I am using a ScrollViewer which is inside a Grid control and its alignment is center to screen . There is a web browser control inside the Scrolllviewer and the height and width vary based on size of web page. If height is too big scrollviewer scroller will appear Rough xaml is like this

<Grid>
 <ScrollViewer HAlign="Center" RAlign="Center">
   <Browser/>
 </ScrollViewer/>
</Grid>

if i place button inside scrollviewer what will happen is if the height of browser is too long , button will also goes down . A sample layout can be look like it

Answer 1

here is how I would use a DockPanel for the same

<Grid>
    <DockPanel LastChildFill="True" HorizontalAlignment="Center" VerticalAlignment="Center" MaxWidth="500">
        <Button Content="Prev page" DockPanel.Dock="Left"/>
        <Button Content="Next page" DockPanel.Dock="Right"/>
        <ScrollViewer>
            <WebBrowser Source="http://www.google.com"/>
        </ScrollViewer>
    </DockPanel>
</Grid>

result

above is just an example to show the use of DockPanel

Using Grid

you can use grid with column definitions to enable the stretch to available space or * width

example

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="1*" />
        <ColumnDefinition Width="4*"
                          MaxWidth="500" />
        <ColumnDefinition Width="1*" />
    </Grid.ColumnDefinitions>
    <Button Content="Prev page"
            DockPanel.Dock="Left" />
    <ScrollViewer Grid.Column="1">
        <WebBrowser Source="http://www.google.com" />
    </ScrollViewer>
    <Button Content="Next page"
            DockPanel.Dock="Right"
            Grid.Column="2" />
</Grid>

above example divides grid into 3 columns with 1:4:1 proportion of width. so this will enable to distribute the available space using the defined proportion. additionally I have set the max width to the browser column as 500 px, this will enable the stretching of buttons after the defined width has reached.
