Two question:
- How to disable drag thumb on a ScrollBar in WPF?
- Is there a way to limit drag thumb position? like LargeChange or SmallChange?
Two question:
Edit the template of the ScrollBar control and set the IsEnabled property of the Thumb to false
Not sure you can do that directly from code or XAML but you might add 2 new DP to a control which inherits the ScrollBar class and then change the template to have this new feature
Maybe it will be usefull for someone If you wanna disable drag thumb there two way:
Example:
<Style TargetType="{x:Type ScrollBar}">
<Setter Property="Background" Value="{StaticResource BackgroundColor}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollBar}">
<Grid x:Name="Bg" SnapsToDevicePixels="true">
<Grid.RowDefinitions>
<RowDefinition MaxHeight="{DynamicResource {x:Static SystemParameters.VerticalScrollBarButtonHeightKey}}"/>
<RowDefinition Height="0.00001*"/>
<RowDefinition MaxHeight="{DynamicResource {x:Static SystemParameters.VerticalScrollBarButtonHeightKey}}"/>
</Grid.RowDefinitions>
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.Row="1" />
<RepeatButton Grid.Row="0" Command="ScrollBar.PageUpCommand" Style="{StaticResource ScrollBarButton}" Content="M 0 4 L 8 4 L 4 0 Z"/>
<Rectangle Grid.Row="1" VerticalAlignment="Top" x:Name="ThumbReplacer" Fill="{DynamicResource ScrollColor}"/>
<RepeatButton Grid.Row="2" Command="ScrollBar.PageDownCommand" Style="{StaticResource ScrollBarButton}" Content="M 0 0 L 4 4 L 8 0 Z"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
