Methods

The Grid class has these methods. It also inherits methods from the Object class.

MethodDescription
AddHandler Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked even if the event is handled elsewhere. (Inherited from UIElement)
Arrange Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. (Inherited from UIElement)
ArrangeOverride Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior. (Inherited from FrameworkElement)
CancelDirectManipulations Cancels ongoing direct manipulation processing (system-defined panning/zooming) on any ScrollViewer parent that contains the current UIElement. (Inherited from UIElement)
CapturePointer Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events. (Inherited from UIElement)
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject)
FindName Retrieves an object that has the specified identifier name. (Inherited from FrameworkElement)
FindSubElementsForTouchTargeting Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. (Inherited from UIElement)
GetAnimationBaseValue Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetBindingExpression Returns the BindingExpression that represents the binding on the specified property. (Inherited from FrameworkElement)
GetColumn Gets the value of the Grid.Column XAML attached property from the specified FrameworkElement.
GetColumnSpan Gets the value of the Grid.ColumnSpan XAML attached property from the specified FrameworkElement.
GetRow Gets the value of the Grid.Row XAML attached property from the specified FrameworkElement.
GetRowSpan Gets the value of the Grid.RowSpan XAML attached property from the specified FrameworkElement.
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
GoToElementStateCore When implemented in a derived class, enables per-state construction of a visual tree for a control template in code, rather than by loading XAML for all states at control startup. (Inherited from FrameworkElement)
InvalidateArrange Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. (Inherited from UIElement)
InvalidateMeasure Invalidates the measurement state (layout) for a UIElement. (Inherited from UIElement)
Measure Updates the DesiredSize of a UIElement. Typically, objects that implement custom layout for their layout children call this method from their own MeasureOverride implementations to form a recursive layout update. (Inherited from UIElement)
MeasureOverride Provides the behavior for the Measure pass of the layout cycle. Classes can override this method to define their own Measure pass behavior. (Inherited from FrameworkElement)
OnApplyTemplate Invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class. (Inherited from FrameworkElement)
OnCreateAutomationPeer When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure. (Inherited from UIElement)
OnDisconnectVisualChildren Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property. (Inherited from UIElement)
ReadLocalValue Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
ReleasePointerCapture Releases pointer captures for capture of one specific pointer by this UIElement. (Inherited from UIElement)
ReleasePointerCaptures Releases all pointer captures held by this element. (Inherited from UIElement)
RemoveHandler Removes the specified routed event handler from this UIElement. Typically the handler in question was added by AddHandler. (Inherited from UIElement)
SetBinding Attaches a binding to a FrameworkElement, using the provided binding object. (Inherited from FrameworkElement)
SetColumn Sets the value of the Grid.Column XAML attached property on the specified FrameworkElement.
SetColumnSpan Sets the value of the Grid.ColumnSpan XAML attached property on the specified FrameworkElement.
SetRow Sets the value of the Grid.Row XAML attached property on the specified FrameworkElement.
SetRowSpan Sets the value of the Grid.RowSpan XAML attached property on the specified FrameworkElement.
SetValue Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
TransformToVisual Returns a transform object that can be used to transform coordinates from the UIElement to the specified object. (Inherited from UIElement)
UpdateLayout Ensures that all positions of child objects of a UIElement are properly updated for layout. (Inherited from UIElement)

Remarks

Grid is a layout panel that supports arranging child elements in rows and columns.

Grid layout panel

You typically define layout behavior for a Grid in XAML by providing one or more RowDefinition elements as the value of Grid.RowDefinitions, and one or more ColumnDefinition elements as the value of Grid.ColumnDefinitions. Then, you apply the Grid.Row and Grid.Column attached properties to each of the element children of the Grid, to indicate which row/column combination is used to position that element within the parent Grid.

