Exemples

L’exemple de code suivant utilise la propriété d’un DataGridViewColumn pour ajouter des fonctionnalités pour modifier la ContextMenuStrip couleur d’arrière-plan d’une cellule. Cet exemple de code fait partie d’un exemple plus grand fourni pour la DataGridViewColumn classe.

ToolStripMenuItem^ toolStripItem1;
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

Remarques

Le menu contextuel s’affiche lorsqu’un utilisateur clique sur le bouton droit de la souris dans la zone d’affichage de la bande. La zone d’affichage est une DataGridViewColumn ou DataGridViewRow dans un DataGridView.
