WPF: Get Tag Property from ResourceDictionary-CodePudding

I'm assigning a text to Tag property of the Button but how can I use it from ResourceDictionary.

My Button:

<Button Style="{StaticResource ControlBarButton}" Tag="-"/>

I want to use Tag property from content of the button My Resource Dictionary:

<Style TargetType="Button"
       x:Key="ControlBarButton">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>

                <Button Width="35"
                        Content="I WANT TO USE `Tag` HERE">
                </Button>

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

CodePudding user response：

Use a TemplateBinding in the template:

<Style TargetType="Button" x:Key="ControlBarButton">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>

                <Button Width="35"
                        Content="{TemplateBinding Tag}">
                </Button>

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