如何使用动态添加的toolstripmenuitem

Question

我试图制作一个包含书签的工具条项目，每个书签都应该转到该页面。如何使每个按钮工作？。

    For Each b In New System.IO.DirectoryInfo("Bookmarks").GetFiles
        BookmarksToolStripMenuItem.DropDownItems.Add(b.Name)
    Next

Answer 1

您应首先创建一个ToolStripMenuItem，然后添加处理程序并将其放到您的toolstripmenu对象中，而不是添加到toolstripmenu一个字符串对象。

For Each b In New System.IO.DirectoryInfo("Bookmarks").GetFiles
    Dim menuItem As New ToolStripMenuItem(b.Name)
    'Add any handlers here

    'Click handler to your menuItem.
    AddHandler menuItem.Click, AddressOf menuItem_Click 'CLICK EVENT HANDLER ALSO UNIQUE

    'Add menuItem to ToolStripMenu
    BookmarksToolStripMenuItem.DropDownItems.Add(menuItem)
Next


Private Sub menuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
    'CODE TO HANDLE CLICK EVENT
End Sub
