C＃ - 获取ToolStripMenuItem的父级

Question

如何确定ToolStripMenuItem的父级？使用普通的MenuStrip，您只需使用Parent属性，但ToolStripMenuItem似乎没有该属性。我有一个ToolStripDropDownButton，它有几个ToolStripMenuItems，我希望能够以编程方式精确定位那些父类。

Answer 1

尝试OwnerItem属性。

Answer 2

这对我有用：

ToolStripMenuItem menuItem = sender as ToolStripMenuItem;

ToolStrip toolStrip = menuItem.GetCurrentParent();

...从这里开始，您可以设计一种方法，将您从随机ToolStripMenuItem带到最高级别：

public static class ToolStripItemExtension
{
    public static ContextMenuStrip GetContextMenuStrip(this ToolStripItem item)
    {
        ToolStripItem itemCheck = item;            

        while (!(itemCheck.GetCurrentParent() is ContextMenuStrip) && itemCheck.GetCurrentParent() is ToolStripDropDown)
        {
            itemCheck = (itemCheck.GetCurrentParent() as ToolStripDropDown).OwnerItem;
        }

        return itemCheck.GetCurrentParent() as ContextMenuStrip;
    }
}

Answer 3

试试这个......

ToolStripMenuItem t = (ToolStripMenuItem)sender;
ContextMenuStrip s = (ContextMenuStrip)t.Owner;
MessageBox.Show(s.SourceControl.Name);

Answer 4

这就是你要找的东西

private void ContextMenuStrip_Opening(object sender, CancelEventArgs e)
{
    contextMenuStrip1.Tag = ((ContextMenuStrip)sender).OwnerItem;
}
private void ToolStripMenuItem_Click(object sender, EventArgs e)
{
    ToolStripMenuItem senderItem = (ToolStripMenuItem)sender;
    var ownerItem = (ToolStripMenuItem)((ContextMenuStrip)senderItem.Owner).Tag;
}

Answer 5

在搜索了许多关于该问题的帖子后，我发现这对我有用：

ToolStripMenuItem mi = (ToolStripMenuItem)sender;
ToolStripMenuItem miOwnerItem = (ToolStripMenuItem)(mi.GetCurrentParent() as ToolStripDropDown).OwnerItem;
