Hi,

try the demo (see the answer). Is it what you try to implement?

Best regards

You post small code fragments only, so it's difficul to understand what you do. I don't understand which relation has your last post to your original question (custom grouping header). The option data (returned by $(this).jqGrid(“getGridParam”, “data”);) are defined only if you use datatype: “local”. I don't see any sense to use $(this).jqGrid(“getGridParam”, “data”); inside of formatter. Formatter callback has rowObject parameter, which contains the data of the currect row. The exact value can depend on other jqGrid parameters (datatype, loadonce) which you use. In general rowObject.NameListe provides probably the value which you need.
