选中WPF TextBox边框？

Question

我想让一个WPF TextBox有一个DarkBlue边框,厚度等于1.我想让WPF有这个边框(DarkBlue,厚度设置为1),即使选中TextBox也是如此.

我尝试通过以下代码执行此任务.但是,它根本不起作用.任何想法或提示？任何帮助将不胜感激.

  <Style x:Key="ReadOnlyLargeTextBox" TargetType="{x:Type TextBox}" >
        <Setter Property="Height" Value="80"/>
        <Setter Property="MaxHeight" Value="80"/>

        <Setter Property="VerticalScrollBarVisibility" Value="Visible"/>
        <Style.Triggers>
            <Trigger Property="TextBox.IsMouseOver"    Value="True">
                <Setter Property="BorderBrush" Value="DarkBlue"/>
                <Setter Property="BorderThickness" Value="1"/>
            </Trigger>
            <Trigger Property="TextBox.IsMouseOver"    Value="False">
                <Setter Property="BorderBrush" Value="DarkBlue"/>
                <Setter Property="BorderThickness" Value="1"/>
            </Trigger>
        </Style.Triggers>


    </Style>

PS请注意,文本框没有IsSelected属性.

只是看到你想要的......

<Style x:Key="TextBoxStyle1" BasedOn="{x:Null}" TargetType="{x:Type TextBox}">
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Padding" Value="1"/>
        <Setter Property="AllowDrop" Value="true"/>
        <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TextBox}">
                <Border x:Name="bg" BorderBrush="#FF825E5E" BorderThickness="1">
                        <ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                        </Border>
                    <ControlTemplate.Triggers>

                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="BorderBrush" TargetName="bg" Value="DarkBlue"/>
                            <Setter Property="BorderThickness" TargetName="bg" Value="2"/>
                        </Trigger>
                        <Trigger Property="IsFocused" Value="True">
                            <Setter Property="BorderBrush" TargetName="bg" Value="DarkBlue"/>
                            <Setter Property="BorderThickness" TargetName="bg" Value="2"/>
                        </Trigger>

                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

我认为您的问题是由于 Trigger 属性值包含TextBox。您只需要该房产的名称。

    <Style x:Key="ReadOnlyLargeTextBox" TargetType="{x:Type TextBox}">
        <Setter Property="Height" Value="80"/>
        <Setter Property="MaxHeight" Value="80"/>

        <Setter Property="VerticalScrollBarVisibility" Value="Visible"/>

        <Style.Triggers>
            <Trigger Property="IsFocused"  Value="True">
                <Setter Property="BorderBrush" Value="Blue"/>
                <Setter Property="BorderThickness" Value="1"/>
            </Trigger>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="BorderBrush" Value="Blue"/>
                <Setter Property="BorderThickness" Value="1"/>
            </Trigger>
        </Style.Triggers>
    </Style>
