DataGridViewImageColumn.ImageLayout プロパティ

定義

この列のセルのイメージのレイアウトを取得または設定します。Gets or sets the image layout in the cells for this column.

public:
 property System::Windows::Forms::DataGridViewImageCellLayout ImageLayout { System::Windows::Forms::DataGridViewImageCellLayout get(); void set(System::Windows::Forms::DataGridViewImageCellLayout value); };
public System.Windows.Forms.DataGridViewImageCellLayout ImageLayout { get; set; }
member this.ImageLayout : System.Windows.Forms.DataGridViewImageCellLayout with get, set
Public Property ImageLayout As DataGridViewImageCellLayout

プロパティ値

セルのレイアウトを指定する DataGridViewImageCellLayoutA DataGridViewImageCellLayout that specifies the cell layout. 既定値は、Normal です。The default is Normal.

例外

CellTemplate プロパティの値が null です。The value of the CellTemplate property is null.

次のコード例では、セルに適合するようにイメージを拡大または縮小する方法を示します。The following code example demonstrates how to stretch and zoom images to fit cells. この例は、 「方法: Windows フォーム DataGridView コントロールのイメージ列を操作する」で使用できる、より大きな例の一部です。This example is part of a larger example available in How to: Work with Image Columns in the Windows Forms DataGridView Control.

void Stretch( Object^ sender, EventArgs^ e )
{
   System::Collections::IEnumerator^ myEnum = dataGridView1->Columns->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      DataGridViewImageColumn^ column = safe_cast<DataGridViewImageColumn^>(myEnum->Current);
      column->ImageLayout = DataGridViewImageCellLayout::Stretch;
      column->Description = L"Stretched";
   }
}

void ZoomToImage( Object^ sender, EventArgs^ e )
{
   System::Collections::IEnumerator^ myEnum1 = dataGridView1->Columns->GetEnumerator();
   while ( myEnum1->MoveNext() )
   {
      DataGridViewImageColumn^ column = safe_cast<DataGridViewImageColumn^>(myEnum1->Current);
      column->ImageLayout = DataGridViewImageCellLayout::Zoom;
      column->Description = L"Zoomed";
   }
}

void NormalImage( Object^ sender, EventArgs^ e )
{
   System::Collections::IEnumerator^ myEnum2 = dataGridView1->Columns->GetEnumerator();
   while ( myEnum2->MoveNext() )
   {
      DataGridViewImageColumn^ column = safe_cast<DataGridViewImageColumn^>(myEnum2->Current);
      column->ImageLayout = DataGridViewImageCellLayout::Normal;
      column->Description = L"Normal";
   }
}


private void Stretch(object sender, EventArgs e)
{
    foreach (DataGridViewImageColumn column in
        dataGridView1.Columns)
    {
        column.ImageLayout = DataGridViewImageCellLayout.Stretch;
        column.Description = "Stretched";
    }
}

private void ZoomToImage(object sender, EventArgs e)
{

    foreach (DataGridViewImageColumn column in
        dataGridView1.Columns)
    {
        column.ImageLayout = DataGridViewImageCellLayout.Zoom;
        column.Description = "Zoomed";
    }
}

private void NormalImage(object sender, EventArgs e)
{

    foreach (DataGridViewImageColumn column in
        dataGridView1.Columns)
    {
        column.ImageLayout = DataGridViewImageCellLayout.Normal;
        column.Description = "Normal";
    }
}
Private Sub Stretch(ByVal sender As Object, _
    ByVal e As EventArgs) Handles Button3.Click

    For Each column As DataGridViewImageColumn _
        In dataGridView1.Columns
        column.ImageLayout = DataGridViewImageCellLayout.Stretch
        column.Description = "Stretched image layout"
    Next
End Sub

Private Sub ZoomToImage(ByVal sender As Object, _
    ByVal e As EventArgs) Handles Button4.Click

    For Each column As DataGridViewImageColumn _
        In dataGridView1.Columns
        column.ImageLayout = DataGridViewImageCellLayout.Zoom
        column.Description = "Zoomed image layout"
    Next
End Sub

Private Sub NormalImage(ByVal sender As Object, _
    ByVal e As EventArgs) Handles Button5.Click

    For Each column As DataGridViewImageColumn _
        In dataGridView1.Columns
        column.ImageLayout = DataGridViewImageCellLayout.Normal
        column.Description = "Normal image layout"
    Next
End Sub

注釈

このプロパティの取得または設定は、CellTemplate プロパティによって返されるオブジェクトの ImageLayout プロパティを取得または設定します。Getting or setting this property gets or sets the ImageLayout property of the object returned by the CellTemplate property. このプロパティを設定すると、列のすべてのセルの ImageLayout プロパティも設定され、列の表示が更新されます。Setting this property also sets the ImageLayout property of every cell in the column and refreshes the column display. 個々のセルに対して指定された値をオーバーライドするには、列の値を設定した後にセルの値を設定します。To override the specified value for individual cells, set the cell values after you set the column value.
