How to scroll the enitre Windows Phone page with webbrowser content? - c#

I have a webbrowser in my page, with other controls, I simply just want to scroll the entire page, instead of only scrolling the webbrowser. how can I do this?
my code:
<ScrollViewer >
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="White">
<Grid.Resources>
<convertstring:htmlconverter x:Name="htmlconv"/>
<convertstring:DateTimeToStringConverter x:Name="datetimestringconverter"/>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="200"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="/Images/smallerheading.png"
Margin="0,0,10,0"
Grid.Column="1"/>
<TextBlock Text="Stuff"
Foreground="Black"
FontSize="45"
Margin="15,5,0,0"
/>
<Image Grid.Row="1" Grid.ColumnSpan="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
x:Name="img"/>
<TextBlock Grid.Row="2"
x:Name="txtTitle"
TextWrapping="Wrap"
Grid.ColumnSpan="2"
FontSize="30"
Foreground="Black" />
<StackPanel Grid.Row="3">
<TextBlock Grid.Column="0"
x:Name="Autho"
TextWrapping="Wrap"
Foreground="Black"/>
<TextBlock
Foreground="Black"
x:Name="txtDate"/>
</StackPanel>
<phone:WebBrowser x:Name="webbrowsercontrol"
Grid.Row="4"
Background="Transparent"
Foreground="Black"
Grid.ColumnSpan="2"
FontSize="20">
</phone:WebBrowser>
</Grid>
</ScrollViewer>

If you don't want to scroll the WebBrowser at all, you can draw a Border that is almost transparent (like #01000000).
That way, your touch movements will not be handled by the WebBrowser, but by the Border and the page will scroll instead of the WebBrowser content.

UWP: Cannot make ListView scrollable

I have a page with a simple grid (2x2). In one grid on the bottom left corner is another Grid and inside this grid is a ListView bound to a collection. Entries can be added to the collection so the ListView grows in height (height of ListView is set to auto, so that all space available is used).
What I want is, if all available space (from the screen height) is used, scrollbars for the ListView should appear and should be usable. Funny (unfunny) thing is: scrollbars do appear but I cannot use them, I cannot scroll the ListView with the vertical scrollbar that appears when I hover the ListView.
It works, when I set the height of the ListView to a fixed value, but I don't want it that way, because then it doesn't use all the available space on the screen.
This is the XAML of the page (I removed some parts for demonstration purposes) :
<Page

Can someone spot why it is behaving this way?
You need to set the height of the second row to "*" for both grids.

change scrollbar inside scrollviewer

there is a grid inside scrollviewer which is having a vertical scrollbar. But that scroll bar is not clear, there are 2 small horizontal lines at the bottom of scrollbar.
<ScrollViewer VerticalScrollBarVisibility="Auto" >
<Grid VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button Name="DetailsBackButton" Style="{StaticResource BackButtonStyle}" Click="AttachementDetailsBackButton_Click" Grid.Row="0" Visibility="Collapsed" />
<Grid Grid.Row="1">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<ListBox x:Name="DetailsListbox" BorderBrush="#d2d4d5" BorderThickness="1" FontFamily="Arial" FontSize="12px" ItemsSource="{Binding}" Grid.Row="0" Visibility="Collapsed" Width="{Binding RelativeSource={RelativeSource TemplatedParent},Path=ActualHeight}" Style="{DynamicResource ListBoxDefaultStyle}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid >
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Text="{Binding Title}" Grid.Row="0" Style="{DynamicResource AttachmentTitleText}" MouseLeftButtonDown="AttachmentTitle_MouseLeftButtonDown" >
</TextBlock>
<Border Style="{DynamicResource AreaButtonBorder}" Grid.Row="1"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ListBox>
<WebBrowser Name="WebBrowser" Style="{DynamicResource WebBrowserStyle}" Visibility="Visible" Grid.Row="1" Navigating="FullTextWebBrowser_Navigating" LoadCompleted="WebBrowser_LoadCompleted" />
</Grid>
</Grid>
</ScrollViewer>
And further, if I am scrolling it a bit, these 2 horizontal lines will go off. how this can be solved? or Is there any way to move the scroll bar little down by default inside scrollviewer?
Thanks.

