Hello,

You will need maybe to increase the rowNum parameter of the grid to let say 500

You should understand that everthing is done at client side and the grid load 150 records.

From where should know the grid that there are a lot of other rows and thier values?

Just think about this.

Regards

Tony

Thanks Tony for your reply, but, it seems what you saying is that the number of rows per page should be the sequal to or greater than the number of rows in the largest group.
