如何执行 My button.Command. 在 My button. Click 事件前打开 My button.Command.
原标题:How can execute MyButton.Command.Open before MyButton.Click event?

按钮可以使用 Command. Open 属性和 Click 事件。 但是 button.Click 事件在 button.command. Open 事件之前执行。 由于我的 button. Comand. > 事件代码和 button.Command. Open 代码相互连接, 我需要 Button.Command. Open 先执行, 然后再执行 Button.Click 事件。 这怎么可能?

谢谢,对不起,因为我的英语。

最佳回答

听起来你需要找到一个在 点击 事件之前点火的事件,例如 PreviewMouseDown 事件, 并称之为“ Open” 事件。
