WPF Datagrid视图（在内容滚动数据丢失后显式将数据插入单元格）

Question

将数据插入WPF数据网格单元格后显式滚动内容时，数据从单元格中丢失

我插入的数据从单元格消失

     <DataGrid AllowDrop="True" 
                  AlternatingRowBackground="White" AutoGenerateColumns="True"
                  Background="#FFDBF7FC" BorderBrush="#FF2374A0" 
                  BorderThickness="2" CanUserReorderColumns="True"
                  HorizontalGridLinesBrush="#FF041D31" 
                  Margin="17,173,0,-414" x:Name="DashBoardGrid" 
                  RowBackground="#FFDBF7FC" 
                  ScrollViewer.CanContentScroll="False" 
                  ScrollViewer.HorizontalScrollBarVisibility="Auto"
                  ScrollViewer.VerticalScrollBarVisibility="Disabled" 
                  VerticalGridLinesBrush="#FF041D31" 
                  SelectedIndex="0" HorizontalAlignment="Left" 
                  Width="929" />



int columnno = Convert.ToInt32(ColumnNo.Text); 
        int Finalcolumn = columnno - 1; 
        int count = DashBoardGrid.Items.Count;

        for (int i = 0; i < count - 1; i++)
        {
            DataGridHelper.GetCell(DashBoardGrid, i, Finalcolumn).Content = AutofillValue.Text;
        }
