Bottom borders on WPF Grid

I'd like to set a bottom border on each row in the grid, but can only find how to put all 4 borders around each cell..

<Grid Height="174" HorizontalAlignment="Left" Margin="23,289,0,0" Name="grid2" VerticalAlignment="Top" Width="730">
    <Grid.RowDefinitions>
        <RowDefinition Height="45" />
        <RowDefinition Height="25" />
        <RowDefinition Height="25" />
        <RowDefinition Height="25" />
        <RowDefinition Height="25" />
        <RowDefinition Height="25" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="255" />
        <ColumnDefinition Width="95" />
        <ColumnDefinition Width="95" />
        <ColumnDefinition Width="95" />
        <ColumnDefinition Width="95" />
        <ColumnDefinition Width="95" />
    </Grid.ColumnDefinitions>
</Grid>

For another grid I'm using that needs all four borders, I'm using

<Border Grid.Column="0" Grid.Row="0" BorderBrush="#61738B" BorderThickness="1" />

P.S. The contents of the grid are some labels, textboxes, etc.. if that matters at all.

Solution 1:

On a Border control You can do BorderThickness="0 0 0 1" to only have a bottom border shown.

Top and bottom border thickness of 5, left and right border thickness of 0

BorderThickness="0 5"

Top and bottom border thickness of 0, left and right border thickness of 5

BorderThickness="5 0"

Border Thickness - Left: 1, Top: 2, Right:3, Bottom: 4

BorderThickness="1 2 3 4"

Hope this helps!
