Save data in the grid during page change

Question

Hi,

I'm working on jqgrid. I have successfully loaded the data in the jqgrid. In the grid there is a column where user enter the information. Now I have to save this information back to the SQL server. The problem is that I have 3 pages in jqgrid. If the user enter some information on the first page and then change the page, then the data on the first page gets lost. I want to save this data. Can anyone help me on this?
