Mouse events not firing in Windows WPF

I have a simple WPF application
<Grid>
<Border BorderBrush="Black" BorderThickness="1"
HorizontalAlignment="Left" Height="388" Margin="10,10,0,0" VerticalAlignment="Top" Width="329"/>
<Image x:Name="PreviewImg" HorizontalAlignment="Left" Height="400" Margin="10,10,0,0" VerticalAlignment="Top" Width="329" MouseDown="PreviewImgMouse" AllowDrop="True" PreviewMouseWheel="PreviewImg_PreviewMouseWheel" MouseEnter="Entered" Focusable="True"></Image>
<Label Content="Matched Products" HorizontalAlignment="Left" Margin="344,10,0,0" VerticalAlignment="Top" Width="290"/>
<Label Content="Unknown Products" HorizontalAlignment="Left" Margin="661,10,0,0" VerticalAlignment="Top" Width="290"/>
<TextBlock x:Name="MatchedProducts" HorizontalAlignment="Left" Margin="349,36,0,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Height="362" Width="295"/>
<TextBlock x:Name="UnknownProducts" HorizontalAlignment="Left" Margin="666,36,0,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Height="362" Width="295"/>
<Grid HorizontalAlignment="Left" Height="50" Margin="10,410,0,0" VerticalAlignment="Top" Width="957">
<Button x:Name="FinalizeBtn" Content="Finalize" HorizontalAlignment="Left" Margin="826,10,0,0" VerticalAlignment="Top" Width="120" Height="30"/>
<Button x:Name="NewEntryBtn" Content="Create new entry" HorizontalAlignment="Left" Margin="701,10,0,0"
VerticalAlignment="Top" Width="120" Height="30"/>
<Button x:Name="FreeBtn" Content="Free Button" HorizontalAlignment="Left" Margin="576,10,0,0" VerticalAlignment="Top" Width="120" Height="30"/>
</Grid>
</Grid>
All the events defined under the Image component are not firing, I tried all of googles first page searches, but none of them work.
I read about the difference of Routed events in my application both MouseDown and PreviewMouseDown should work.
The only thing that can block the image is Border component, but I did try without it and still nothing, and since it is declared first the image should overlay it...?
All function names are correct since they were automatically generated.
I can paste in the .cs file if it can help.
Thanks
E1: Somehow it works now, but I have no idea what fixed it...
One change I did was mode the image inside the border:
<Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" Height="388" Margin="10,10,0,0" VerticalAlignment="Top" Width="329">
<Image x:Name="PreviewImg" Height="400" Margin="0" VerticalAlignment="Center" HorizontalAlignment="Center" Width="329" MouseDown="PreviewImgMouse" AllowDrop="True" PreviewMouseWheel="PreviewImg_PreviewMouseWheel" MouseEnter="Entered" Focusable="True"/>
</Border>
But I can't image that this fixed it.

You need to define a source for your image like <Image Source="image.jpg". Without the image the events will not fire.

For advanced users
Use a Button styled as an Image, see #Richard's answer with WPF Image Control with Click event
For beginners
The Image component needs a source to fire events as posted by #Örvar. Adding a transparent source is the solution, although a hacky one.

One way of achieving what you want is to place the image in a button and removing the button styles. There is an excellent example here:
WPF Image Control with Click Event

How do i set the background image of a button in a WPF Application?

I cannot find the background-Image Property in the properties panel of the button, I have the images stored for each button in the root directory of my solution as Jpegs, the project is a WPF and I don't know how to set the image in the XAML or C# code. I am developing in Visual Studio 2017 Community Edition
All problems I have seen before are for different versions of Visual Studio, so I can't find the answer
*edit - i am trying to change the background image of a button at design time in the XAML editor, not create an onclick button to change a background image. So if i have this button in XAML:
<Button x:Name="keyBtn"
Content="Keyboard/Mouse"
HorizontalAlignment="Left" VerticalAlignment="Top"
Width="400" Height="800" FontFamily="Verdana"
Background="#FFB41717"
Margin="0,-31,0,0"/>
Which Part should I refer to in the ".background" property?

It is probably easier than you think..
Try this after you add the image to your project.
<Button x:Name="keyBtn"
HorizontalAlignment="Left" VerticalAlignment="Top"
Width="400" Height="800" FontFamily="Verdana"
Background="#FFB41717"
Margin="0,-31,0,0">
<Image Source="myImage.png" />
</Button>
Note that you need to remove the content since now the image is the content.
If you wish the text as well - you can try this:
<Button x:Name="keyBtn"
HorizontalAlignment="Left" VerticalAlignment="Top"
Width="400" Height="800" FontFamily="Verdana"
Background="#FFB41717"
Margin="0,-31,0,0">
<Grid>
<Image Source="myImage.png" Stretch="Fill" />
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="Keyboard/Mouse" />
</Grid>
</Button>
And there is another option - which might be exactly what you are looking for:
<Button x:Name="keyBtn"
Content="Keyboard/Mouse"
HorizontalAlignment="Left" VerticalAlignment="Top"
Width="400" Height="800" FontFamily="Verdana"
Margin="0,-31,0,0">
<Button.Background>
<ImageBrush ImageSource="myImage.png" Stretch="Fill" />
</Button.Background>
</Button>
But in that last option - you will have to remove the Background color as it is being replaced by the image.