To set the height of rows and the width of columns, you set RowDefinition.Height for each RowDefinition and ColumnDefinition.Width for each ColumnDefinition. By default, each row or column divides layout space equally. You can change this behavior either by providing absolute pixel values, or a Star sizing that divides available space using a weighted factor. For more info on how to use Star sizing in a Grid, see Quickstart: Defining layouts or GridLength. You also can use an Auto sizing that sizes to content.

To indicate that an element child should span multiple rows or multiple columns in the Grid, you can apply the Grid.RowSpan or Grid.ColumnSpan attached properties to child elements of a Grid.

By default, a Grid contains one row and one column.

Setting the Margin property on the child elements in a Grid sets the distance between the element and its grid cell boundaries. The HorizontalAlignment and VerticalAlignment properties describe how the child element should be positioned within the grid cell. You can precisely position child elements of a Grid by using a combination of the Margin property and alignment properties. If you need even more control over the layout of individual child elements, consider using VariableSizedWrapGrid.

WrapGrid is another similar layout panel that has the benefit of better handling for content that's too wide, which might be clipped by a regular Grid depending on values of other layout properties.

Grid XAML attached properties

Grid is the host service class for several XAML attached properties. These attached properties enable child elements to report how they should be positioned in their Grid parent.

Grid provides these attached properties for XAML usage:

In order to support XAML processor access to the attached properties, and also to expose equivalent get and set operations to code, each XAML attached property has a pair of Get and Set accessor methods. For example, the GetColumnSpan and SetColumnSpan methods support and provide the equivalent code-only support for Grid.ColumnSpan. Alternatively, you can use the dependency property system to get or set the value of the attached property. Call GetValue or SetValue, passing the arguments of the dependency property identifier to set, and a reference to the target object on which to get or set the value.

Grid derived classes

Grid is the parent class for SwapChainPanel and SwapChainBackgroundPanel.

Examples

This XAML example shows how to design a layout by using a Grid.


<Grid x:Name="LayoutRoot" Background="#555555" Width="400" Height="300">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="250" />
        <ColumnDefinition Width="150" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="2*" />
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" 
               Margin="10" FontWeight="Bold" 
               Text="Contoso Corporation" HorizontalAlignment="Center" VerticalAlignment="Center" />
    <Grid x:Name="FormLayoutGrid" Grid.Row="1" Grid.Column="0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <TextBlock Grid.Row="0" Grid.Column="0" Text="First Name" Margin="10" 
                   HorizontalAlignment="Left" VerticalAlignment="Center" />
        <TextBox Grid.Row="0" Grid.Column="1" Margin="10" />
        <TextBlock Grid.Row="1" Grid.Column="0" Text="Last Name" Margin="10" 
                   HorizontalAlignment="Left" VerticalAlignment="Center" />
        <TextBox Grid.Row="1" Grid.Column="1" Margin="10" />
        <TextBlock Grid.Row="2" Grid.Column="0" Text="Address" Margin="10" 
                   HorizontalAlignment="Left" VerticalAlignment="Center" />
        <TextBox Grid.Row="2" Grid.Column="1" Margin="10" />
      
    </Grid>
 </Grid>


This example builds a UI layout in code rather than using XAML. It illustrates how you might set the various Grid attached properties in code, after you've hooked up all the parent-child relationships in the visual tree for the app.

    }

    private void LayoutDesign()

        StackPanel DeptStackPanel = new StackPanel();
        DeptStackPanel.Margin = new Thickness(10);

        LayoutRoot.Children.Add(DeptStackPanel);
        Grid.SetColumn(DeptStackPanel, 1);
        Grid.SetRow(DeptStackPanel, 1);

        Grid.SetColumnSpan(ButtonsStackPanel, 2);

        Button BackButton = new Button();
        BackButton.Content = "Back";
        BackButton.Width = 100;

        Button CancelButton = new Button();
        CancelButton.Content = "Cancel";
        CancelButton.Width = 100;

        Button NextButton = new Button();
        NextButton.Content = "Next";
        NextButton.Width = 100;

        ButtonsStackPanel.Children.Add(BackButton);
