In our application we are using DHTMLXGrid with pagination and using filters. In the grid Date format data is also visible alsong with text data. The date column uses a filter where user has to enter the filtering data in the rendered Date format.
Upon entering filtering data in Page 1 the grid will filter only Page 1 records, whereas when user loads Page 2 and filters the data it will consider Page 1 and Page 2 data. Whereas in case of text filters in Page 1 the filtering applies on whole grid data.
