Hi,

I have a Navigation Application and I have a custom Control which is going to be on every page.

On this User Control I will have a button which will turn the grid by 180d, but I don''t know how I can access the grid (or any other element) from my user control.

Any Help?

Thanks
Daniel

推荐答案

正确的方法是让父表单为用户控件上的按钮订阅button-click事件.我认为您可能必须将按钮更改为公开按钮才能执行此操作，但是我不记得是否确实需要这样做.

完成此操作后，只需从事件处理程序中以主要形式旋转网格即可.

The proper way to do it is to have the parent form subscribe to the button-click event for the button on the user control. I think you may have to change the button to be public in order to do it, but I don''t remember exactly if that''s necessary.

Once you''ve done that, simply rotate the grid from the event handler in the main form.
