WPF复选框自定义样式检查消失

wpf checkbox properties

WPF复选框自定义样式检查消失,wpf,checkbox,properties,styles,datatrigger,Wpf,Checkbox,Properties,Styles,Datatrigger,也许这是多余的，但我什么也找不到。我可能错过了一些简单的东西在选择事件的codebehind中设置有问题的复选框 chkEmpOK.IsChecked = _cfgUsr.IsEnabled; 在我尝试添加自定义样式之前，它一直按预期工作。现在，复选框显示文本，但复选框的图像/图示符/方框部分不显示。我想我在风格上做错了什么。以下是XAML中的控件和样式： <CheckBox x:Name="chkEmpOK" Grid.Column="2"

也许这是多余的，但我什么也找不到。我可能错过了一些简单的东西

在选择事件的codebehind中设置有问题的复选框

  chkEmpOK.IsChecked = _cfgUsr.IsEnabled;

在我尝试添加自定义样式之前，它一直按预期工作。现在，复选框显示文本，但复选框的图像/图示符/方框部分不显示。我想我在风格上做错了什么。以下是XAML中的控件和样式：

<CheckBox x:Name="chkEmpOK" Grid.Column="2" Grid.Row="4" Margin="10,10,0,0">
    <CheckBox.Style>
        <Style TargetType="{x:Type CheckBox}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type CheckBox}">
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsChecked" Value="False">
                                <Setter Property="Content" Value="Click Me to Enable"/>
                                <Setter Property="Foreground" Value="Red"/>
                            </Trigger>
                            <Trigger Property="IsChecked" Value="True">
                                <Setter Property="Content" Value="To remove access- click me"/>
                            </Trigger>
                        </ControlTemplate.Triggers>
                        <ContentPresenter Content="{TemplateBinding Content}"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </CheckBox.Style>
</CheckBox>

这就是它看起来的样子

希望我错过了一些简单的东西。它是否与从ToggleButton继承有关？

您正在使用自己的复选框样式覆盖原始的复选框样式，该样式没有与复选框相关的代码。导航到文档大纲窗口，右键单击复选框，然后编辑模板->编辑副本

然后，您可以将模板样式导入窗口资源并对其进行编辑：

<Window.Resources>
    <Style x:Key="FocusVisual">

                        <Trigger Property="IsPressed" Value="true">
                            <Setter Property="Background" TargetName="checkBoxBorder" Value="{StaticResource OptionMark.Pressed.Background}"/>
                            <Setter Property="BorderBrush" TargetName="checkBoxBorder" Value="{StaticResource OptionMark.Pressed.Border}"/>
                            <Setter Property="Fill" TargetName="optionMark" Value="{StaticResource OptionMark.Pressed.Glyph}"/>
                            <Setter Property="Fill" TargetName="indeterminateMark" Value="{StaticResource OptionMark.Pressed.Glyph}"/>
                        </Trigger>
                        <Trigger Property="IsChecked" Value="true">
                            <Setter Property="Opacity" TargetName="optionMark" Value="1"/>
                            <Setter Property="Opacity" TargetName="indeterminateMark" Value="0"/>
                            <Setter Property="Content" Value="To remove access- click me" />
                        </Trigger>
                        <Trigger Property="IsChecked" Value="false">
                            <Setter Property="Content" Value="Click Me to Enable" />
                        </Trigger>
                        <Trigger Property="IsChecked" Value="{x:Null}">
                            <Setter Property="Opacity" TargetName="optionMark" Value="0"/>
                            <Setter Property="Opacity" TargetName="indeterminateMark" Value="1"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

根据需要编辑相关触发器：

<Trigger Property="IsChecked" Value="true">
    <Setter Property="Opacity" TargetName="optionMark" Value="1"/>
    <Setter Property="Opacity" TargetName="indeterminateMark" Value="0"/>
    <Setter Property="Content" Value="To remove access- click me" />
</Trigger>
<Trigger Property="IsChecked" Value="false">
    <Setter Property="Content" Value="Click Me to Enable" />
</Trigger>

另一种方法是为框添加自己的代码。类似于带有边框和矢量图像的StackPanel。见下例：

<CheckBox x:Name="chkEmpOK" Margin="10,10,0,0">
        <CheckBox.Style>
            <Style TargetType="{x:Type CheckBox}">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type CheckBox}">
                            <StackPanel Orientation="Horizontal"
                                        SnapsToDevicePixels="True">
                                <Border Width="15"
                                        Height="14"
                                        BorderThickness="1"
                                        BorderBrush="DimGray"
                                        VerticalAlignment="Center"
                                        Background="{TemplateBinding Background}">
                                    <Viewbox Margin="1">
                                        <Path
                                            x:Name="ckeckMark"
                                            Fill="Black"
                                            Data="F1 M 9.97498,1.22334L 4.6983,9.09834L 4.52164,9.09834L 0,5.19331L 1.27664,3.52165L 4.255,6.08833L 8.33331,1.52588e-005L 9.97498,1.22334 Z " />
                                    </Viewbox>
                                </Border>
                                <ContentPresenter Margin="5 0 0 0" 
                                                  Focusable="False"/>
                            </StackPanel>
                            <ControlTemplate.Triggers>
                                <Trigger Property="IsChecked" Value="False">
                                    <Setter Property="Content" Value="Click Me to Enable" />
                                    <Setter Property="Foreground" Value="Red" />
                                    <Setter Property="Visibility" Value="Hidden" TargetName="ckeckMark" />
                                </Trigger>
                                <Trigger Property="IsChecked" Value="True">
                                    <Setter Property="Content" Value="To remove access- click me" />
                                    <Setter Property="Visibility" Value="Visible" TargetName="ckeckMark" />
                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </CheckBox.Style>
    </CheckBox>

另一种方法是使用选中和未选中事件设置复选框的内容和颜色。如果你的程序很大，考虑使用MVVM模式。

你正在重写原始的复选框样式，它自己没有与Box相关的代码。导航到文档大纲窗口，右键单击复选框，然后编辑模板->编辑副本

然后，您可以将模板样式导入窗口资源并对其进行编辑：

<Window.Resources>
    <Style x:Key="FocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <SolidColorBrush x:Key="OptionMark.Static.Background" Color="#FFFFFFFF"/>
    <SolidColorBrush x:Key="OptionMark.Static.Border" Color="#FF707070"/>
    <Style x:Key="OptionMarkFocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle Margin="14,0,0,0" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <SolidColorBrush x:Key="OptionMark.MouseOver.Background" Color="#FFF3F9FF"/>
    <SolidColorBrush x:Key="OptionMark.MouseOver.Border" Color="#FF5593FF"/>
    <SolidColorBrush x:Key="OptionMark.MouseOver.Glyph" Color="#FF212121"/>
    <SolidColorBrush x:Key="OptionMark.Disabled.Background" Color="#FFE6E6E6"/>

    <SolidColorBrush x:Key="OptionMark.Pressed.Border" Color="#FF3C77DD"/>
    <SolidColorBrush x:Key="OptionMark.Pressed.Glyph" Color="#FF212121"/>
    <SolidColorBrush x:Key="OptionMark.Static.Glyph" Color="#FF212121"/>
    <Style x:Key="CheckBoxStyle1" TargetType="{x:Type CheckBox}">

        <Setter Property="BorderBrush" Value="{StaticResource OptionMark.Static.Border}"/>
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Template">
            <Setter.Value>
