[eluser]cestaz18[/eluser]
i have joint table sec_company access table where it has user id and company id joint together where the sec company access id is the one i call to show the detail list data of my master jqgrid table which is the sec user table..

the scene where i have an add delete edit operation in my detail list table which the company detail data..when i have to add data in my company table..it succesfully add but if i refresh the table it will hide and said that no record found..

i think the problem is..there is no company id save in my sec_companyaccess table where its id the one i call on to show the company detail data....

heres my code..

Code:

$(".listFlex").jqGrid({
