Attempting to load data from server based off of multisearch/filters, but do sorting and paging on client. i have found a few posts that say to simply set the datatype back to the original value in the beforeSearch method.
i have attempted this and it does execute against the server and return the correct data. However, the second time i filter it seems to get the data from the server but then it gets wiped out on line 4429 in the jqgrid code shown below. Any idea on how to achieve this goal?
Ln 4429 : p.lastSelectedData = query.select();
grid definition:
$element
.jqGrid({
cmTemplate: { search: true, searchoptions: { attr: { placeholder: "filter..." }, clearSearch: true }, sortable: true, align: "center" },
colModel: [
{ name: "Id", key: true, hidden: true, searchoptions: { searchhidden: true, sopt: ["eq"] } },
{ name: "TransmissionId", label: "Transmission Id", searchoptions: { sopt: ["eq"] } },
{ name: "Name", label: "Name", searchoptions: { sopt: ["cn"] } }
],
datatype: "json",
loadonce: true,
height: "auto",
ignoreCase: true,
pager: $("#" + pagerId),
pgbuttons: true,
pginput: false,
rowList: [10, 25, 50],
rowNum: 10,
toppager: true,
url: "url here",
loadComplete: function (data) {
if (this.p.datatype === "json") {
setTimeout(function () {
$element.trigger("reloadGrid", [{ page: 1 }]);
}, 50);
}
return data;
},
viewrecords: true
})
.jqGrid("filterToolbar", {
autosearch: true,
defaultSearch: "cn",
beforeSearch: function () {
$element.setGridParam({ datatype: "json", page: 1 });
}
})
.jqGrid("navGrid", "#" + pagerId, {
edit: false,
add: false,
del: false,
refresh: false,
view: false,
cloneToTop: true
});
I have trimmed down the grid to try to verify it is not custom logic that is causing this issue. the grid does have multipleSearch on. but is not defined above.
If I understand correctly your question then you should use forceClientSorting: true in combination with loadonce: true. It force that the data loaded from the server will be sorted, filtered and paged locally directly after loading from the server. Thus you can remove loadComplete, which you use currently. See the answer for a demo.
Additionally, you can add searching property, where you include all options of filterToolbar and searchGrid:
searching: {
autosearch: true,
defaultSearch: "cn",
beforeSearch: function () {
var p = $(this).jqGrid("getGridParam"), // get reference to all parameters
filters = JSON.parse(p.postData.filters);
p.datatype = "json";
// one can here analyse filters, modify it or clear it as
p.postData.filters = "";
// one can set any other parameters, which will be sent to the server
// by using p.postData.param1 = "value1";
// which will sent param1=value1 to the server.
}
}
In general you can do the same inside your current beforeSearch too.
UPDATED: Probably you should use beforeProcessing callback additionally. beforeProcessing will be called directly after receiving the data from the server. Inside of the callback you can clean-up all p.postData.filters (to "") and p.search (change it from true to false). As the result jqGrid will not try to filter locally by postData.filters the data returned from the server.
My subgrid only shows the column headers but not not load the json data from the main grid. The columns are empty. I followed the tutorial on JQuery Grid-SubGrid for Parent-Child relation
but it does not work.
