如何在滚动时阻止WPF数据网格自动选择行

below is my datagrid's definition:

下面是我的datagrid的定义：

<DataGrid
    Name="ODataGrid"
    AutoGenerateColumns="False"
    Grid.Row="0"
    Grid.Column="0"
    CanUserAddRows="False"
    AlternationCount="2"
    HeadersVisibility="All"
    IsReadOnly="True"                               
    SelectionUnit="FullRow"
    HorizontalAlignment="Stretch"
    VerticalAlignment="Stretch"
    Background="#EBF0F0"
    AlternatingRowBackground="#E9E8EF"
    HorizontalGridLinesBrush="#7F7F7F"
    VerticalGridLinesBrush="#7F7F7F"
    SelectedItem="{Binding vmItem}"
    CellStyle="{StaticResource ODataGridCellStyle}"
    ItemsSource="{Binding vmResults}"
    Tag="{Binding DataContext, ElementName=BaseGrid}">

Below are the steps I took to get the error.

以下是我为获取错误而采取的步骤。

The first row was selected by default.
默认选择第一行。
I select another row in the datagrid.
我在datagrid中选择另一行。
I do a sort by clicking on one of the column header.
我点击其中一个列标题进行排序。
I do a scroll by dragging the vertical scroll bar.
我通过拖动垂直滚动条来滚动。
The initial first row was somehow auto selected.
最初的第一行以某种方式自动选择。
So now, there are 2 rows being selected.
所以现在，有两行被选中。

Why this behaviour? Anyway to prevent the auto select on scroll? Thanks.

为什么会这样？无论如何要阻止自动选择滚动？谢谢。
