Esempio

Nell'esempio di codice seguente viene illustrato come creare e inizializzare ToolStripDropDownItem i controlli. Questo esempio di codice fa parte di un esempio più grande fornito per la ToolStripDropDownItem classe.

// This utility method creates and initializes three 
// ToolStripDropDownItem controls and adds them 
// to the form's ToolStrip control.
private void InitializeToolStripDropDownItems()
{
    ToolStripDropDownButton b = new ToolStripDropDownButton("DropDownButton");
    b.DropDown = this.contextMenuStrip1;
    b.DropDownClosed += new EventHandler(toolStripDropDownItem_DropDownClosed);
    b.DropDownItemClicked += new ToolStripItemClickedEventHandler(toolStripDropDownItem_DropDownItemClicked);
    b.DropDownOpened += new EventHandler(toolStripDropDownItem_DropDownOpened);

    ToolStripMenuItem m = new ToolStripMenuItem("MenuItem");
    m.DropDown = this.contextMenuStrip1;
    m.DropDownClosed += new EventHandler(toolStripDropDownItem_DropDownClosed);
    m.DropDownItemClicked += new ToolStripItemClickedEventHandler(toolStripDropDownItem_DropDownItemClicked);
    m.DropDownOpened += new EventHandler(toolStripDropDownItem_DropDownOpened);

    ToolStripSplitButton sb = new ToolStripSplitButton("SplitButton");
    sb.DropDown = this.contextMenuStrip1;
    sb.DropDownClosed += new EventHandler(toolStripDropDownItem_DropDownClosed);
    sb.DropDownItemClicked += new ToolStripItemClickedEventHandler(toolStripDropDownItem_DropDownItemClicked);
    sb.DropDownOpened += new EventHandler(toolStripDropDownItem_DropDownOpened);

    this.toolStrip1.Items.AddRange(new ToolStripItem[] { b, m, sb });
}

' This utility method creates and initializes three 
' ToolStripDropDownItem controls and adds them 
' to the form's ToolStrip control.
Private Sub InitializeToolStripDropDownItems()
   Dim b As New ToolStripDropDownButton("DropDownButton")
   b.DropDown = Me.contextMenuStrip1
   AddHandler b.DropDownClosed, AddressOf toolStripDropDownItem_DropDownClosed
   AddHandler b.DropDownItemClicked, AddressOf toolStripDropDownItem_DropDownItemClicked
   AddHandler b.DropDownOpened, AddressOf toolStripDropDownItem_DropDownOpened
   
   Dim m As New ToolStripMenuItem("MenuItem")
   m.DropDown = Me.contextMenuStrip1
   AddHandler m.DropDownClosed, AddressOf toolStripDropDownItem_DropDownClosed
   AddHandler m.DropDownItemClicked, AddressOf toolStripDropDownItem_DropDownItemClicked
   AddHandler m.DropDownOpened, AddressOf toolStripDropDownItem_DropDownOpened
   
   Dim sb As New ToolStripSplitButton("SplitButton")
   sb.DropDown = Me.contextMenuStrip1
   AddHandler sb.DropDownClosed, AddressOf toolStripDropDownItem_DropDownClosed
   AddHandler sb.DropDownItemClicked, AddressOf toolStripDropDownItem_DropDownItemClicked
   AddHandler sb.DropDownOpened, AddressOf toolStripDropDownItem_DropDownOpened
   
   Me.toolStrip1.Items.AddRange(New ToolStripItem() {b, m, sb})

Commenti

È necessario derivare un controllo a discesa dalla ToolStripDropDownItem classe per avere qualsiasi funzionalità a discesa per un ToolStripDropDownButtoncontrollo , ToolStripMenuItemo ToolStripSplitButton .

protected:
 ToolStripDropDownItem(System::String ^ text, System::Drawing::Image ^ image, EventHandler ^ onClick);

protected ToolStripDropDownItem (string text, System.Drawing.Image image, EventHandler onClick);

new System.Windows.Forms.ToolStripDropDownItem : string * System.Drawing.Image * EventHandler -> System.Windows.Forms.ToolStripDropDownItem

Protected Sub New (text As String, image As Image, onClick As EventHandler)
