I created a brand new Custom Control Library (WPF), and am trying to use it from another class library (not a WPF project). I get this error:
System.Windows.Markup.XamlParseException: 'Could not load file or
assembly 'CustomControls, PublicKeyToken=null' or one of its
dependencies. The system cannot find the file specified.'
From the XAML that is referencing the custom control library:
<Window
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:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:myNamespace="clr-namespace:CustomControls;assembly=CustomControls"
x:Class="MyCommandWindow.Ui"
mc:Ignorable="d"
Title="My Command" Height="710" Width="960" WindowStartupLocation="CenterScreen"
Background="White"
Foreground="Gray"
FontSize="12"
Name="CommandWindow" Loaded="CommandWindow_Loaded">
The custom control library reference is added to the class library.
Am I missing any steps?

I'm having a problem creating a viewmodel grid manually in Catel for a Catel usercontrol. The documentation implies that by naming the content grid "__catelInnerWrapper" that the content will not be wrapped with another grid by the ViewModelWrapperService and will use my grid instead. I'd like to do so for visual state management purposes. Using Snoopwpf I can see that the usercontrol is still being wrapped.
(https://i.imgur.com/teSu9La.png)
I tried creating a new Catel project template using Catel 5.8.0 and also 5.9.0 beta 0 using .NET 4.6.1 with a single usercontrol in the mainwindow to test a simplified application and saw the same behavior.
<catel:UserControl x:Class="CatelTest.Views.MyUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:catel="http://schemas.catelproject.com">
<Grid x:Name="__catelInnerWrapper">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="{Binding Title}" />
<Label Grid.Row="1" Content="My User Control" />
</Grid>
</catel:UserControl>
In stepping through ViewModelWrappingService.xaml.cs code it seems the usercontrol content Name property is always resolving to null and thus isn't matched with the InnerWrapperName. Do you know why this might be happening? Thank you
When looking at the source, you are doing the correct thing. If you are 100% sure that:
You are using a correct build (e.g. fully rebuilt app, not a
wrong configuration)
Snoop is correct
Then please report an issue (with minimal repro) at https://github.com/catel/catel/ and we will make sure it will be fixed in Catel 5.9 (currently in beta, about to be released but we will wait for this one).
I have some Styles-Files.
For example ButtonStyles.xaml looks like this:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style
x:Key="CustomButtonStyle"
TargetType="Button">
<Setter
Property="Foreground"
Value="White" />
<Setter
Property="Background"
Value="Black" />
<Setter
Property="Height"
Value="32" />
</Style>
<Style
TargetType="Button"
BasedOn="{StaticResource CustomButtonStyle}">
</Style>
</ResourceDictionary>
And I have Pages which extend from my BasePage.
If I want my new Styles to override the controls I have to add this Code in every Page:
<Page.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="../Styles/ButtonStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Page.Resources>
However if I have this code in my BasePage it won't theme my controls.
Is there a way to import my styles in every Page without copy-pasting this code over and over?
I can't reproduce this issue with using BasePage in my side. It would be better if you can post a sample that can reproduce your issue.
However, to use the custom styles in every page, I recommend merging resource dictionaries into Application.Resources. Application.Resources is the best place to put any app-specific resources that are referenced by multiple pages in your app's navigation structure. If the requested resource is not found in the Page.Resources, the XAML resources system will tries to check the Application.Resources property. So if we merged resource dictionaries into Application.Resources, we can use them in all pages of the app. And if we want to use some different styles in certain pages, we can specify new Style in their Page.Resources. For more information, see Lookup behavior for XAML resource references.
So we can merge resource dictionaries into Application.Resources like following:
(Note that ../Styles/ButtonStyles.xaml can't be used in WinRT XAML, we should use "/" to refer to the package root.)
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Styles/ButtonStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Then in other pages, if we don't specify the Style for Button, it will use the style defined in ButtonStyles.xaml.
I am creating an universal application using Visual Studio Ultimate 2013 Version 12.0.30501.00 Update 2. I am getting Catastrophic failure on adding Map Control in my xaml like this
<Maps:MapControl Visibility="Collapsed"/>.
I have added
xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps"
in the page header and added 'location' capability to application manifest file.
Has anyone faced the same issue?
You can test his by creating a sample application and add only MapControl. Please help me to resolve this issue.
The problem is observed in normal Windows Phone 8.1 applications also. Am i missing something here?
