Hi Rajratna,

Thanks for your update.

You can take a look at the VirtTreeGrid sample, as this uses the sample technique to dynamically show/hide blocks of rows. The idea is to have an array list of visible rowindexes, and then use this array list virtually to display the visible rows.



Maybe something like this would be better than to actually hide large blocks of rows. The hiding of rows with Rows.Hidden is mainly intended for a few rows scattered throughout the grid. It is not intended for large numbers of hidden rows. The virtual technique works better in this case.

Here is the path:

Please let me know if you have any queries.
