这个位置就是 这里

我们更改 DataGridControltemplate 模板

看树形结构 里面是一个BUtton

功能是全选 能找到了 那就直接改掉就可以

"DataGridControlTemplate1" TargetType="{x:Type DataGrid}">



        	"{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True">




        		"DG_ScrollViewer" Focusable="False">




        			




        				"{x:Type ScrollViewer}">




        					




        						




        							"Auto"/>




        							"*"/>




        							"Auto"/>




        						



        						




        							"Auto"/>




        							"*"/>




        							"Auto"/>




        						



        						"208" Height="125.917" Command="ApplicationCommands.SelectAll" Focusable="False" Style="{DynamicResource {ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}}">




        							




        								"HeadersVisibility" RelativeSource="{RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type DataGrid}}">




        									




        										All




        									



        								



        							



        						



        						"PART_ColumnHeadersPresenter" Grid.Column="1">




        							




        								"HeadersVisibility" RelativeSource="{RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type DataGrid}}">




        									




        										Column




        									



        								



        							



        						



        						"PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" CanHorizontallyScroll="False" Grid.ColumnSpan="2" CanVerticallyScroll="False" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Grid.Row="1"/>




        						"PART_VerticalScrollBar" Grid.Column="2" Maximum="{TemplateBinding ScrollableHeight}" Orientation="Vertical" Grid.Row="1" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}"/>




        						"1" Grid.Row="2">




        							




        								"{Binding NonFrozenColumnsViewportHorizontalOffset, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type DataGrid}}}"/>




        								"*"/>




        							



        							"PART_HorizontalScrollBar" Grid.Column="1" Maximum="{TemplateBinding ScrollableWidth}" Orientation="Horizontal" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportWidth}"/>




        						



        					



        				



        			



        			"{TemplateBinding SnapsToDevicePixels}"/>




        		



        	



        

改这个就可以

"208" Height="125.917" Command="ApplicationCommands.SelectAll" Focusable="False" Style="{DynamicResource {ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}}">



        							




        								"HeadersVisibility" RelativeSource="{RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type DataGrid}}">




        									




        										All
