Question

我在expander中有一个datagrid，gatagrid具有10列以上。然后datagrid在扩展器中
应该滚动。但是它不能滚动以查看其他列。我的代码在下面。

                <Expander Header="Attribute" VerticalAlignment="Top" Grid.Row="1" >
                    <ScrollViewer HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Visible" CanContentScroll="True" Grid.Row="1" >
                           <DataGrid DataContext="{Binding}" Height="257" ItemsSource="{Binding}"  MinHeight="200" Name="gridview1" Grid.Row="2" Grid.Column="0" 
                           VerticalAlignment="Bottom" IsReadOnly="True"></DataGrid>
                     </ScrollViewer>
                </Expander>

datagrid在其ControlTemplate中嵌入了scrollViewer。

因此您可以做两件事：

如果您真的想使用自己的scrollviewer（但是请注意，这样做会丢失诸如datagrid虚拟化之类的功能），此代码应起作用：

<Expander Header="Attribute" VerticalAlignment="Top" Grid.Row="1" >
    <ScrollViewer HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible" CanContentScroll="False" Grid.Row="1" >
        <DataGrid Height="257"  MinHeight="200" Name="gridview1" Grid.Row="2" Grid.Column="0" 
                       VerticalAlignment="Bottom" IsReadOnly="True">
            <DataGrid.Style>
                <Style>
                    <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" />
                    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Disabled" />
                </Style>
            </DataGrid.Style>
        </DataGrid>
    </ScrollViewer>
</Expander>

但是，我建议您仅此操作：

<Expander Header="Attribute" VerticalAlignment="Top" Grid.Row="1" >
        <DataGrid Height="257"  MinHeight="200" Name="gridview1" Grid.Row="2" Grid.Column="0" VerticalAlignment="Bottom" IsReadOnly="True">
            <DataGrid.Style>
                <Style>
                    <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Visible" />
                    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Visible" />
                </Style>
            </DataGrid.Style>
    </DataGrid>
</Expander>

datagrid.style甚至不需要。
