c# – 当画笔用作背景时,如何从WPF重复按钮中删除边框和效果

我遇到的问题是,无论我尝试什么,按钮周围仍然有一个白色矩形,而且,我不确定现在看了几个小时之后,我确信我理解为什么或如何删除它.

我在XAML中使用以下内容创建了按钮

<RepeatButton Content="" BorderThickness="0" HorizontalAlignment="Left" Margin="334,265,0" VerticalAlignment="Top" Width="149" Height="100" Background="{DynamicResource ImageBrush_Decrement}" Style="{DynamicResource RepeatButtonStyle_noflash}" d:LayoutOverrides="HorizontalAlignment"/>

你会注意到我引用了一个“RepeatButtonNoFlash”样式,我用它来删除defaultrender(因为它引起了闪烁效果,这种样式在共享字典中定义如下

<ResourceDictionary
