Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Steuerelemente erstellt und initialisiert ToolStripDropDownItem werden. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die ToolStripDropDownItem Klasse bereitgestellt wird.

// 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 });
}
