Cannot declare the resource key for the Converter in generic.xaml?

Question

Hi Guys,

I am not able declare the Resource key for the Converter in the generic.xaml file. It throws an exception like " Could not find %0 from the text %1". But i can do this in the Metro style application instead of class library. Does it mean Converter is restricted in generic.xaml ?. Or Am i wrong ?

Regards,
David C

Hi Tim,

 

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
                    xmlns:this="using:TestingDemo">

<this:TextConverter x:Key="conv" />

    <Style TargetType="this:Testing">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="this:Testing">
                    <Grid>
                        <Border />
                        <TextBlock x:Name="txt" Text="{Binding Path=Content,Converter={StaticResource conv}}"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
   
</ResourceDictionary>

 

When i use this lines in my custom control. It throws an exception.

This is helpful.  Can you share the converter source (or perhaps a smaller repro)?  I'll log a bug for investigation once we have that.

Answer 5

Ok now I see.  You are getting an error about the type not found.  Yes right now the XamlMetaData is not being generated for types in resource dictionaries like that.  I think we already have this solved, but I will be logging a bug regardless just to make sure :-)

I have the same error in the Consumer Preview. Here is my code:

class Cls
{
    public Cls(){}
}

<ResourceDictionary    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:TestApplication">

    <local:Cls x:Key="resourceCls">        
    </local:Cls>
</ResourceDictionary>

 <Page.Resources>
        <ResourceDictionary Source="Dictionary1.xaml"/>
</Page.Resources>

Tim, this didn't help.

Answer 10

it seems to work for me. here is what I tried

<Page
    x:Class="Application3.BlankPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Application3"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">
    <Page.Resources>
        <ResourceDictionary Source="Dictionary1.xaml"/>
    </Page.Resources>
    <Grid Background="{StaticResource ApplicationPageBackgroundBrush}">
        <TextBlock DataContext="{Binding Source={StaticResource myClass}}" Text="{Binding DisplayValue}"/>
           </Grid>
</Page>

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Application3">
    <local:MyClass x:Key="myClass"/>
</ResourceDictionary>

 public class MyClass
    {
        public string DisplayValue { get; set; }
        public MyClass()
        {
            DisplayValue = "this is some text and more text";
        }
    }

Answer 11

Changing property of "Dictionary1.xaml" Build Action to "Page" solve this problem. This is very strange because other properties of resource files setted to "content".

Answer 12

@Sergey - ah were you working on an older project from Dev Preview?  All resource dictionary files now added/created to the project are marked as Page.  This is required to get XAML validation and code generation for any custom types used within those resource dictionaries.

Answer 13

Yes, you are right. This project was created in Dev Preview. 

Answer 14

Hi Tim,

Is this bug fix released?

Thanks

Answer 15

@Anatoli - ensure that your dictionary is marked as page is the fix.  This should already be the case when new projects/items are created in the consumer preview.
