Why OnLoad() called twice when But predefined Load event executes once When Do RightToLeft?

Something very strange when i search in community. people always said override OnLoad() method because it created Handles and so on. not Predefined event Load

But When doing RightToLeft the OnLoad() called twice unlike Load event which called only once.



Edited

From How to: Enable RTL Mode in a Right-to-Left Culture Application:

At runtime, avoid changing the RightToLeft or RightToLeftLayout property at runtime for forms that are already displayed.

Generally, the Right-to-Left layout is not just flipping a screen but this is a massive change that affects the layout of the controls, their texts, images, and other cultural-specific properties and even more. So the handle recreation and then control's reloading may be an expected behavior in this situation.

Anyway, I suggest you contact the DevExpress Support Team in this regard.

PS. The most appropriate way to change the Right-to-Left mode in this situation is restarting your application with updated cultural settings. Take a look at the Application.Restart as a possible way to accomplish this task.

you may try using onrendered(), it is called only once and when the form is completely loaded.
