Question

I am using the jqGrid with loadonece: true. I am using client side sorting and filtering. I got the script unresponsive error when I tried to search in a grid with 8000 records. So I was wondering if there in any limitation on data. Though in jqGrid documentation I did not find any limitation on data size with loadonce:true.

Answer 1

The restriction is very depend on

• web browser which you use. IE6 have vary slow JavaScript engine for example, Google Chrome has quick engine. Every new version of every web browser improve the performance of JavaScript.
• The options of jqGrid which you use. If you use large page size (rowNum value) it’s very important to use gridview: true option (see the answer for more information). You should reduce the usage of methods like setCell or setRowData especially in the loop (for example the loop over all rows inside of loadComplete or gridComplete). Instead of that one should use cellattr, rowattr and custom formatters.
• The number of columns which you use (inclusive hidden rows). Grid with many columns reduce the performance of grid.

In general I would not use local grid with 8000 rows. The performance of local grid with more as about 1000 rows is slow enough. I would recommend you to use server side paging, sorting and filtering. SQL Server which implement all the feature in native code and which can use indexes from the database can implement all much more effectively as JavaScript can do.
