Group By is freezing when column is in the far right of the grid

[Victor Andales]

We have a huge grid with no paging.

We wanted to group by a column where we need to scroll horizontally to the right to find and drag that header to the group by box.

This action will freeze the grid. Please help.

Below is our grid properties with over 50 columns

  <ej-grid #gridid id="gridid" [dataSource]='ExceptionRows' [allowSorting]='true' [allowFiltering]='true'
    [allowGrouping]='groupByVisible' [allowReordering]='true' (toolbarClick)='clickHandler($event)' [allowResizing]='true'
    [toolbar]='toolbarOptions' [showColumnChooser]='true' [pageSettings]='options' [enableVirtualization]=true [enableColumnVirtualization]=true
    gridLines='vertical' [filterSettings]='filterSettings' [height]='gridHeight'>
 <e-columns>
 ...50+ columns
 </e-columns>
  </ej-grid>

Hi Victor, 

We have checked your code example and the cause of the issue is maximum call stack size exceeded script error throws when we scroll to the right end and grouping the column while grid is enabled with column virtualization and large number of columns. We have confirmed “ Grouping with column virtualization throws maximum call stack size exceeded script error while having large number of columns” as a defect and logged a report for the same. The Fix will be available in our January 17, 2018 release.
