This is my xaml code. This parses an exception. I cannot find what is wrong there. Can someone point it to me?. This is a windows phone application,
XAML

</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>
</phone:PhoneApplicationPage>
The error that I get is shown below:
XamlParseException occurred : A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in System.Windows.ni.dll
It occurs on this line:
<shell:ApplicationBarIconButton x:Name="Reco1" IconUri="appbar.micph.rest.png"
Text="mic" Click="Reco1_Click" />
Finally I got it.
I did this first:
Debug->Exceptions
Press Add and type in,
"System.Windows.Markup.XamlParseException"
and select Common Language Runtime Exceptions,
then it gave me the exact place of where this happens.
Then I removed
Click="Reco1_Click"
So now it works fine.
What we can tell you about your problem will be severely limited from the information that you have provided. The first thing to note is that that error is a very generic error and is raised for a great many different reasons... it generally has nothing to do with the XAML, but instead points to an error in a control defined in XAML.
You say that your error occurs on this line:
<shell:ApplicationBarIconButton x:Name="Reco1" IconUri="appbar.micph.rest.png"
Text="mic" Click="Reco1_Click" />
This gives you a few possibilities:
You could have a problem with your ApplicationBarIconButton control.
You could have a problem with your IconUri property value (although you should get a compilation error if this was the case)
You could have a problem with the code in your Reco1_Click handler
In my opinion, it is most likely that you have some code in (or started from) the constructor of your ApplicationBarIconButton control that is invalid. These types of problems can be difficult to eradicate, but if you just experiment by commenting out different (relevant) parts of the code and trying to run the application again each time, then you should eventually find the problem.

I'm writing some Coded UI tests for a simple application and cannot seem to get the code to find Rectangle objects. In the specific case I have the color of the rectangle presents whether two strings match or not based on the fill color.
When trying to find the rectangle using the Coded UI Test Builder the parent object is being found instead of the rectangle. I am also seeing that the code returns that it is unable to find the rectangle when I have it search manually.
Below is the XAML for the page I am trying to test against:
<Page
x:Class="TestApp.ButtonTester"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!-- Title Panel -->
<StackPanel Grid.Row="0" Margin="19,0,0,0">
<TextBlock Text="{StaticResource AppName}" Style="{ThemeResource TitleTextBlockStyle}" Margin="0,12,0,0"/>
<TextBlock Name="pageTitle" Text="Button Tester" Margin="0,-6.5,0,26.5" Style="{ThemeResource HeaderTextBlockStyle}" CharacterSpacing="{ThemeResource PivotHeaderItemCharacterSpacing}"/>
</StackPanel>
<!--TODO: Content should be placed within the following grid-->
<Grid Grid.Row="1" x:Name="ContentRoot" Margin="19,9.5,19,0">
<StackPanel Name="buttonValidator">
<TextBlock Name="verifyText" Text="Hi" HorizontalAlignment="Center" Style="{StaticResource LargeText}"/>
<Button Name="changeText" Content="Change Text" HorizontalAlignment="Center" Click="changeText_Click"/>
<TextBox Name="guessText" Text="Enter Text From Above" TextAlignment="Center" GotFocus="guessText_GotFocus" KeyDown="guessText_KeyDown"/>
<Button Name="verifyMatch" Content="Verify" HorizontalAlignment="Center" Click="verifyMatch_Click"/>
<Rectangle Name="matchAlert" Height="50" Width="50" Fill="Black" HorizontalAlignment="Center"/>
</StackPanel>
</Grid>
</Grid>
And here is the test code I currently have:
[TestMethod]
public void TestVerifyIncorrect()
{
UITestControl verifyMatch = new UITestControl(myApp);
verifyMatch.TechnologyName = "UIA";
verifyMatch.SearchProperties.Add("ControlType", "Button");
verifyMatch.SearchProperties.Add("AutomationId", "verifyMatch");
Gesture.Tap(verifyMatch);
UITestControl matchAlert = new UITestControl(myApp);
matchAlert.TechnologyName = "UIA";
matchAlert.SearchProperties.Add("ControlType", "Rectangle");
matchAlert.SearchProperties.Add("AutomationId", "matchAlert");
var fillColor = matchAlert.GetProperty("Fill");
}
I am also seeing the Test Builder unable to detect a rectangle even when it is being used as a control.
I also looked into the Rectangle class vs the Button class and it appears the first common link in their inheritance chains is with Windows.UI.Xaml.FrameworkElement. I'm unaware of what type of ojects the Coded UI is able to detect to know if that may be the cause of the issue.
Hi I am currently building a flash card productivity app which has has a user control that i have made. On making the control i realized that it was too small for to be displayed well or rendered well on my phones display. So i then began to enlarge the user control by increasing the width and height of the control and also increasing the size of the text of all the controls contained in the user control .Only when i one try to run the control i get given this exception :
An exception of type 'Windows.UI.Xaml.Markup.XamlParseException' occurred in SuperCards.exe but was not handled in user code
WinRT information: Failed to create a '%1' from the text '%0'. [Line: 12 Position: 48]
Additional information: The text associated with this error code could not be found.
Here is the xaml code for the user control :
<UserControl
x:Class="SuperCards.CardPackItemListView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:SuperCards"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="125"
d:DesignWidth="400" >
<Border CornerRadius="2" BorderThickness="1" BorderBrush="White">
<Grid Background="White" Height="Auto" Width=" Auto">
<TextBlock x:Name="cardPackItemNameDisplay" HorizontalAlignment="Left" VerticalAlignment="Top" Width="Auto" Height="Auto" Text="(Sample) Periodic Table" Foreground="Gray" Margin="9,9,0,0" FontSize="30" />
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Margin="9,30,9,9" Width="Auto" Height="9" Background="gray" >
<Rectangle HorizontalAlignment="Left" VerticalAlignment="Stretch" Fill="Red" Width="46"/>
</Grid>
<TextBlock HorizontalAlignment="Right" VerticalAlignment="Top" Text="36" Foreground="Gray" Margin="0,9,9,0" FontSize="30"/>
</Grid>
</Border>
and here visual studios notified that the exception was not handled at the initializing component inside the constructor of the user control.
The following attribute on line 12 corresponds with the line in the error message; remove the leading space within the quotes:
Width=" Auto"
This may also cause problems if color names in WinRT are case sensitive; best to capitalize the G in Gray just in case:
Background="gray"

