Dev控件类似于ComBox的DropDownControl用法

　　dropDownButton1.DropDownControl= CreateDXPopupMenu();

private DXPopupMenu CreateDXPopupMenu()

{

DXPopupMenu menu = new DXPopupMenu();

menu.Items.Add(new DXMenuItem("Item", OnItemClick));

menu.Items.Add(new DXMenuCheckItem("CheckItem", false, null, OnItemClick));

DXSubMenuItem subMenu = new DXSubMenuItem("SubMenu");

subMenu.Items.Add(new DXMenuItem("SubItem", OnItemClick));

menu.Items.Add(subMenu);

return menu;

}

private void OnItemClick(object sender, EventArgs e)

{

DXMenuItem item = sender as DXMenuItem;

XtraMessageBox.Show(UserLookAndFeel.Default, "OK");

}
