When I use scroll: 1 to make my jqGrid scrollable, it appears to work with tables of about 500,000 rows but above that it seems to freak out.

I changed scroll: false to get paginated and happily worked with the same table that has 800,000+ rows.

Is this a limit of the scrolling list (I have not found any reference to a limit in this regard).

Is there a workaround I can do to allow scrolling of 500,000+ records in jqGrid?


Thanks

Hello,

Actually there is no limitation. Your code will work in IE, Safari, but not in FF.

This is a bug where we can not fix easy.

The real problem is that the FireFox stores the height in integer and not in long integer, (I do not know how is with FF3.6)

so having more than 500000 multiple by example 20-22px of the row height give you a number for the height which can not be interpreted correct in FF .

We have try to fix this, but for now without success.

Thanks for remainding this.

Best Regards

Tony

Hi Tony,


Thanks for the reply and confirmation that there is a limit to the number of rows supported (tho what that number is is variable).


I can not imagine why jqGrid needs to know the theoretical height of all rows if displayed at once considering we only see a few records at a time – being the nature of scroll: 1.  However I will leave this up to you and look forward to hearing how we can avoid this in the future.


Thanks

It does not work correctly in IE either. At least not in IE8.
