  Hello,

  As per the above-shared image, this.cmData variable contains the collectionView therefore if you wish to iterate over the collectionView items then you may iterate over the collectionView’s sourceCollection property array holding the data items.

  Please refer to the sample link below for reference, in the sample below the data isn’t hierarchal so I created a list to show, if you have hierarchal structured data then you may do as per your requirement:

  Hello,

  You may try to refresh the collectionView in order to update the grid data collection. Please refer to the code snippet for reference:

  
  multiRow.collectionView.refresh();
  
  

  However, I’m not sure how you are adding the data here, it would be helpful if you could provide some more detailed information or a sample to replicate the issue.

  Regards

  Hello,

  As per the observation based on the shared images, you may update the code shown in image 2 from item.measures.push(item) to item.measures = […item.measures, item]. This should fix the issue.
