示例

下面的代码示例演示了此类型的用法。 此示例是 “操作方法：使用 Windows 窗体 DataGridView 控件中的图像列”中提供的大型示例的一部分。

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
