如何为bindingNavigator上的按钮指定快捷键？

Question

有没有办法将快捷键分配给BindingNavigator中的标准导航ToolStrip项？

使用.AddStandardItems方法添加的项是ToolStripItem类型,它没有ShortcutKeys属性.

我试图转换为ToolStripMenuItem,但它失败了.

 public void ConfigureMyNavigator()
    {
               // Adds ToolStripItems which don't support shortcut keys           
                m_navigator.AddStandardItems();

                // Adds a ToolStripMenuItem which can support a shortcut key
                var button = new ToolStripMenuItem
                {
                    Size = new Size(0, 0),
                    Text = "Save",
                    ShortcutKeys = (Keys)Shortcut.CtrlS,
                    ToolTipText = "Press Ctrl+S to save"
                };
                button.Click += tsmi_Click;

                m_navigator.Items.Add(button);

                //   This fails with invalid cast exception
                ((ToolStripMenuItem)m_navigator.Items[1]).ShortcutKeys = (Keys)Shortcut.AltLeftArrow;


    }

我想我可以逐一用toolstripmenuitems替换toolstripitems,但觉得这很尴尬.

您可以侦听键命令,然后单击相应的ToolStripButton.覆盖ProcessCmdKey表单代码中的方法:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    switch (keyData)
    {
        case (Keys.Alt | Keys.Left):
            m_navigator.Items[1].PerformClick();
            break;
        case (Keys.Alt | Keys.Right):
            m_navigator.Items[6].PerformClick();
            break;
    }

    return base.ProcessCmdKey(ref msg, keyData);
}
