Painting outside of the controls

Hello,
I have a MindFusion WPF 2.7 control in a grid layout control, with the scroll bar sitting in a separate grid column of the same control, and everything placed inside of AvalonDock framework. When the control actual width is smaller then the diagram inside, I get an unpleasant effect that the diagram paints the contents outside of the bounds, over the control borders and up to the next control, but under the scrollbar. Any idea how to fix it?

What does your Xaml code look like? I could not reproduce that effect even with ClipToBounds explicitly set to false, the diagram is still clipped by its Grid cell:

Code
Select All
<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:my="http://mindfusion.eu/diagramming/wpf"
    Title="Window1" Width="600" Height="500" >

    <Grid ClipToBounds="False">

		<Grid.ColumnDefinitions>
			<ColumnDefinition Width="300" />
			<ColumnDefinition Width="*" />
		</Grid.ColumnDefinitions>

		<my:Diagram x:Name="diag" ClipToBounds="False" />

	</Grid>

</Window>

ClipToBounds set explicitely to true worked as a solution Wink However, the code was like this:

Code
Select All
 <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="16" />
        </Grid.ColumnDefinitions>

        <Interactivity:Interaction.Triggers>
            ... omitted
        </Interactivity:Interaction.Triggers>

        <ContentControl Grid.Column="0" SizeChanged="ContentControlSizeChanged" Name="DiagramContainer">
            <BoundDiagram:BoundDiagram x:Name="MyBoundDiagram" DataItems="{Binding Path=VisibleElements}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"  AutoResize="None" AutoSnapLinks="False" DynamicLinks="False" RouteLinks="False" Behavior="DoNothing" Background="#FFFFFF" BackBrush="#FFFFFF"  SelectedElement="{Binding Path=SelectedElement, Mode=TwoWay}"/>
        </ContentControl>


        <ScrollBar Name="scrollbar" HorizontalAlignment="Right" Width="16" Grid.Column="1" Value="{Binding Path=CurrentStart, Mode=TwoWay}" Maximum="{Binding Path=TotalSize, Mode=TwoWay}" Minimum="1"  SmallChange="1" LargeChange="10" />
    </Grid>
