May someone please tell me that how one can set the scroll number of lines one at a time by c# code behind or by any property in WPF DataGrid.
I know we can set that property from control panel as well but i want that thing from program.
Scroll Bar Code( .Xaml)-
<Style x:Key="{x:Type ScrollBar}" TargetType="{x:Type ScrollBar}">
<Setter Property="Stylus.IsFlicksEnabled" Value="false" />
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrush}}" />
<Setter Property="Background" Value="{DynamicResource ScollBarBackgroundBrush}" />
<Setter Property="ScrollViewer.CanContentScroll" Value="False" />
<Setter Property="Width" Value="12" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollBar}">
<Border BorderBrush="#e7e7e7" BorderThickness="1">
<Grid x:Name="GridRoot"
Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidth}}"
Background="{TemplateBinding Background}">
<Grid.RowDefinitions>
<RowDefinition MaxHeight="18" />
<RowDefinition Height="0.00001*" />
<RowDefinition MaxHeight="18" />
</Grid.RowDefinitions>
<RepeatButton x:Name="DecreaseRepeat"

I got the answer. We just need to set CanContentScroll property to False.
ScrollViewer.CanContentScroll=False
