RowDefinition::Height Property

.NET Framework 4.5

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets the calculated height of a RowDefinition element, or sets the GridLength value of a row that is defined by the RowDefinition.

Namespace: System.Windows.Controls
Assembly: PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

Syntax

C++

public:
property GridLength Height {
	GridLength get ();
	void set (GridLength value);
}

XAML Attribute Usage

<object Height="GridLength" .../>

Property Value

Type: System.Windows::GridLength
The GridLength that represents the height of the row. The default value is 1.0.

Dependency Property Information

Identifier field	HeightProperty
Metadata properties set to true	None

Remarks

The default GridUnitType is Star.

When you use these values in the same code example, the MinHeight value takes precedence over the MaxHeight value, which in turn takes precedence over the Height value.

When you add or remove rows or columns, the ActualWidth for all ColumnDefinition elements and the ActualHeight of all RowDefinition elements becomes zero until Measure is called.

Examples

The following example shows how to create and use an instance of GridLengthConverter. The example defines a custom method called changeCol, which passes the ListBoxItem to a GridLengthConverter that converts the Content of a ListBoxItem to an instance of GridLength. The converted value is then passed back as the value of the Width property of the ColumnDefinition element.

The example also defines a second custom method, called changeColVal. This custom method converts the Value of a Slider to a String and then passes that value back to the ColumnDefinition as the Width of the element.

Note that a separate Extensible Application Markup Language (XAML) file defines the contents of a ListBoxItem.

C++

No code example is currently available or this language may not be supported.
