Images are not displayed at run-time in ListBox [duplicate]

All, I have the following start to a small application that checks .resx files for consistency of embedded brackets (so that runtime errors of non-matching "... {0}" strings don't happen). I have the following XAML for the MainWindow.xaml, and my particular problem relates to the image that is to be displayed on the button
<Window x:Class="ResxChecker.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

</Button>
</Grid>
</Window>
The image has 'Build Action = Resource', 'Copy to output directory = Do not copy' - the image shows in the designer but not at runtime. I have seen the following questions and read the relevant answers, but none resolve the problem:
WPF control images not displayed when consumed by an application
image problem in wpf (image does not show up)
Background Image of Button not showing in WPF
How do I get the button image to appear at runtime?

Change the build action to 'Resource'.
Also your pack url is wrong. Either use:
Source="pack://application:,,,/Resource/UserCost2013Open16.png"
or simply
Source="/Resource/UserCost2013Open16.png"

There are 2 Solutions:
1: Change the settings of the image:
Build Action = Content
Copy to output directory = Copy if newer
Source="pack://siteoforigin:,,,/Resources/UserCost2013Open16.png"
2: When Using application instead of siteoforigin in the source path, you have to possible ways:
a) Image will be in a SubFolder called "Resources" and .exe file will be small
Source="pack://application:,,,/Resources/UserCost2013Open16.png"
Build Action = Content
Copy to output directory = Copy if newer
b) Image will be included in the .exe and no Subfolder with imagefile will exist
Source="pack://application:,,,/Resources/UserCost2013Open16.png"
Build Action = Resource
Copy to output directory = Copy if newer

Assuming that you have set your Build Action to Resource.
Use the URI-PACK-FORMAT:
pack://application:,,,/ResourceFile.xaml or pack://application:,,,/Subfolder/ResourceFile.xaml or
pack://application:,,,/ReferencedAssembly;component/ResourceFile.xaml
Those are the most common examples.
Also, in my case it was still not showing.
Clean & Rebuild NOT just Build fixed it for me (VS 2019)!

In my case I had the images in a separate project named Common and the images were under a folder named Resources in this project. In my other project, I added a reference to Common and set the source of the images like this:
<Image Source="/Common;component/Resources/anImage.png"/>
The images have the Build Action set to Resource and Copy to Output Directory to Do not copy. However, for some strange reason it wasn't working until I deleted every assembly file in my solution and made a Clean Solution and Build Solution. Not sure why, but it all started working at runtime once I rebuilt everything. I still can't figure out why it was working at Design Time though.

Go to your image in the resources folder, right click on the image, go to properties, click on the Build Action property, and change it from None to Resource. That'll work.

You should add any thing inside Solution Explorer of Visual Studio.
Instead of just copying the image to folder in Windows Explorer, press Right Click on any folder in Solution Explorer go to Add > Existing Item... and select the path to your resource to be added.

I defined my image as next:
<Image Source="/Resources/Images/icon.png"/>
The image is displayed in Visual Studio designer but no image is displayed when I launched the app! It made me nuts!
I tried all Build Actions with clean/build, no luck.
In my case the problem is caused by the fact that the control (which uses Image) and the app itself are in different projects. Resources/Images folder is in the Controls project. As result the app attempted to find icon.png in its own Debug folder, but actually it is in Controls' Debug folder.
So two solutions work for me:
1) put Resources/Images in the app's project (not so good when there are several projects which use controls from Controls project, but it works)
2) specify the name of Controls project explicitly inside Image:
<Image Source="/Controls;component/Resources/Images/icon.png"/>

Visual Studio 2022 (but should work in other versions). Add your image to a folder named as you want, in this example I created an Assets named folder. Then set the image's property to Resource in the Build Action. Then select the image in the folder and drag and then drop the into <MenuItem.Icon> and it should path properly..
Note you may need to Rebuild the project, the compiler sometimes doesn't recognize new resources as a need to rebuild.

