使用ScrollViewer实现按钮控制滚动

xaml：

  <ScrollViewer Name="scroller">

    <Grid Margin="0,10,0,0" Focusable="False">
      <Grid.RowDefinitions>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
      </Grid.RowDefinitions>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"></ColumnDefinition>
        <ColumnDefinition Width="*" MinWidth="50" MaxWidth="800"></ColumnDefinition>
        <ColumnDefinition Width="Auto"></ColumnDefinition>
      </Grid.ColumnDefinitions>

      <Label Grid.Row="0" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Home:</Label>
      <TextBox Grid.Row="0" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="0" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="1" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Network:</Label>
      <TextBox Grid.Row="1" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="1" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="2" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Web:</Label>
      <TextBox Grid.Row="2" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="2" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="3" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Secondary:</Label>
      <TextBox Grid.Row="3" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="3" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="4" Grid.Column="0" Margin="3"
       VerticalAlignment="Center">Home:</Label>
      <TextBox Grid.Row="4" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="4" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="5" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Network:</Label>
      <TextBox Grid.Row="5" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="5" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="6" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Web:</Label>
      <TextBox Grid.Row="6" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="6" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

      <Label Grid.Row="7" Grid.Column="0" Margin="3"
             VerticalAlignment="Center">Secondary:</Label>
      <TextBox Grid.Row="7" Grid.Column="1" Margin="3"
             Height="Auto"  VerticalAlignment="Center"></TextBox>
      <Button Grid.Row="7" Grid.Column="2" Margin="3" Padding="2">Browse</Button>

    </Grid>
    
  </ScrollViewer>

核心代码：

        private void LineUp(object sender, RoutedEventArgs e)
        {
            scroller.LineUp();
        }
        private void LineDown(object sender, RoutedEventArgs e)
        {
            scroller.LineDown();
        }
        private void PageUp(object sender, RoutedEventArgs e)
        {
            scroller.PageUp();
        }
        private void PageDown(object sender, RoutedEventArgs e)
        {
            scroller.PageDown();
        }    

使用scroller.LineUp();scroller.PageUp();等实现滑动