Content of ScrollViewer won't extend

I have the following Window
Now if I try to pull down the Gridsplitter I can only as far as the blue Grid fits in the visible Window. But when sliding down the splitter I want a scrollbar to appear and be able to pull it down to the botton until the blue Grid is not visible any more.
<Window.Content>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="25"/>
<RowDefinition />
<RowDefinition Height="25" />
</Grid.RowDefinitions>
<Menu Name="MainMenu" Grid.Row="0">
</Menu>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<DockPanel x:Name="Green" Grid.Column="0" Width="Auto" Height="Auto">
<views:MyView></views:MyView>
</DockPanel>
<GridSplitter Grid.Column="0" Width="6"></GridSplitter>
<Grid Grid.Column="1" >
<ScrollViewer VerticalScrollBarVisibility="Auto">
<Grid VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="7" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<views:ListView x:Name="Yellow" ></views:ListView>
</Grid>
<GridSplitter Grid.Row="1" Height="7" HorizontalAlignment="Stretch" />
<Grid Grid.Row="2" >
<ContentControl Content="{Binding LoadedControl}" x:Name="Blue" />
</Grid>
</Grid>
</ScrollViewer>
</Grid>
</Grid>
<StatusBar x:Name="StatusBar" Grid.Row="2">
</StatusBar>
</Grid>
</Window.Content>
What do I have to change here?
Move your ScrollViewer further down so it wraps the blue ContentControl in row 2, and ensure the ContentControl has a Height or MinHeight set.
ScrollViewers allow their child to take up as much space as they want, and only shows scrollbars if the child object gets larger than the ScrollViewer size.
Also as a side note, you can remove some of those extra Grid's in your layout to make it easier to read. Here's an example with a bunch of them removed, and the first one being replaced with a DockPanel :)
<DockPanel>
<Menu Name="MainMenu" DockPanel.Dock="Top" Height="25" />
<StatusBar x:Name="StatusBar" DockPanel.Dock="Bottom" Height="25"/>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="6" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<views:MyView x:Name="Green" Grid.Column="0" />
<GridSplitter Grid.Column="1" Width="6" />
<Grid Grid.Column="2" >
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="7" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<views:ListView x:Name="Yellow" Grid.Row="0" />
<GridSplitter Grid.Row="1" Height="7" HorizontalAlignment="Stretch" />
<ScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Auto">
<ContentControl x:Name="Blue" MinHeight="400"/>
</ScrollViewer>
</Grid>
</Grid>
</DockPanel>
Hope you find a better solution XD as mine use a code behind
I used the DragDelta event of the control GridSplitter and enlarge the height of the grid so the ScrollBar can be activated
The xaml Code:
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<DockPanel x:Name="Green" Grid.Column="0" Width="Auto" Height="Auto" Background="#FF0CFA8F" >
<local:BusyUserControl Width="200" Height="200"/>
</DockPanel>
<GridSplitter ResizeDirection="Rows" Grid.Column="0" Width="6"></GridSplitter>
<ScrollViewer x:Name="MainScrollViewer" VerticalScrollBarVisibility="Auto" Grid.Column="1" >
<Grid x:Name="MainGrid">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="7" />
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid >
<views:ListView x:Name="Yellow" ></views:ListView>
</Grid>
<GridSplitter Grid.Row="1" Height="7" ResizeBehavior="PreviousAndNext" HorizontalAlignment="Stretch" DragDelta="GridSplitter_DragDelta" />
<Grid Grid.Row="2">
<ContentControl Content="{Binding LoadedControl}" x:Name="Blue" />
</Grid>
</Grid>
</ScrollViewer>
</Grid>
The code Behind:
private void GridSplitter_DragDelta(object sender, System.Windows.Controls.Primitives.DragDeltaEventArgs e)
{
if (e.VerticalChange > 1500 || e.VerticalChange > -15000) return;
if (e.VerticalChange > 0 || Visibility.Visible.Equals(MainScrollViewer.ComputedVerticalScrollBarVisibility))
{
this.MainGrid.Height = this.MainGrid.ActualHeight + e.VerticalChange;
}
e.Handled = true;
}
Note:
When the scrollbar is no more visible I stop shrinking the grid (keep the grid stretshed) that’s the meaning of the condition
Visibility.Visible.Equals(MainScrollViewer.ComputedVerticalScrollBarVisibility)
Hope this could help you and thx for the question :)
if you want to display a vertical scroll bar for each part in the splitted grid try the following code :
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<DockPanel x:Name="Green" Grid.Column="0" Width="Auto" Height="Auto" Background="#FF0CFA8F" >
<local:BusyUserControl Width="200" Height="200"/>
</DockPanel>
<GridSplitter Grid.Column="0" Width="6"></GridSplitter>
<Grid Grid.Column="1" >
<Grid VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="7" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="0" >
<Grid >
<views:ListView x:Name="Yellow" ></views:ListView>
</Grid>
</ScrollViewer>
<GridSplitter Grid.Row="1" Height="7" HorizontalAlignment="Stretch" />
<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="2" >
<Grid Grid.Row="2" >
<ContentControl Content="{Binding LoadedControl}" x:Name="Blue" />
</Grid>
</ScrollViewer>
</Grid>
</Grid>
</Grid>
otherwise clarify your need

