superdom column onrender at fixed interval

[habibalex]

How do I call the onrender function of a superdom column so that I can update it at a fixed interval of time?

Hello,
Thanks for your post.

In order to force OnRender() to be called under a specific condition, call the OnPropertyChanged() method which will force the entire column to repaint. This approach should be used instead of calling OnRender() directly.

It is also important to note that you should limit any calculations or algorithms you may be tempted run in OnRender() simply to rendering. Always favor precomputed values and store them for rendering later as the preferred approach in order to avoid any unforeseen performance issues.

I am including links to our help guide documentation for using OnRender() with the SuperDOM, as well as the OnPropertyChanged() method, for your convenience.
