设置用户控件子控件的样式
假设我有一个像这样的用户控件:
<UserControl x:Class="StyleTest.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Button Grid.Row="0">Style please</Button>
<Button Grid.Row="1">Style please</Button>
</Grid>
我想将此控件中的所有按钮设置为背景=绿色。 但我不想影响程序中的其他按钮,也不想修改控件的代码。
我现在发现的是这样的:
<Window x:Class="StyleTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:loc="clr-namespace:StyleTest"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style x:Key="UserControlStyles" TargetType="Button">
<Setter Property="Background" Value="green" />
</Style>
</Window.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Button Grid.Column="0">no Style please</Button>
<loc:UserControl1 Grid.Column="1">
<loc:UserControl1.Resources>
<Style TargetType="Button" BasedOn="{StaticResource UserControlStyles}" />
</loc:UserControl1.Resources>
</loc:UserControl1>
</Grid>
但这意味着如果我还想设置文本框的前景色等样式,我必须将此代码添加到控件的每个实例中,以及一些额外的代码。
我正在寻找与此类似的东西:
<Style TargetType="Buttons that are childs of UserControl1">
<Setter Property="Background" Value="green" />
</Style>
有办法做到这一点吗?
我认为控件模板还不够,因为我不想重新设计整个控件,我只想设置按钮的颜色。
Say I have a user control like this:
<UserControl x:Class="StyleTest.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Button Grid.Row="0">Style please</Button>
<Button Grid.Row="1">Style please</Button>
</Grid>
And I want to set all buttons in this control to background=green.
But I don't want to affect other buttons in my program and I don't want to modify the code of the control.
What I found right now is this:
<Window x:Class="StyleTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:loc="clr-namespace:StyleTest"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style x:Key="UserControlStyles" TargetType="Button">
<Setter Property="Background" Value="green" />
</Style>
</Window.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Button Grid.Column="0">no Style please</Button>
<loc:UserControl1 Grid.Column="1">
<loc:UserControl1.Resources>
<Style TargetType="Button" BasedOn="{StaticResource UserControlStyles}" />
</loc:UserControl1.Resources>
</loc:UserControl1>
</Grid>
But this would imply that I have to add this code to every instance of the control, and some extra code, if I want to style e.g. foreground color of TextBoxes also.
What I am looking for is something similar to this:
<Style TargetType="Buttons that are childs of UserControl1">
<Setter Property="Background" Value="green" />
</Style>
Is there a way of doing this?
I don't think that a control template would be sufficient, because I don't want to redesign the whole control, I just want to set the color of the buttons.

在 App.xaml 中,您可以添加此样式,该样式将应用于 UserControl1 的所有实例
In App.xaml you could add this style which will be applied to all instances of UserControl1
如果我理解正确,您只需要修改您的 UserControl 以便在其中添加样式,而不是在 Window 控件中
我刚刚看到您说您不想修改该控件。你的意思是你不能修改UserControl的xaml?为什么不呢?
If I understand correctly, you just need to modify your UserControl so that you add the style there, instead of in the Window control
I just saw that you said you don't want to modify the control. You mean that you can't modify the xaml of the UserControl? Why not?
