设置用户控件的样式 [英] Set Style for user control

问题描述

我正在尝试为我的用户控件设置样式.UserControl 在Controls"项目中，主题在MainProject"项目中

I am trying to set a style for my user control. The UserControl is in a project "Controls" and the theme is in a project "MainProject"

<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>

推荐答案

就我所见，这应该工作正常.您是否收到任何特殊警告或错误，或者样式中的某些部分没有得到应用?

That should be working fine as far as I can see. Do you get any special warnings or errors or do some parts from the Style not get applied?

要在设置Resources后设置样式，可以使用以下语法

To set the Style after Resources has been set, you can use the following syntax

<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，您可以将其与我在此处上传的示例应用程序进行比较:http://www.mediafire.com/?q1v98huubzw02zb
