我的C＃WPF应用程序中的数据网格存在布局问题。如果我的数据网格的内容无法显示在我的数据网格中，因为有很多行，则会显示一个滚动查看器（和滚动条）。这是正确的方式，我很高兴。更改WPF Datagrid中滚动条的位置
问题是，我的数据网格scrollviewer的位置是错误的。滚动查看器从标题行开始，但滚动条显示在我的内容的第一行。在标题中有一个白色的纠结。这是因为我的数据网格的背景是白色的。但是我的标题背景是灰色的。
我上传了一张带有红色箭头的图片，以说明我的问题。白色的retangle看起来真的很丑，所以我认为这是更好的方式来改变scrollviewer的位置，所以它开始在内容的第一行。也许有另一种可能性来解决这个问题？

最好的问候， 闪光
你可以让你自己的风格为您的数据网格，这里是共混物制成有两个变化
风格看看这两个变化
为PART_VerticalScrollBar - >Grid.Row="0"和Grid.RowSpan="2" 并为网格持有PART_HorizontalScrollBar - >Grid.ColumnSpan="2"
下面是完整的风格

希望这有助于
我一直讨厌那个角落。最简单的方法是将您的DataGrid.Background颜色设置为任何标题颜色，但如果它具有固定尺寸，这也会将空白的背景着色为DataGrid。您可以随时避免放置您DataGrid不舒展它控制里面的孩子，就像一个StackPanel，或LastChildFill="False"
<DockPanel LastChildFill="False">
<DataGrid ItemsSource="{Binding MyCollection}" Background="Silver" />
</DockPanel>
替代品包括覆盖样式或DataGrid的模板件或者它的滚动条一个DockPanel。凌乱，但可能。
附上您的数据网格中的ScrollViewer及其horizontalScrollBarVisibility设置为隐藏 和VerticalScrollBarVisibility到Auto.Hope这将帮助。
