Question

In a Windows Phone 7 project I’m using XAML that looks like this;

<phone:PhoneApplicationPage.Resources>
    <ValueConverters:FuelTypeEnumToRadioButtonConverter x:Name="fuelConverter" />
</phone:PhoneApplicationPage.Resources>

and further down on my Page I’m using it like this:

<RadioButton IsChecked="{Binding PreferredFuel, Mode=TwoWay, ConverterParameter=Blyfri95, Converter={StaticResource fuelConverter}}"  Content="Blyfri 95" Height="72" HorizontalAlignment="Left" Margin="-1,276,0,0" Name="radioButton1" VerticalAlignment="Top" GroupName="FuelType" />
<RadioButton IsChecked="{Binding PreferredFuel, Mode=TwoWay, ConverterParameter=Blyfri98, Converter={StaticResource fuelConverter}}" Content="Blyfri 98" Height="72" HorizontalAlignment="Left" Margin="154,276,0,0" Name="radioButton2" VerticalAlignment="Top" GroupName="FuelType" />
<RadioButton IsChecked="{Binding PreferredFuel, Mode=TwoWay, ConverterParameter=Diesel, Converter={StaticResource fuelConverter}}" Content="Diesel" Height="72" HorizontalAlignment="Left" Margin="308,276,0,0" Name="radioButton3" VerticalAlignment="Top" GroupName="FuelType" />

This all works fine and dandy in the actual application, but the XAML editor in Visual Studio complains that “Cannot register duplicate Name ‘fuelConverter’ in this scope“. I have to comment out the initial Resource-line to get the XAML designer working in Visual Studio 2010 (but then the application doesn’t work when I run it).

Anyone else seen this? Is this just a bug with the XAML designer?

Answer 1

shouldn’t that be:

<ValueConverters:FuelTypeEnumToRadioButtonConverter x:Key="fuelConverter" />

using x:Key instead of x:Name ?

Not sure why you get that error, though.
