  I have a grid view which has limited cell is 50.
  
  when i insert a new cell by command grid.rows.insert(idx, row) with idx = 0;
  
  that mean i want insert a new cell to top of the grid.
  
  The new grid i have still have only 50 cell.
  
  After that. i copy a content like
  
  1
  
  2
  
  3
  
  …
  
  50
  
  and move the mouse to the new row and press Ctrl + V to paste
  
  After that i meet the issue

  1. The first row is empty and can’t paste the data
  2. The Grid length is not 50 anymore. it come to 51 cell. And i have two cell have content is 50 ( cell number 50 and 51).
  3. After a while ( by using scroll to scroll up and down ) the row number 51 is dissapper.

  grid.row.insert() method works well with unbound grids but for bound grids, we need to push new dataItem on the grid’s collectionView to insert a new row.
  
  Please refer to the following code snippet:

  grid.collectionView.sourceCollection.splice(0, 0, {});
    grid.collectionView.refresh();
  

  You may also refer to the following sample: https://stackblitz.com/edit/js-cbnmkp?file=index.js

  Please let us know if the solution doesn’t work for you.
