I did :

                 gridComplete : function() {
                    var fechaDesde = jQuery("#list").getPostDataItem("desde");
                    jQuery("#dataDiv").hide();

                    if (fechaDesde) {
                        var numRecords = jQuery("#list").getGridParam("records");
                        if (numRecords == 0) {
                          alert("No se consigueron datos para las fechas dadas");
                        } else {
                          jQuery("#dataDiv").show();
                        }
                    }
                }

Note the ar fechaDesde = jQuery("#list").getPostDataItem("desde");

That way I check if I am calling from reloagGrid because I added "desde" as post parameter

Best regards

Hello,

As you said there is ajax call and this call is delayed. So making

trigger("reloadGrid") and after this to get the number of reccord will give

you diffrent results.

My suggestion is to use gridComplete event - this way you will be sure

that all data is loadded and get the number of records.

Regards

Tony

HI!

I wanted to do similar thing: after reloading the grid, display the total of the rows in a separate div. The getGridParam("records") returning null as you, I've found a satisfaying solution:

I use the data type userdata to do so. In the construction of my json response I create a size value with the size of the rows being constructed. I get the value in doing

jQuery(

"#list").getGridParam('userData').size

in the loadComplete event. By the way, the ajax call being asynchronous, I must get my 'size' data in the loadComplete event and not just after the reloading of the grid.

Cordialy,

Geoffroy

I did it using jQuery.getJSON. Here is the code:

jQuery("#list").clearGridData();
                    var url = urlString + "?oper=" + "<%=Constantes.GENERAR_MENSAJE_LIST%>" +
                             "&desde=" + fechaDesdeString + "&hasta=" + fechaHastaString;

                   jQuery.getJSON(url,
                        function(data) {
                            if (data.records == 0) {
                               alert("No se consigueron datos para las fechas dadas");
                               jQuery("#dataDiv").hide();
                            } else {
                                var mygrid = jQuery("#list")[0];
                                mygrid.addJSONData(data);
                                myjsongrid = null;
                                jQuery("#dataDiv").show();
                            }
                        }
                   );

I would like to write jQuery("#list").addJSONData(data) instead of

var mygrid = jQuery("#list")[0];
mygrid.addJSONData(data);
myjsongrid = null;

Maybe in the next release 🙂

I do:

                        jQuery("#list").clearGridData();
                        jQuery("#list").setPostData( { oper: "<%=Constantes.GENERAR_MENSAJE_LIST%>"} );
                        jQuery("#list").appendPostData( { desde: fechaDesdeString, hasta:fechaHastaString });
                        jQuery("#list").trigger("reloadGrid");

                        var numRecords = jQuery("#list").getGridParam("records");
                        alert(numRecords);
                        if (numRecords > 0) {
                            jQuery("#dataDiv").show();
                        } else {
                            alert("No se consigueron datos para las fechas dadas");
                            jQuery("#dataDiv").hide();
                        }

However numRecords comes with null value after reloadGrid (I am pretty sure there is data in my table)

So How can I check this condition ?

TIA
