change your window into a layered window and will take much more memory than a normal one.
If you have done so, remove it. If you want a custom title bar, try to use a WindowChrome.

I'm trying to make a custom viewfinder for ZXing.Mobile. It should be similar to viewfinder for dm77 (Android library). In original it looks like the picture below:
Original ViewFinder picture
I have next XAML definition for the view:
<Grid Name="Overlay" Visibility="Visible">
<Grid Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="2*" />
<RowDefinition Height="2*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.1*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="0.1*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Row="1" Grid.Column="1" >
<Rectangle Stroke="Green" StrokeThickness="4" StrokeDashArray="2" />
</Grid>
</Grid>
</Grid>
How can I make the border of view looks exactly like it does on the picture?

Try these lines of code. Change the values as you want.
<Grid Width="500" Height="500">
<Line Stroke="Yellow" StrokeThickness="5" X2="100" HorizontalAlignment="Left" VerticalAlignment="Top"/>
<Line Stroke="Yellow" StrokeThickness="5" Y2="100" HorizontalAlignment="Left" VerticalAlignment="Top"/>
<Line Stroke="Yellow" StrokeThickness="5" X2="100" HorizontalAlignment="Right" VerticalAlignment="Top"/>
<Line Stroke="Yellow" StrokeThickness="5" Y2="100" HorizontalAlignment="Right" VerticalAlignment="Top"/>

I am trying to learn XAML and am creating a simple app based off this:
I have created the buttons for each of the circles, but where I am running into an issue is the drawing of the lines and autosizing them to the button positions. I was wondering if there is a way to bind the start/end point of a path to a button location? Is there a better way doing this in XAML?
Here is what my current XAML code is...

If you stick to handle it in XAML using grids you can use a canvas for each button-line-button constellation.
I'd recommend to handle it in code.
See my example bellow.
I bound actual Canvas properties to each button and the connector line.
It should properly if you resize the container grid, or reposition your canvas.
RESULT:
CODE:
<Grid Width="300" Height="300">
<Canvas x:Name="lineCanvas1">
<Line x:Name="line" Fill="Green" Stroke="Green" UseLayoutRounding="False" X1="1" Y1="1" X2="{Binding ActualWidth, ElementName=lineCanvas1}" Y2="{Binding ActualHeight, ElementName=lineCanvas1}" />
<Button x:Name="button1" Content="Button One" HorizontalAlignment="Stretch" Margin="0" VerticalAlignment="Stretch" Background="Red" RenderTransformOrigin="1,1" Height="100" Width="100"/>
<Button x:Name="button2" Content="Button Two" HorizontalAlignment="Stretch" Margin="-100,-100,0,0" VerticalAlignment="Stretch" Background="Red" Canvas.Left="{Binding ActualWidth, ElementName=lineCanvas1}" Canvas.Top="{Binding ActualHeight, ElementName=lineCanvas1}" RenderTransformOrigin="1,1" Height="100" Padding="0" Width="100"/>
</Canvas>
</Grid>

I hope someone can help, I am fairly new to WPF and want to create a button that looks like the menu button in mobile Apps and on responsive web applications, that is a square button with three horizontal lines.
I have tried creating a button with a canvas and three lines but this does not work correctly.
Can anyone suggest the XAML that could achieve this please?
EDIT
I have added the code in to my application from the answer, the XAML is below
<Button x:Name="systemButton" IsTabStop="False" Style="{StaticResource LightWindowButtonStyle}" HorizontalAlignment="Left" VerticalAlignment="Top">
<Button.Content>
<Grid Width="31" Height="23" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Path Data="M8,8 L28,8" Fill="{TemplateBinding Foreground}" Height="4" StrokeThickness="4" Stretch="Fill" Stroke="{TemplateBinding Foreground}" VerticalAlignment="Center" />
<Path Data="M8,8 L28,8" Fill="{TemplateBinding Foreground}" Height="4" StrokeThickness="4" Stretch="Fill" Stroke="{TemplateBinding Foreground}" VerticalAlignment="Center" Grid.Row="1" />
<Path Data="M8,8 L28,8" Fill="{TemplateBinding Foreground}" Height="4" StrokeThickness="4" Stretch="Fill" Stroke="{TemplateBinding Foreground}" VerticalAlignment="Center" Grid.Row="2" />
</Grid>
</Button.Content>
</Button>
In my AeroWindow class I am getting the instance of the button and binding to the click event as below
var systemButton = this.GetTemplateChild("systemButton") as Button;
if (systemButton != null)
{
systemButton.Click += this.SystemButtonOnClick;
}
But the event handler never gets fired when I click the button. I have checked and systemButton is not null therefore the Click event gets bound to the event handler, the breakpoint on the event handler never gets hit through. Anyone have any ideas?

You need to put your content in the Button, and for that you apply a content template.

I have updated my answer. In DataTemplate we are using Height, and in next Button we are using only StrokeThickness.
And for using style you can do following changes :
<Window.Resources>
<DataTemplate x:Key="DataTemplate1">
<Grid Width="51" Height="42">
<Grid.Resources>
<SolidColorBrush x:Key="PathFillBrush" Color="#FF2DBE29"/>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Path Data="M0,5 L51,5" Fill="{DynamicResource PathFillBrush}" Height="3" Stretch="Fill" Stroke="#FF2DC65A" VerticalAlignment="Center"/>
<Path Data="M0,5 L51,5" Fill="{DynamicResource PathFillBrush}" Height="3" Stretch="Fill" Stroke="#FF2DC65A" VerticalAlignment="Center" Grid.Row="1"/>
<Path Data="M0,5 L51,5" Fill="{DynamicResource PathFillBrush}" Height="3" Stretch="Fill" Stroke="#FF2DC65A" VerticalAlignment="Center" Grid.Row="2"/>
<Path Data="M0,5 L51,5" Fill="{DynamicResource PathFillBrush}" Height="3" Stretch="Fill" Stroke="#FF2DC65A" VerticalAlignment="Center" Grid.Row="3"/>
<Path Data="M0,5 L51,5" Fill="{DynamicResource PathFillBrush}" Height="3" Stretch="Fill" Stroke="#FF2DC65A" VerticalAlignment="Center" Grid.Row="4"/>
</Grid>
</DataTemplate>
<Style TargetType="Button">
<Setter Property="ContentTemplate" Value="{DynamicResource DataTemplate1}"/>
</Style>
</Window.Resources>

If you test the code below and any bright image you will see 4 columns and 4 rows painted over the used image. I need this configuration to use for some kind of effect.
Basically I made it and it works but these grid lines I would like to remove and do not know how. Is it maybe related to the implementation of the Grid control itself ?
Grid's property ShowGridlines is false.
There is a possibility to use the Canvas instead of the grid and do the placement manually but I would like to stay with the Grid and use the Canvas as the last solution.

You may set the RenderOptions.EdgeMode property to Aliased on the Grid to avoid this effect:
<VisualBrush x:Name="DissolveInBrush" TileMode="None" >
<VisualBrush.Visual>
<Grid RenderOptions.EdgeMode="Aliased">
...
</Grid>
</VisualBrush.Visual>
</VisualBrush>
