WP7 Toolkit AutoCompleteBox 在 Pivot and Panorama无法正常显示的解决方案

在官方Issue Tracker 有人提出这个BUG

主要说了牛人 Jeff Wilcox 提供了解决方案

最好下载：根据代码最好理解了

代码很多就不仔细说了;

复制Converters/VisibilityConverter.cs 到你的工程

然后在xaml 里 OK 搞定！~

<Grid.Resources>

    <localControls:VisibilityConverter x:Key="Vis"/>

</Grid.Resources>

<ControlTemplate TargetType="toolkit:AutoCompleteBox">

    <Grid>

        <Grid.RowDefinitions>

            <RowDefinition Height="Auto"/>

            <RowDefinition/>

        </Grid.RowDefinitions>

        <TextBox

            x:Name="Text"

            Background="{TemplateBinding Background}"

            BorderBrush="{TemplateBinding BorderBrush}"

            BorderThickness="{TemplateBinding BorderThickness}"

            FontFamily="{TemplateBinding FontFamily}"

            FontSize="{TemplateBinding FontSize}"

            FontStyle="{TemplateBinding FontStyle}"

            FontWeight="{TemplateBinding FontWeight}"

            Foreground="{TemplateBinding Foreground}"

            InputScope="{TemplateBinding InputScope}"

            Opacity="{TemplateBinding Opacity}"

            Padding="{TemplateBinding Padding}"

            Style="{TemplateBinding TextBoxStyle}"/>

        <ListBox

            Margin="12"

            Visibility="{Binding Path=IsDropDownOpen, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource Vis}}"

            Grid.Row="1"

            x:Name="Selector"

            Background="White"

            FontFamily="{TemplateBinding FontFamily}"

            FontSize="{TemplateBinding FontSize}"

            FontStyle="{TemplateBinding FontStyle}"

            FontWeight="{TemplateBinding FontWeight}"

            Foreground="{TemplateBinding Foreground}"

            IsTabStop="False"

            ItemContainerStyle="{TemplateBinding ItemContainerStyle}"

            ItemTemplate="{TemplateBinding ItemTemplate}"

            Opacity="{TemplateBinding Opacity}"

            BorderBrush="{StaticResource PhoneTextBoxEditBorderBrush}"

            BorderThickness="{TemplateBinding BorderThickness}"

            Padding="0,8"/>

    </Grid>

</ControlTemplate>