Looks like you are using Image from Your Computer.Please add image in your project with Build type Content.then give correct path as :
ImageSource="/Resources/Images/yourImage.png //if you added image in `Resource/Image` folder.
Hope this Helps.Cheers.
Check if the build action is set to "content". That might be causing the issue.
And also check the path of the image that you are using. It has to be inside your project. Ideally inside the assets folder. or somewhere separately.
Hope it helps. Cheers.
Don't add your PC address. It won't run on emulator. Since the address isn't resolved. Add the background image in the Assets or any folder in your solution then use
ImageSource = "Assets/background.png"
Assuming you have image in Assets folder named background.png
I want to use a usercontrol I found on the web in my WPF application. The thing is that I don't want to have to put it in a user control library and build it and then reference that. I just want to be able to import the files into my project and use it from there.
So what I have done is dragged the files into the solution explorer, and it added them okay. I then changed the namespaces to match my own and then attempted to add it to the main forms xaml(This is where my issue is.)
It says the type "local:Pie" is not found. Verify that you are not missing an assembly reference...and you know the rest.
Here is how I am calling it on my main for xaml:
<Grid>
<local:Pie Value="0" x:Name="pieChart" HorizontalAlignment="Center" Width="400" VerticalAlignment="Center" Margin="10"/>
<StackPanel HorizontalAlignment="Left" Margin="30,0,50,0" VerticalAlignment="Center">
<Slider Orientation="Vertical" Minimum="0" Maximum="1" TickFrequency="0.01" Height="272" ValueChanged="Slider_ValueChanged_1" Value="0" Name="slider"/>
</StackPanel>
</Grid>
Here is the controls XAML with my application namespace added:
<UserControl x:Class="MyApplicationNAmespace.Pie"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300" Loaded="UserControl_Loaded_1" SizeChanged="UserControl_SizeChanged_1">
<Grid>
<Ellipse Name="bgCircle"/>
<Path Name="path" StrokeThickness="1.5" Margin="0"/>
<Ellipse Name="hole" RenderTransformOrigin="0.5,0.5">
<Ellipse.RenderTransform>
<ScaleTransform ScaleX="0.45" ScaleY="0.45"/>
</Ellipse.RenderTransform>
</Ellipse>
<Label Content="Value" HorizontalAlignment="Center" VerticalAlignment="Center"
FontFamily="Segoe UI Light" FontSize="38" Name="lblValue"
VerticalContentAlignment="Center" HorizontalContentAlignment="Center"/>
</Grid>
</UserControl>
For the codebehind of the control all I have changed was the namespace to match my projects namespace.
Can anyone tell me what I am doing wrong? Thank you.
I've been trying to add a simple TextBlock control to my Windows Phone 8 app, however once I assign it a name in the GUI XAML editor and attempt to access the control via its assigned name in the C# code at runtime I get "NullReferenceExceptions" because the variable is never set.
I have narrowed the problem down to the PhoneApplicationPage method "FindName" i.e.
PhoneApplicationPage.FindName("videoName");
However a call like this to some of my controls (created in the GUI editor) simply return null. Has anybody had this problem and found a fix?
Regards.
The contents of the InitialiseComponent() method:
public void InitializeComponent() {
if (_contentLoaded) {
return;
}
_contentLoaded = true;
System.Windows.Application.LoadComponent(this, new System.Uri("/Youtube%20Downloader;component/MainPage.xaml", System.UriKind.Relative));
this.LayoutRoot = ((System.Windows.Controls.Grid)(this.FindName("LayoutRoot")));
this.TitlePanel = ((System.Windows.Controls.StackPanel)(this.FindName("TitlePanel")));
this.ContentPanel = ((System.Windows.Controls.Grid)(this.FindName("ContentPanel")));
this.videoName = ((System.Windows.Controls.TextBlock)(this.FindName("videoName")));
this.videoImage = ((System.Windows.Controls.Image)(this.FindName("videoImage")));
}
(The videoName and videoImage controls are the ones not getting added)
The XAML code is (that the editor has generated):

I had the same problem. Clean project will fix it.
