[Solved] Unhandled exception and application crash after update to 2012.2 607

[OTMOP]

Hello.

First of all sorry for my bad english.

In my app I have a style for RadListPicker.

<Style TargetType="telerikInput:RadListPicker">
        <Setter Property="PopupStyle">
            <Setter.Value>
                <Style TargetType="telerikPrimitives:RadSelector">
                    <Setter Property="Foreground" Value="{StaticResource ForegroundBrush}" />
                    <Setter Property="Background" Value="{StaticResource ChromeBrush}"/>
                </Style>
            </Setter.Value>
        </Setter>
        <Setter Property="HeaderStyle">
            <Setter.Value>
                <Style TargetType="ContentControl">
                    <Setter Property="HorizontalAlignment" Value="Left" />
                    <Setter Property="VerticalAlignment" Value="Center" />
                    <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeNormal}" />
                    <Setter Property="Foreground" Value="{StaticResource LightAccentForegroundBrush}" />
                    <Setter Property="Margin" Value="0, 0, 0, 8" />
                </Style>
            </Setter.Value>
        </Setter>
    </Style>


All custom resources (brushes, colors, etc) are declared. This style worked perfect in 2012.1 321 version, but after update to 2012.2 607 my app is crashing in runtime with following exceptions:

A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in System.Windows.dll
A first chance exception of type 'System.Exception' occurred in System.Windows.dll
A first chance exception of type 'MS.Internal.WrappedException' occurred in System.Windows.dll

A first chance exception of type 'MS.Internal.WrappedException' occurred in System.Windows.dll
A first chance exception of type 'MS.Internal.WrappedException' occurred in System.Windows.dll


It seems that problem is in PopupStyle declaration. If I remove it then application works well, but I need PopupStyle. Any ideas?

Hello,

We are aware of this change and it is documented as a breaking change in our release notes for Q2.2012.
If you use custom style for the ListPicker PopupStyle you should change it to be similar to this:

<Setter Property="PopupStyle">

<Setter.Value>

<Style TargetType="telerikPrimitives:RadDataBoundListBox">

<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeExtraLarge}" />

<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiLight}" />

<Setter Property="Background" Value="{StaticResource PhoneChromeBrush}" />

<Setter Property="HorizontalAlignment" Value="Stretch" />

<Setter Property="VerticalAlignment" Value="Stretch" />

<Setter Property="CheckBoxStyle">

<Setter.Value>

<Style TargetType="telerikPrimitives:ItemCheckBox">

<Setter Property="VerticalAlignment" Value="Center" />

</Style>

</Setter.Value>

</Setter>

</Style>

</Setter.Value>

</Setter>