The problem is observed when i try to run the application in emulator.
The error does not show any other information just 'catastropic failure', nothing else.
May be i will try to re-install Visual Studio. But one more interesting fact is that i could get it working if i am not hiding the map control in the page.
Can you test it by creating a sample application and just making the map control Visibility='Collapsed'?
<Page
x:Class="TestMaps.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TestMaps"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid>
<Maps:MapControl Visibility="Collapsed" />
</Grid>
</Page>
And the problem is observed in more than one PC.
I've tested your example and indeed there is such a problem also on my Phone.
As I have checked it is possible to set Collapsed from code - so as a workaround:
<Grid>
<Maps:MapControl Name="myMap" Visibility="Visible" />
</Grid>
In the code behind:
public MainPage()
{
this.InitializeComponent();
this.Loaded += (sender, e) => myMap.Visibility = Visibility.Collapsed;
}
I've come up with a workaround for this. Instead of using visibility you can use the maps height/width properties to hide/show the map. Set them to 0 when you want to hide it, and set it to the parents width/height when you want to show it. Here is a code sample:
<Page
x:Class="WP81App.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:WP81App"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid>
<Maps:MapControl Name="MyMap" Height="0" Width="0" />
<Button Content="Show Map" Click="ShowMapBtn_Clicked" HorizontalAlignment="Center"/>
</Grid>
</Page>
Button Handler:
private void ShowMapBtn_Clicked(object sender, RoutedEventArgs e)
{
var mapContainer = MyMap.Parent as FrameworkElement;
MyMap.Width = mapContainer.ActualWidth;
MyMap.Height = mapContainer.ActualHeight;
//Hide the button
(sender as Button).Visibility = Visibility.Collapsed;
}
I want to write a custom control that's used like this:
<HorizontalTick>Some string</HorizontalTick>
It should render like this:
-- Some string -------------------------------------------
Here's my code:
<UserControl x:Class="WeatherDownloadDisplay.View.HorizontalTick"
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:DesignWidth="348"
Name="controlRoot">
<DockPanel LastChildFill="True">
<UserControl VerticalAlignment="Center" BorderBrush="Black" BorderThickness="1" Width="10"/>
<Label Content="???" />
<UserControl VerticalAlignment="Center" BorderBrush="Black" BorderThickness="1"/>
</DockPanel>
</UserControl>
It works except for the label binding. Can someone help me fill in the question marks? I thought about using a ContentPresenter but it seems like an inline binding would be best.
-Neal
The binding would be:
<Label Content="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=Content}" />
However, reconsider using a ContentPresenter to be able to show any content directly rather than adding a label that will use its own ContentPresenter to show it.
That being said, you could also replace your whole control by a simple ContentControl with a ContentTemplate showing the lines and the inner content.
I am trying to define a window template that can be used by windows in other assemblies. I define a window template and store it in resource dictionary in some assembly. After, I use this template in other assembly on window definition in XAML. It looks that the template is accepted and I can see updated window in VS-2010 designer but when I add a new control to this window, the control disappears from window but still exists in XAML code. I also tried to apply the same template explicitly and it works well.
Xaml code of generic.xaml in project that contains template definition, the ThemeInfo attribute is set and BuildAction property for this file is Page.
<ControlTemplate x:Key="{ComponentResourceKey TypeInTargetAssembly= {x:Type local:DialogResources}, ResourceId=DialogTemplate}">
<Border Width="Auto" Height="Auto" Name="windowFrame"
BorderBrush="#395984"
BorderThickness="1"
CornerRadius="0,20,20,20"
Background="AliceBlue">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<TextBlock Margin="1" Padding="5" Text="Template Window" FontWeight="Bold"/>
<Border Background="#B5CBEF" Grid.Row="1" CornerRadius="0,0,20,20" >
<AdornerDecorator>
<ContentPresenter/>
</AdornerDecorator>
</Border>
</Grid>
</Border>
</ControlTemplate>
DialogRespources - is an empty class that defined in MyProg.Resources assembly.
Now I use this template in other assembly like this:
In this window I add a button but I can't to see it. When I define the TemplateControl explicitly (without using resource) I can see it.
The other problem is that I get a following designer exception when use TargetType="{x:Type Window}" for template in resource: "'Window' ControlTemplate TargetType does not match templated type 'WindowInstance'." I could not find anything regarding this exception in Google.
Please, help me to understand what is wrong in my code?
