방법: ColumnDefinitionsCollections 및 RowDefinitionsCollections를 사용하여 열 및 행 조작
업데이트: 2007년 11월
이 예제에서는 ColumnDefinitionCollection 및 RowDefinitionCollection 클래스의 메서드를 사용하여 행이나 열의 내용 추가, 지우기 또는 계산과 같은 작업을 수행하는 방법을 보여 줍니다. 예를 들어 ColumnDefinition 또는 RowDefinition에 포함된 항목에 대해 Add, Clear 또는 Count를 수행할 수 있습니다. 전체 샘플을 보려면 행 및 열 컬렉션 샘플을 참조하십시오.
예제
다음 예제에서는 Name이 grid1인 Grid 요소를 만듭니다. Grid에는 각각 서로 다른 컬렉션 메서드로 제어되는 Button 요소가 저장되는 StackPanel이 포함됩니다. Button을 클릭하면 코드 숨김 파일에서 메서드 호출이 활성화됩니다.
<Grid DockPanel.Dock="Top" HorizontalAlignment="Left" Name="grid1" ShowGridLines="true" Width="625" Height="400" Background="#b0e0e6">

<StackPanel HorizontalAlignment="Left" Orientation="Horizontal" Width="625" DockPanel.Dock="Top">

<Button Width="125" Click="clearCol">Clear All Columns</Button>
<Button Width="125" Click="clearRow">Clear All Rows</Button>
<Button Width="125" Click="removeCol">Remove One Column</Button>
</StackPanel>
<StackPanel HorizontalAlignment="Left" Orientation="Horizontal" Width="625" DockPanel.Dock="Top">
<Button Width="125" Click="removeRow">Remove One Row</Button>
<Button Width="125" Click="colCount">How Many Columns?</Button>
<Button Width="125" Click="rowCount">How Many Rows?</Button>
<Button Width="125" Click="rem5Col">Remove 5 Columns</Button>
<Button Width="125" Click="rem5Row">Remove 5 Rows</Button>
</StackPanel>
<StackPanel HorizontalAlignment="Left" Orientation="Horizontal" Width="625" DockPanel.Dock="Top">
<Button Width="125" Click="containsRow">Contains Row?</Button>
<Button Width="125" Click="containsCol">Contains Column?</Button>
<Button Width="125" Click="insertRowAt">Insert Row</Button>
<Button Width="125" Click="insertColAt">Insert Column</Button>
<Button Width="125" Click="colReadOnly">IsReadOnly?</Button>
</StackPanel>
이 예제에서는 각각 XAML(Extensible Application Markup Language) 파일의 Click 이벤트에 해당하는 일련의 사용자 지정 메서드를 정의합니다. Grid의 열과 행 수를 여러 방법으로 변경할 수 있습니다. 여기에는 행과 열 추가 또는 제거 및 전체 행과 열 수 계산이 포함됩니다. ArgumentOutOfRangeException 및 ArgumentException 예외가 발생하지 않도록 하려면 RemoveRange 메서드가 제공하는 오류 검사 기능을 사용할 수 있습니다.
