Providing Extra Filtering Option in Dhtmlx Grid

How we can filter the grid by matching/comparing the two rows column which is having same data or greater or lower or other some conditions.

Which will give the result when grid filter used or not used.

Currently I am written custom logic which will use matching column and display the result. here to do this i am using setRowHidden function which makes my process very slow.And this operation i dont want to loose any rows.

You can use filterBy() method. Please find tutorial here … :filtering