Avoid inheritance of opacity between nested Grids

I have a Grid with its background as black an opacity to 0.5 and in it is there another grid with opacity to 1 and background as White. But the inner grid still shows as its opacity was 0.5
<Grid Grid.ColumnSpan="2" Grid.RowSpan="2" Background="Black" Opacity="0.5" Visibility="{Binding Alertar, Converter={cnv:boolToVisibilityConverter}}">
<Grid.RowDefinitions>
<RowDefinition Height="2*"></RowDefinition>
<RowDefinition Height="5*"></RowDefinition>
<RowDefinition Height="2*"></RowDefinition>
</Grid.RowDefinitions>
<Grid Grid.Row="1" Background="Black" Opacity="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="7*"/>
<ColumnDefinition Width="3*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="10*"/>
<RowDefinition Height="1.5*"/>
</Grid.RowDefinitions>
<Rectangle Grid.ColumnSpan="3" Grid.RowSpan="2" Fill="Black" Opacity="1"/>
<TextBlock Grid.Column="1" Margin="0,15,0,0" Text="{Binding ReporteInconsistencias}" />
<Button Grid.Column="1" Grid.Row="1" Content="Aceptar" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10"/>
</Grid>
</Grid>
I'm trying to emulate a win8 alert screen there is another way to do this? or How to prevent this inheritance? why this happen?
A little messy but this should work i think. Basically controls are stacked. So having the grid come after the first grid it shouldn't effect the opacity. May need to be tweaked, but something along the lines of this should work:
<Grid Grid.ColumnSpan="2" Grid.RowSpan="2" Visibility="{Binding Alertar, Converter={cnv:boolToVisibilityConverter}}">
<Grid.RowDefinitions>
<RowDefinition Height="2*"></RowDefinition>
<RowDefinition Height="5*"></RowDefinition>
<RowDefinition Height="2*"></RowDefinition>
</Grid.RowDefinitions>
<Grid Grid.RowSpan="3" Background="Black" Opacity="0.5" />
<Grid Grid.Row="1" Background="Black" Opacity="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="7*"/>
<ColumnDefinition Width="3*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="10*"/>
<RowDefinition Height="1.5*"/>
</Grid.RowDefinitions>
<Rectangle Grid.ColumnSpan="3" Grid.RowSpan="2" Fill="Black" Opacity="1"/>
<TextBlock Grid.Column="1" Margin="0,15,0,0" Text="{Binding ReporteInconsistencias}" />
<Button Grid.Column="1" Grid.Row="1" Content="Aceptar" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10"/>
</Grid>
</Grid>

Grid in ScrollViewer doesn't scroll horizontally

I think I'm missing something simple here... how do I get a Grid inside a ScrollViewer to scroll horizontally? I've enabled HorizontalScrollMode, and the content is definitely long enough that it runs off the screen, but it doesn't scroll. Here's the offending code (this ScrollViewer is the lone content of a row of the LayoutRoot Grid):
<ScrollViewer Grid.Row="1" VerticalScrollMode="Disabled"
VerticalScrollBarVisibility="Hidden"
HorizontalScrollMode="Enabled">
<Grid Margin="120,0,0,100">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="240"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="240"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="240"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="240"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Text="Download" HorizontalAlignment="Center" Margin="0,0,0,10"/>
<local:BandwidthMeter Grid.Row="1" x:Name="PolicyDown" Grid.Column="0"/>
<TextBlock Grid.Column="2" Text="Upload" HorizontalAlignment="Center"/>
<local:BandwidthMeter Grid.Row="1" x:Name="PolicyUp" Grid.Column="2"/>
<TextBlock Grid.Column="4" Text="Download" HorizontalAlignment="Center"/>
<local:BandwidthMeter x:Name="ActualDown" Grid.Row="1" Grid.Column="4"/>
<TextBlock Grid.Column="6" Text="Upload" HorizontalAlignment="Center"/>
<local:BandwidthMeter x:Name="ActualUp" Grid.Row="1" Grid.Column="6" />
<TextBlock Grid.Column="7" Text="Campus-wide bandwidth usage" HorizontalAlignment="Center"/>
<Image Grid.Column="7" Grid.Row="1" Margin="80,0,0,0" Source="[image URL]" Stretch="UniformToFill"/>
</Grid>
</ScrollViewer>
Add the property HorizontalScrollBarVisibility="Auto" to your ScrollViewer.
