void AddContextMenu()
{
   toolStripItem1->Text = L"Redden";
   toolStripItem1->Click += gcnew EventHandler( this, &DataGridViewColumnDemo::toolStripItem1_Click );
   System::Windows::Forms::ContextMenuStrip^ strip = gcnew System::Windows::Forms::ContextMenuStrip;
   IEnumerator^ myEnum = dataGridView->Columns->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      DataGridViewColumn^ column = safe_cast<DataGridViewColumn^>(myEnum->Current);
      column->ContextMenuStrip = strip;
      column->ContextMenuStrip->Items->Add( toolStripItem1 );
   }
}

DataGridViewCellEventArgs^ mouseLocation;

// Change the cell's color.
void toolStripItem1_Click( Object^ /*sender*/, EventArgs^ /*args*/ )
{
   dataGridView->Rows[ mouseLocation->RowIndex ]->Cells[ mouseLocation->ColumnIndex ]->Style->BackColor = Color::Red;
}


// Deal with hovering over a cell.
void dataGridView_CellMouseEnter( Object^ /*sender*/, DataGridViewCellEventArgs^ location )
{
   mouseLocation = location;
}

ToolStripMenuItem toolStripItem1 = new ToolStripMenuItem();

private void AddContextMenu()
{
    toolStripItem1.Text = "Redden";
    toolStripItem1.Click += new EventHandler(toolStripItem1_Click);
    ContextMenuStrip strip = new ContextMenuStrip();
    foreach (DataGridViewColumn column in dataGridView.Columns)
    {

        column.ContextMenuStrip = strip;
        column.ContextMenuStrip.Items.Add(toolStripItem1);
    }
}

private DataGridViewCellEventArgs mouseLocation;

// Change the cell's color.
private void toolStripItem1_Click(object sender, EventArgs args)
{
    dataGridView.Rows[mouseLocation.RowIndex]
        .Cells[mouseLocation.ColumnIndex].Style.BackColor
        = Color.Red;
}

// Deal with hovering over a cell.
private void dataGridView_CellMouseEnter(object sender,
    DataGridViewCellEventArgs location)
{
    mouseLocation = location;
}

WithEvents toolStripItem1 As New ToolStripMenuItem()

Private Sub AddContextMenu()
    toolStripItem1.Text = "Redden"
    Dim strip As New ContextMenuStrip()
    For Each column As DataGridViewColumn _
        In dataGridView.Columns()

        column.ContextMenuStrip = strip
        column.ContextMenuStrip.Items.Add(toolStripItem1)
    Next
End Sub
' Change the cell's color.
Private Sub toolStripItem1_Click(ByVal sender As Object, _
    ByVal args As EventArgs) _
    Handles toolStripItem1.Click

    dataGridView.Rows(mouseLocation.RowIndex) _
        .Cells(mouseLocation.ColumnIndex) _
        .Style.BackColor = Color.Red
End Sub

Private mouseLocation As DataGridViewCellEventArgs

' Deal with hovering over a cell.
Private Sub dataGridView_CellMouseEnter(ByVal sender As Object, _
    ByVal location As DataGridViewCellEventArgs) _
    Handles DataGridView.CellMouseEnter

    mouseLocation = location
End Sub