Make a new folder and put your pictures in the new folder and write this in XAML
<Image Source="/newfolder/icon.png"/>

For me, changing the "build action" to "Resource" and the "copy to output directory" to "Do not copy" has solved my problem.

Source="file:///D:/100x100.jpg"/> works for me.

WPF Image won't show in Class Library Project

I can't display an image on WPF window during runtime. However, it is shown during design mode. The image is located in Images folder and Build action is set to Content as well is Copy to output to Copy Always. The output Any suggestions?
===EDIT====
The output type of a project is : Class Libray, if I change it to Window Application the bellow are workign fine. However I still need to build it is Class library.
2nd try
<Image Source="pack://siteoforigin:,,,/Images/Logo2.png" Grid.Row="0"/>
3rd try
<Image Source="pack://application:,,,/Images/Logo2.png" Grid.Row="0"/>
Also,
If I put a full path to the image location it is working, apparently this is not ideal situation:
<Image Source="C:/.../Images/Logo2.png" Grid.Row="0"/>

Rebuild your entire solution and try again. It probably didn't do a build with images in it when you tried it again.
Also use your 3rd try again then build action to content, no need to make a copy always.

After several trials the answer was quite simple:
For Class Library Project set your images Build Action to Resource and get a reference in Xaml as:
<Image Source="/YOURNAMESPACE;component/Images/Logo.png"/>

It won't work with png, but convert to jpg and write:
<Image Source="/YOURNAMESPACE;component/Images/Logo.jpg"/>
That works for me :)

Images not showing in a Windows Store Application

I am building a Windows Store (WinRT) application, and I have added in buttons to manipulate items in a list, I am using images for these buttons. I have followed numerous sets of information but can't get these images to show up, I have tried the following:
<Button>
<Image Source="/Images/add.png"/>
</Button>
<Button>
<Image Source="mx-app://Images/add.png"/>
</Button>
I have tried the above with the image set to copy local, and then with different build actions, the image just never shows when I run the application.

If you're including the images in the application package, they should be marked as Content (which they would by default when pulling adding them to the project).
Your first invocation should work, assuming you have a top level folder in your project called Images.
Your second invocation should be (it's just a more explicit version of the first):
<Button>
<Image Source="ms-appx:///Images/add.png"/>
</Button>

Try setting the build action on each image to Resource.
Then you should be able to write
<Button>
<Image Source="/Images/add.png"/>
</Button>

Right click on the image. Properties -> Build Action. Ensure That "Build Action" is Content

Why do my images show at designtime and not at runtime?

I have a WPF <Image> that I am trying to display on a <Button> inside of a <Toolbar> with the following code.
<ToolBarTray>
<ToolBar Height="26" Name="toolBar1" VerticalAlignment="Top" >
<Button Name="StampButton" Click="StampButton_Click">
<Image Source="/MyApp.Resources;component/Resources/MyImage.png"
Height="16" Width="16" Stretch="Fill"/>
</Button>
</ToolBar>
</ToolBarTray>
The image shows up just fine at design time. However, at runtime nothing is displayed. The resources are in another dll called MyApp.Resources. The button is actually created just fine and the click event works fine also.

Set your image build action to "Resource". Try to use full source path.

I was getting same problem - image displaying at design time, but not at runtime.
I had build action set to resource, tried different pack uris etc etc, but solution was simple
<Window.Resources>
<BitmapImage x:Key="your_image_key" UriSource="your_image.png" />
<Image Source="{StaticResource your_image_key}"/>
</Window.Resources>

This is what worked for me, from a site called wpf-tutorial.com:
<Image Source="/WpfTutorialSamples;component/Images/copy.png" />
Images is a subfolder of the project folder in my case, and I assume also in this sample.

'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.'

