设置用户控件的样式

Question

我正在尝试为我的用户控件设置样式.UserControl位于项目"控件"中,主题位于项目"MainProject"中

<UserControl x:Class="Controls.OutputPanel"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        mc:Ignorable="d" 
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        x:Name="OutputControl"> 
   <!-- Style="{DynamicResource UserControlStyle}"> - I cant set the style here because the Resource Dictionary hasn't been defined yet -->

    <UserControl.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/MainProject;component/Themes/MyTheme.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </UserControl.Resources>

    <!-- Now that the Resource Dictionary has been defined I need to set the style -->      

    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>

        <TextBox x:Name="textbox" 
                   ScrollViewer.VerticalScrollBarVisibility="Visible"
                   Text="{Binding ElementName=OutputControl, Path=TextProperty}"
                   IsReadOnly="True"
                   Style="{DynamicResource OutputTextBoxStyle}"/>

    </Grid>

</UserControl>

Answer 1

就我所见,那应该是正常的.您是否收到任何特殊警告或错误,或者是否未应用Style？

要设置设置后的样式Resources,可以使用以下语法

<UserControl.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/MainProject;component/Themes/MyTheme.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</UserControl.Resources>
<UserControl.Style>
    <DynamicResource ResourceKey="UserControlStyle"/>
</UserControl.Style>

如果您在此之后仍然遇到问题,可以将其与我在此处上传的示例应用进行比较:http://www.mediafire.com/？q1v98huubzw02zb
