如何在wpf DataGrid中更改选定的行背景图像

Question

我的DataGrid包含以下代码。

在更改原生行背景中有我自己的图像。那么我也可以在所选行上更改行背景图像。

 <DataGrid x:Name="dtstandardview" BorderThickness="0" Height="429"  Width="688" BorderBrush="Aqua" MouseLeftButtonDown="dtstandardview_MouseRightButtonUp_1"
                     GridLinesVisibility="None" MouseRightButtonUp="dtstandardview_MouseRightButtonUp_1" 
                     VerticalScrollBarVisibility="Visible" AutoGenerateColumns="False" IsReadOnly="True" 
                      CanUserDeleteRows="False"  AlternationCount="2" CanUserResizeRows="False" Sorting="dtstandardview_Sorting_1"
                     Background="#DCDCDC" HeadersVisibility="Column" CanUserResizeColumns="False"
                      RowHeight="27" SelectionUnit="FullRow" CanUserAddRows="False" MinRowHeight="27" LoadingRow="dtstandardview_LoadingRow" LoadingRowDetails="dtstandardview_LoadingRowDetails" Loaded="dtstandardview_Loaded" Initialized="dtstandardview_Initialized" CellEditEnding="dtstandardview_CellEditEnding" AutoGeneratingColumn="dtstandardview_AutoGeneratingColumn" UnloadingRow="dtstandardview_UnloadingRow" UnloadingRowDetails="dtstandardview_UnloadingRowDetails"    >

            </DataGrid>

当我选择行时，我会在网格上获得以下效果。

我希望整行有浅蓝色。

Answer 1

您可以使用TemplateBinding

<Border Name="DataGridCellBorder"
        Background="{TemplateBinding Background}"/>

Answer 2

以前我遇到过同样的问题，所以我采用了以下方法，对我来说效果很好。一旦尝试......

您正在向网格顶部右侧指定一些宽度（您正在使用按钮）？只要给绑定元素即赋予相同的宽度，如果你使用的是 Textblock ，那么该宽度与它的标题相同。