The exception in the title is thrown when I open a window in WPF, the strange thing is that this does not happen on my Windows 7 development machine nor does it happen when it is deployed on Windows 7.
I only get this error on Windows XP, and only the second time that I open the window.
Here is the code to open the window:
ReportParametersWindow win = null;
bool canOverWrite = _shownReports.Contains(rpt.FriendlyName);
if (!(canOverWrite))
win = new ReportParametersWindow(rpt.FriendlyName, rpt.ReportParameters, canOverWrite);
else
win = new ReportParametersWindow(rpt.FriendlyName, (container.ParametersWindow as ReportParametersWindow).Controls, canOverWrite);
win.ShowDialog();
And the XAML for the window:
<Window xmlns:my="clr-namespace:MHA.Modules.Core.Controls;assembly=MHA.Modules.Core"
x:Class="MHA.Modules.Reports.Views.ReportParametersWindow"

</ScrollViewer>
<Grid Grid.Row="1">

<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<CheckBox ToolTip="This will replace the first report of the same type that was shown." Name="chkOverwrite" Content="Overwrite old" VerticalAlignment="Center" Margin="5,0"></CheckBox>
<Button Grid.Column="2" HorizontalAlignment="Right" Margin="5,0" Height="30" Style="{StaticResource DionysusButton}" Width="100" IsDefault="True" Click="Button_Click">
<StackPanel Orientation="Horizontal">
<Image Source="/MHA.Modules.Reports;component/Images/Success.png"></Image>
<TextBlock Margin="5,0" Text="Accept" VerticalAlignment="Center"></TextBlock>
</StackPanel>
</Button>
</Grid>
</Grid>
Does anyone have suggestions?

The solution is quite a weird one but I have it figured out.
I realized that the error was occurring on the InitializeComponent() of the window, I then added a try catch to the constructor and showed the InnerException of the Exception.
The error that I received is "Image format not recognized".
I have no idea why this happens only on XP and the second time that the window is shown but by replacing my .ico with a .png the problem was resolved.
Hope this helps someone.

I just ran into this issue as well... I know this is old, but what I had to end up doing was set the images to Resource, and Copy Always... only by browsing my /bin/Debug folder did I realize that the images were not at a valid path location

This problem can also occur if the required image is not available at the specified location. So Check the inner exception and add any image that might have been missed or misspelled.

I got this error because my Command Binding of a Button was wrong:
<Button Command="MyCommand" />
instead of
<Button Command="{Binding MyCommand}" />

You Should first Import Image to your project
Solution Explorer - Show All
then Right Click on the image and select Include
Now Use
end

In my case the root cause was wrong BuildAction property on all images. I fixed it by changing BuildAction from Content to Resource.

I got this exception after moving my Resource Dictionary from root of my application to a subdirectory. In my case the problem were Image paths inside my Style setters inside the dictionary. After I preceded them with a forward slash '/', the application started to work again. If you're having a similar problem, open the resource dictionary, and the error will be highlighted with the blue 'squiggly' line.

In my case, I have added 'WpfToolkit' refrence to my module, and there is no need.
After deleting this reference, everything was ok. Strange!

Just go to Project>[Your Project Name] Settings and set your .ico file as icon now your .ico file is mentioned in your manifest file and you can simply include your .ico file in your XAML file using
Icon="[icon file name].ico"
<Window x:Class="[Your project's name].MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="" Height="500" Width="720"
Icon="[your icon's name].ico">

In my case, I found the mew added icon(image) file is not added into my project. It is resolved after I added these new image files into my project, not just file copy.

In my case the files existed on disk but were not referenced in the project. I added them to the project but the error persisted despite reloading the solution and restarting Visual Studio.
I changed the references to an existing file that was already in the project and it ran fine (albeit with the wrong graphic). I then changed it back to the original reference and it ran fine again but with the correct image. Presumably the error was getting cached somehow until it was flushed out of the system...

Remove the "WPFToolkit" reference from your cs.proj file.
<Reference Include="WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
It should do the trick.

copy and paste the file name is changed. that's why I get this error.

well, in my case I added the new photos to the image Folder in FileExplore while image folder was added to the project while ago. and there wasn't any problem with the image path in the project. but when I build the project I face to the same error.
then I add those new photos to project by right click on the image folder and add the existing item and selected new photos. then I cleaned the solution and build it again.

