Examples

The following example uses three ColumnDefinitions and three RowDefinitions to create a grid that has nine cells, such as in a worksheet. Each cell contains a TextBlock element that represents data, and the top row contains a TextBlock with the ColumnSpan property applied.

XAML


<Grid  VerticalAlignment="Top" HorizontalAlignment="Left"
       Width="350" Height="200">
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>

    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" 
               FontSize="20" FontWeight="Bold" 
               Grid.ColumnSpan="3" Grid.Row="0">Expenses for 2007</TextBlock>
    
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" 
               FontSize="15" FontWeight="Bold" 
               Grid.Row="1" Grid.Column="0">Travel</TextBlock>
    
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center"

               Grid.Row="1" Grid.Column="1">Office Supplies</TextBlock>
    
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center"
               FontSize="15" FontWeight="Bold" 
               Grid.Row="1" Grid.Column="2">Salary</TextBlock>
    
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" 
               Grid.Row="2" Grid.Column="0">20000</TextBlock>
    
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" 
               Grid.Row="2" Grid.Column="1">10000</TextBlock>
    
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" 
               Grid.Row="2" Grid.Column="2">50000</TextBlock>

    <TextBlock FontSize="16" FontWeight="Bold"
