I am using WPF datagrid, only modification I have in place is:

```
    <toolkit:DataGridTextColumn.ElementStyle>
       <Style TargetType="TextBlock">
       <Setter Property="TextWrapping" Value="Wrap"/>
      </Style>
    </toolkit:DataGridTextColumn.ElementStyle>

```

I have this modification so if the cell contents are longer, they stretch the line height, no text is hidden.
Problem is with DataGrid's scrolling behaviour - it jumps whole lines when scrolling, which does not work well at all if the row is higher than one line - scrollbar is jerking on scrolling etc.

Is there any way to make WPF DataGrid scroll "smoothly" and not line by line?

Thanks