There are many ways to cause this issue. Since the exception isn't specific. Here is a list of solutions to try from this thread.
Firstly, you can try/catch the InitializeComponent() call which is throwing the exception to get more details about what happened.
If the image is an icon (.ico) file use an image (.png) or equivalent instead
In some cases .ico files are problematic - I was using .NETCore
Make sure your image file has a build action of Resource or Embedded Resource
The resource files described in this section are different than the
resource files described in XAML Resources and different than the embedded
or linked resources described in Manage Application Resources (.NET). - MSDN
Ensure your reference to the file is spelled and pathed correctly
Example: "/Resources/logo.png" if you have a folder at the project level
Notice the prefix /.
Colors codes in the xaml file missing the hashtag prefix "#000FE0"

In my case, another program was using the image and somehow was blocking the access.
I mad a copy and this worked.
<Window
.....
Height="450" Width="400"
Icon="../Resources/SettingsCopy.png" >

To improve upon user2125523:
If you've added the image to the project and checked and double checked that the file spelling is correct, try renaming the image to mirror a different existing image. Build/run, then put your image file name back and build/run again.
For example:
My original code kept throwing the OP error on LargeImage="/img/32/delete.order.png" even though this file exists.
<telerik:RadRibbonButton Text="Object Properties" Size="Large"
Name="PropertiesButton" IsTabStop="True"
telerik:ScreenTip.Description="Get object properties"
Click="PropertiesButton_Click"
LargeImage="/img/32/properties.png"
SmallImage="/img/16/properties.png" />
<telerik:RadRibbonButton Text="Reset Tab Order" Size="Large"
Name="ClearTabOrderButton" IsTabStop="True"
telerik:ScreenTip.Description="Reset tab order of all fields"
Click="ClearTabOrder_Click"
LargeImage="/img/32/delete.order.png"
SmallImage="/img/16/delete.order.png" />
So, I changed LargeImage="/img/32/delete.order.png" to LargeImage="/img/32/properties.png", ran the program, and changed it back to "/img/32/delete.order.png". Finally the error was gone.
FYI VS2012.3 Win8.1Preview

I had the same issue and to add an image to you solution you have to do it through the wizzard. In the solution explorer -> right click on the appropriate folder-> add existing Item -> and then browse to your image. That worked for me. Hope this helps.
Thanks for you answers.

Try to set Build Action of Property of Image file as Resource.

Exception used to occur within constructor. Button's command binding was incorrect.
Eg: <Button Command="MyCommand" />--> Wrong
<Button Command="{Binding MyCommand}" />--> Right

In my case, I got this error when I had
<Border Background="eeeeee">
instead of
<Border Background="#eeeeee">
(notice the missign #)

I found "UpdateSourceTrigger=Pr" somewhere in my XAML.
Must have happened during editing.
Compiling went OK, no error then whatsoever.
Setting a BreakPoint in Application_DispatcherUnhandledException in app.xaml.cs revealed the error.
Corrected to "UpdateSourceTrigger=PropertyChanged" and the world was at it should have been.
I work on Win 10 Pro, VS2017

I encountered this error and figured out that the Image Source path format has a mistake. a forward slash / was added as follows:
Source="/TestProject;component/Images//hat_and_book.png
I removed that extra slash and the error had gone.

I got the same error message, then I find this solution :
Image not displaying at runtime C# WPF
Find your folder:Go to properties of the added image, set Build Action =>as Resource and Copy To Output Directory =>as Copy if newer.

In My case I have wrote a border tag with height property then i had to remove the value leaving the property like this
<Border Background="{StaticResource MainBackgroundBrush}" BorderThickness="1" Height="">
</Border>
The Compiler gave me the same error but the IDE have no problem so after some hard search i have found it. so make sure every property is properly set. I hope this would be useful for anyone.

it is caused by Non-standard tag option in xaml to find it set
InitializeComponent();
Function in - try mode - like this
try {
InitializeComponent();
}
catch (Exception ex) {
MessageBox.Show(ex.Message.ToString());
}
now MessageBox(( show line number with incorrect setting in control .axml file.(it just show first incorrect line tag error after Corrected it then run app again and see next one)
