根据所选选项卡更改 Tabcontrol 外部的控件属性

Question

我正在 WPF 中使用 tabcontrol。我希望 tabcontrol 之外的按钮根据某些选择（选择的标签页）更改为下拉按钮（组合框）感谢您的帮助。

将这两个控件添加到您的布局并根据数据触发器和选项卡控件的选定索引切换它们的可见性

    <ComboBox>
        <ComboBox.Style>
            <Style TargetType="ComboBox">
                <Setter Property="Visibility" Value="Collapsed"/>
                <Style.Triggers>
                    <DataTrigger Binding="{Binding ElementName=yourTabControl, Path=SelectedIndex}" Value="0">
                        <Setter Property="Visibility" Value="Visible"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </ComboBox.Style>
    </ComboBox>
    <Button>
        <Button.Style>
            <Style TargetType="Button">
                <Setter Property="Visibility" Value="Visible"/>
                <Style.Triggers>
                    <DataTrigger Binding="{Binding ElementName=yourTabControl, Path=SelectedIndex}" Value="1">
                        <Setter Property="Visibility" Value="Collapsed"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </Button.Style>
    </Button>
