Examples

The following example uses three ColumnDefinition s and three RowDefinition s 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.

<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" 
               FontSize="15" FontWeight="Bold" 
               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" 
               Grid.ColumnSpan="3" Grid.Row="3">Total Expense: 80000</TextBlock>
</Grid>

Constructors

ColumnDefinition() ColumnDefinition() ColumnDefinition() ColumnDefinition()

Initializes a new instance of the ColumnDefinition class.

Properties

ActualWidth ActualWidth ActualWidth ActualWidth

Gets a value that represents the actual calculated width of a ColumnDefinition.

Dispatcher Dispatcher Dispatcher Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)
MaxWidth MaxWidth MaxWidth MaxWidth

Gets or sets a value that represents the maximum width of a ColumnDefinition.

MaxWidthProperty MaxWidthProperty MaxWidthProperty MaxWidthProperty

Identifies the MaxWidth dependency property.

MinWidth MinWidth MinWidth MinWidth

Gets or sets a value that represents the minimum width of a ColumnDefinition.

MinWidthProperty MinWidthProperty MinWidthProperty MinWidthProperty

Identifies the MinWidth dependency property.

Width Width Width Width

Gets the calculated width of a ColumnDefinition element, or sets the GridLength value of a column that is defined by the ColumnDefinition.

WidthProperty WidthProperty WidthProperty WidthProperty

Identifies the Width dependency property.

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

(Inherited from DependencyObject)
GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback)

Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance.

(Inherited from DependencyObject)
SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object)

Sets the local value of a dependency property on a DependencyObject.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.
