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 :)
Hi
I'm trying to display an image in my app but I can't display any Image besides the images that were originally in the app like: logo.png, smallogo.png etc...
but when I choose another image it seems like it has no permission can anybody tel me why?
the following works:
<Image x:Name="imag1" Source="Assets/logo.png" Width="100" Height="300" Stretch="None" HorizontalAlignment="Left"/>
and the folowing doesn't:
<Image x:Name="imag1" Source="Assets/camel.png" Width="100" Height="300" Stretch="None" HorizontalAlignment="Left"/>
needless to say that camel.png is in Assets folder
Make sure you also have "Camel.png" added to your project. If you copy it in the Assets folder and is not added to your project, it will not work. To verify this, in the solution explorer, open the Assets folder from the folder tree view, and if it's not there, right click on the folder, Add Existing Item and add your image.
hello the problem is about the properties you should have set for camel.png.so properties should be set in properties windows to Content and Copyalways..hope it help you..
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
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"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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

<ColumnDefinition/>
<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)
I have image in project added as resource, if I try to add it to my WPF project it always end up with
Error 1 The file images\background.png is not part of the project or its 'Build Action' property is not set to 'Resource'. C:\Users\Martinek\Documents\My\Learning.Dot.Net\WPF.8\WPF.8\Window1.xaml 21 47 WPF.8
I also tried to reference full path "file:///" etc. and same results even when image is added as resource
See also XAML code with results
<ImageBrush AlignmentX="Left" ImageSource="images/background.png" Stretch="Fill" />
Attaching image:
http://i.stack.imgur.com/bSjwi.png
I noticed that you have the Copy to Output Directory option set to "Do Not Copy."
Try changing it to either "Copy Always" or "Copy if newer" and see if that helps.
Update
I just wrote a quick sample app to try to figure this out. It seems to work properly, so I'll post my code here hoping that it'll help.
<Grid>
<Grid.Background>
<ImageBrush x:Name="brush" AlignmentX="Left" ImageSource="images/have_the_dumb.jpg" Stretch="Fill" />
</Grid.Background>
</Grid>
In the code-behind, I added some tracing code to see where the ImageBrush thinks its ImageSource is.
public ImageDisplay()
{
Trace.Listeners.Add(new TextWriterTraceListener(#"c:\happyface.trace.log"));
Trace.AutoFlush = true;
InitializeComponent();
Trace.WriteLine(String.Format("Image thinks it's in {0}", brush.ImageSource.ToString()));
}
When running that in Debug mode, you should see a line written to the Output window (as well as to the *.trace.log file) with the URI where it thinks the image is located.
I ran it with the image in an images folder off the root of my solution. I tried it with the image set as "Content" (with "Copy if newer") as well as "Resource" (with do not copy), and it ran successfully both times.
Hope this points you in the right direction.
Try the pack syntax:
<ImageBrush ImageSource="pack://application:,,,/Images/background.png" />
<ImageBrush AlignmentX="Left" ImageSource="pack://application:,,,/[ASSEMBLY_NAME];component/Images/background.png" Stretch="Fill" />
[ASSEMBLY_NAME] is the name of the dll or executable that contains the resource (without an extension).
I have two ideas - use a backslash instead of a forward slash. (It shouldn't matter - but that's what works here...)
The other idea is that your project path looks messed up - try copying the solution to the root of your harddrive. You might have hit some weird problem with the path containing too many periods/slashes or whatever.
