The last row is not visible when grouping get used
posted

Hi there, 

There are couple of issues related with visibility of the rows when we use `groupingExpressions`

When grouping by some column is enabled then it's counted on as an item as well
If some of the row gets collapsed then more rows appeared from the bottom 

Such behaviour can be observed in the example as well https://es.infragistics.com/products/ignite-ui-react/react/components/grids/grid/groupby#react-group-by-with-paging-example

    Hello Constantine,

    My team and I have done an initial review of this post, and the behavior you are seeing is actually completely expected and by design. This is documented just above the example that you linked, where the documentation states: “Group rows participate in the paging process along with data rows. They count towards the page size for each page. Collapsed rows are not included in the paging process.”

    This is why you are seeing more rows appearing from the bottom when you collapse some of the groups. The group-by rows are counted toward the “Items per Page” when paging the grid, and if the group row is collapsed, the rows that are children of that group row will not be counted and the grid will back-fill the rest of the items with the next group.

    Please let me know if you have any other questions or concerns on this matter.
