上下文菜单父级？

Question

嗨我在标签上添加了一个上下文菜单(c#,winforms).我的上下文菜单有3个子项,我想在我点击任何一个上下文菜单项时显示标签文本.

提前致谢

该ContextMenuStrip控件具有一个SourceControl属性,该属性将引用打开它的控件.您可以使用它从控件中提取文本:

private void MenuStripItem_Click(object sender, EventArgs e)
{
    ToolStripItem item = (sender as ToolStripItem);
    if (item != null)
    {
        ContextMenuStrip owner = item.Owner as ContextMenuStrip;
        if (owner != null)
        {
            MessageBox.Show(owner.SourceControl.Text);
        }
    }
}

如果您不ContextMenuStrip使用a ContextMenu,代码应如下所示:

private void menuItem1_Click(object sender, EventArgs e)
{
    MenuItem item = (sender as MenuItem);
    if (item != null)
    {
        ContextMenu owner = item.Parent as ContextMenu;
        if (owner != null)
        {
            MessageBox.Show(owner.SourceControl.Text);
        }
    }
}

这是一行中最好的：

Control control = ((ContextMenuStrip)((ToolStripItem)sender).Owner).SourceControl;
