/jqgridwiki/doku.php?id=wiki:upgrade_from_3.8_to_4.0.0

shows the replacement for setPostData and appendPostData, however, both replacement are exactly the same function.

jQuery(”#grid_id”).jqGrid('setGridParam',{postData:newdata})

This will always execute the equivalent of the old appendPostData, so it is not possible to do an setPostData

This is correct indeed. Try:

jQuery(“#grid_id”).jqGrid('setGridParam',{postData:{my_existing_key_in_postData:newvalue}});

Maybe I'm missing something but:
$(“#grid”).jqGrid('setGridParam',{postData:{id:1,text:'something'}})

To mimic exactley the old behaviour do:

$(“#grid”).jqGrid(“setGridParam”,{postData:{}});

$(“#grid”).jqGrid(“setGridParam”,{postData:{ .. other values here..} });

Will update the docs

I guess I'm not so happy with this breaking change… it means changing quite some code… may I please urge you to try to keep the interface a stable as possible. Is this kind of change really necessary, I don't understand the benefit of the change…

1. Even so, the proposed solution does not work, even after $(“#grid”).jqGrid(“setGridParam”,{postData:{}});
postData still contains all previous values

Opps,

try to replace

$(“#grid”).jqGrid(“setGridParam”,{postData:{}});

with

$(“#grid”).jqGrid(“setGridParam”,{postData: null });

this works… but please, please, please keep jqGrid API changes to an absolute minimum… this has kept me busy for days (it was already hard to find what was wrong, let alone to find a way to fix it, and to run through all code to add an extra line)

what about the other cases? how about userdata?
