Remove margins in RadPdfViewer

[note prj]

When you import a pdf file as shown in the attached picture, there is a blank space. (The blue part)
I was wondering if there is a setting to remove this margin.

Hello,

This margin is controlled programmatically when changing something in the layout of RadPdfViewer. What you can do to hide the canvas behind the page is to modify the template of the presenter and set transparent colors for the background and remove the borders:

 

<Style TargetType="documentsUI:FixedDocumentPagesPresenter">
    <Setter Property="Background" Value="White" />
    <Setter Property="BorderThickness" Value="0" />
    <Setter Property="Padding" Value="0" />
    <Setter Property="Template">

        <Setter.Value>
            <ControlTemplate TargetType="documentsUI:FixedDocumentPagesPresenter">
                <Grid>
                    <Border Background="Transparent" BorderBrush="Transparent" BorderThickness="0">
                        <ContentPresenter Margin="0" />
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
<Style  TargetType="fixedUI:Page">
    <Setter Property="BorderThickness" Value="0"/>
</Style>

 

The namespaces used in the snippet above refer to the following definitions:

 

xmlns:documentsUI="clr-namespace:Telerik.Windows.Documents.UI;assembly=Telerik.Windows.Controls.FixedDocumentViewers"        
xmlns:fixedUI="clr-namespace:Telerik.Windows.Documents.Fixed.UI;assembly=Telerik.Windows.Controls.FixedDocumentViewers"

 

Please, note that you should use implicit styling if you would like to adopt this approach.

Hope this is helpful.
