C# - 獲取 ToolStripMenuItem 的父級

Question

如何確定 ToolStripMenuItem 的父級？ 對於普通的 MenuStrip，您只需使用 Parent 屬性，但 ToolStripMenuItem 似乎沒有該屬性。 我有一個 ToolStripDropDownButton，它有幾個 ToolStripMenuItems，我希望能夠以編程方式查明這些的父級。

Answer 1

試試OwnerItem屬性。

Answer 2

這對我有用：

ToolStripMenuItem menuItem = sender as ToolStripMenuItem;

ToolStrip toolStrip = menuItem.GetCurrentParent();

...由此，您可以設計一種方法將您從隨機 ToolStripMenuItem 帶到最頂層，例如：

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

試試這個……

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

Answer 4

在搜索了很多關於這個問題的帖子后，我發現這對我有用：

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

Answer 5

這是你要找的

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;
}
