  Hi,

  There can be a couple of reasons for this issue. Have you declared the myGrid variable on the template side like this?

  <wj-flex-grid #myGrid ...></wj-flex-grid>
  

  If you have already defined it, it only gets initialized in the ngAfterViewInit event. So, if you need to use this variable, use it in the ngAfterViewInit callback of angular 9. If you are using this variable on a button click (or something like this), then it is fine. You do not need to change it.
  
  Also, can you let me know what exact error is thrown on the console? Is the myGrid variable is undefined or the my.collectionView is undefined? If the collectionView is undefined, then you may not have set the data properly.

  One more thing, only the versions after 5.20193.637 are compatible with angular 9. So, I would suggest you upgrade Wijmo if you are using a lower version than this.

  Regards,