Setting image's build action property

I have simple problem. I want to add image to buttons and there is one case I can't manage. In designer everything works properly, but in debug mode there is no trace of a picture inside the button. I read that I have to set Build Action property of the image to "Recourses" or "Content" but I don't have these pictures in Solution Explorer, exactly I can see them when I click "Show All Files but they have strange icon not as the one image which I can normally see in Solutions Explorer and no Build Action property.
Am I supposed to add images in different way?
<Button x:Name="loadButton" HorizontalAlignment="Left" Margin="955,0,0,443" Style="{DynamicResource SimpleButton}" VerticalAlignment="Bottom" Width="29" Height="27" FontFamily="Courier New" FontWeight="Bold" Click="loadButton_Click" Background="{x:Null}" BorderBrush="{x:Null}">
<StackPanel Orientation="Horizontal">
<Image x:Name="Load" Source="open-map.png"/>
</StackPanel>
</Button>
<CheckBox x:Name="mode" Content="Tryb tworzenia" HorizontalAlignment="Left" Margin="30,292,0,0" VerticalAlignment="Top" FontSize="18.667" Foreground="#FFAC3333" FontFamily="Courier New" IsChecked="True"/>
<Button x:Name="button1_Copy" HorizontalAlignment="Left" Margin="912,0,0,443" Style="{DynamicResource SimpleButton}" VerticalAlignment="Bottom" Width="29" Height="27" FontFamily="Courier New" FontWeight="Bold" Click="button1_Copy_Click" Background="{x:Null}" BorderBrush="{x:Null}">
<StackPanel Orientation="Horizontal">
<Image x:Name="Save" Source="save-icon.png"/>
</StackPanel>
</Button>
Thank in advanced

The files like open-map.png are not part of the C# project so you can't set any properties. Right click on the C# project and add the file to the project, then you'll be able to set its properties.

Sorry i want to add a Image Button also i tried....
i want it like this

This may help you.
<Grid Grid.Row="1" Background="White">
<StackPanel Margin="10,114,10,311">
<TextBlock Text="Enter Name"
TextWrapping="Wrap"
Tap="TextBlock_Tap"
Foreground="Black" />
<TextBox x:Name="Enter Name Field"
GotFocus="TextBox_GotFocus" BorderBrush="Gray" BorderThickness="2"
LostFocus="TextBox_LostFocus"
Foreground="RosyBrown" Height="46" Margin="27,0,56,0" />
<TextBlock Text="Enter A Model number"
TextWrapping="Wrap"
Tap="TextBlock_Tap"
Foreground="Black"/>
<TextBox x:Name="Enter A Model number Field"
GotFocus="TextBox_GotFocus"
LostFocus="TextBox_LostFocus" BorderBrush="Gray" BorderThickness="2"
Foreground="RosyBrown" Height="46" Margin="27,0,56,0" />
<Image Height="40" Width="150" Source="your image path" Tap="Image_tap" />
</StackPanel>
</Grid>

add Background="Black" (or whatever color you want) in all your TextBox.
For that what you have shown use BorderBrush="Black", decrease the border thickness if you need to. Yes, you can add a image button, use a image as your button background.
<Button>
<Button.Background>
<ImageBrush Source="your_file.jpg" Stretch="Fill"/>
</Button.Background>
</Button>
Note: It is not a good idea to write x:Name value with spaces. what you write in x:Name ultimately become a variable name of type TextBox (in this case) and c# doesn't permit variable name with space, So just delete the spaces and use x:Name="Enter_A_Model number_Field" or simply x:Name="EnterAModelNumberField"

Use your textbox surrounded with border, since you are using a white background.I think below code may help you to get an idea.
<Border BorderThickness="1" Grid.Row="2" Name="brdUsrName" HorizontalAlignment="Stretch" VerticalAlignment="Center" Height="60" Background="Black">
<TextBox Name="txtUserName" Margin="-10,-10,-10,-10" />
</Border>

Image inside textblock c# windows 8

I'm trying to put an imagine inside a textblock inside a scrollviewer for my textblock. What I'm trying to accomplish is to have it as a background for my textblock and this is not even running. It compiles but it crashes.
<Image Source="Assets\picture.png" Margin="564,196,659,292" Grid.Row="1"/>
<ScrollViewer Height="645" VerticalScrollBarVisibility="Auto" HorizontalAlignment="Left" Margin="330,113,0,0" Name="scrollViewer1" VerticalAlignment="Top" Width="627" Grid.RowSpan="2">
<TextBlock x:Name="tbl" VerticalAlignment="Top" Width="627" TextWrapping="Wrap" Foreground="White" FontFamily="Times New Roman" FontSize="22" >
</TextBlock>
I get to see the image on the designer but it crashes... Thanks!

Try this :
Using Grid or canvas we can place elements one over the other
<ScrollViewer x:Name="ScrollViewer">
<Grid>
<Image Source="Assets\picture.png" />
<TextBlock x:Name="TextBlock" />
</Grid>
</ScrollViewer>