This is my javascript code:
jQuery().ready(function () {
var grid = jQuery("#shipment_grid");
var mainGridPrefix = "s_";
grid.jqGrid({
url: '${pageContext.request.contextPath}/getTruckShipmentJSONAction?truckId=' + <c:out value="${truckId}" />,
datatype: "json",
mtype: 'GET',
loadonce: true,
colNames: ['Lead Tracking #'],
colModel: [
{name: 'trackingNr', index: 'trackingNr', width: 100, align: 'left'}
],
rowNum: 10,
height: 230,
width: 700,
idPrefix: mainGridPrefix,
autoheight: true,
rowList: [10, 20, 30],
pager: jQuery('#shipment_grid_pager'),
sortname: 'trackingNr',
sortorder: "desc",
jsonReader: {
root: "records",
page: "page",
total: "total",
records: "rows",
repeatitems: false
},
viewrecords: true,
altRows: false,
gridview: true,
multiselect:true,
hidegrid: false,
shrinkToFit: true,
forceFit: true,
idPrefix: mainGridPrefix,
caption: "Shipments Overview",
subGrid: true,
beforeProcessing: function(data) {
//align 'Lead Tracking #' column header to the left
grid.jqGrid ('setLabel', 'trackingNr', '', {'text-align':'left'});
var rows = data.rows, l = rows.length, i, item, subgrids = {};
for (i = 0; i < l; i++) {
item = rows[i];
if (item.shipUnitView) {
subgrids[item.id] = item.shipUnitView;
}
}
data.userdata = subgrids;
},
subGridRowExpanded: function (subgridDivId, rowId) {
var $subgrid = $("<table id='" + subgridDivId + "_t'></table>"),
pureRowId = $.jgrid.stripPref(mainGridPrefix, rowId),
subgrids = $(this).jqGrid("getGridParam", "userData");
$subgrid.appendTo("#" + $.jgrid.jqID(subgridDivId));
$subgrid.jqGrid({
datatype: "local",
data: subgrids[pureRowId],
colNames: ['Ship Type (Pallet / Carton)', 'Ship Unit (Pallet ID / Cone #)', 'Total Cartons'],
colModel: [
{ name: "shipUnitType", index: 'shipUnitType', width: 100, align: 'center'},
{ name: "reference", index: 'reference', width: 100, align: 'center'},
{ name: "totalOfCartons", index: 'totalOfCartons', width: 100, align: 'center'}
],
sortname: "shipUnitType",
sortorder: "desc",
height: "100%",
rowNum: 10,
autowidth: true,
autoencode: true,
jsonReader: {
root: "records",
records: "rows",
repeatitems: false,
id: "reference" },
gridview: true,
idPrefix: rowId + "_"
});
}
}).navGrid('#shipment_grid_pager', {edit: false, add: false, del: false, search: false, refresh: true});
});
This is my json data from the server:
{"page":1,
"records":[
{"id":2,"trackingNr":"1Z1484366620874728",
"shipUnitView":[{"reference":"65000943","shipUnitType":"CARTON","totalOfCartons":1},
{"reference":"65000942","shipUnitType":"CARTON","totalOfCartons":1}]},
{"id":4, "trackingNr":"1Z1484366620874746"
"shipUnitView":[{"reference":"65000940","shipUnitType":"CARTON","totalOfCartons":1},
{"reference":"65000939","shipUnitType":"CARTON","totalOfCartons":1}]},
{"id":3, "trackingNr":"1Z1484366620874764"
"shipUnitView":[{"reference":"65000938","shipUnitType":"CARTON","totalOfCartons":1},
{"reference":"65000937","shipUnitType":"CARTON","totalOfCartons":1}]}
],
"recordsTotal":3,"rows":10,"sidx":null,"sord":"asc","total":1,"trackingNr":null,"truckId":"174225","truckShipmentComponent":{}}
First of all there are small errors in the JSON data which you posted. It contains no commas after "trackingNr":"1Z1484366620874746" and "trackingNr":"1Z1484366620874764". I hope that it's only cut&paste error during preparing the data for the question. In any way it would be more safe to include loadError callback (see the answer) in case of loading errors.
Your main error seems to me are inside of beforeProcessing callback. The data parameter of the callback contains the server response. The array of items you have inside of data.records, but you use var rows = data.rows, ... instead. The line should be fixed to var rows = data.records, ....
One asked you in the comment to prepare JSFiddle demo which demonstrates the problem and you had problems to prepare it because of usage datatype: "json". On the other side JSFiddle do provides you possibility to implement demos in the case. One can use Echo service. In case of jqGrid one needs just use mtype: "POST" and url: "/echo/json/". To inform echo service which data you want to have one need just send JSON encoded data in json parameter. So the fill looks like
// the data which we want to receive back
var serverResponse = {
"page":1,
...
};
$("#gridId").jqGrid({
url: "/echo/json/", // use JSFiddle echo service
postData: {
json: JSON.stringify(serverResponse) // needed for JSFiddle echo service
},
datatype: "json",
mtype: "POST", // needed for JSFiddle echo service
...
});
The working JSFiddle demo you can find here: http://jsfiddle.net/OlegKi/ntfw57zm/. I makes some small additional optimization of your code.
I hope the example could help other people to post his questions with JSFiddle demos.
This is my Jsp Page using jQuery
jQuery("#jqGrid01").jqGrid({
url: "JqGridDemoJson.action",
datatype:"json",
height: 200,
rowNum: 10,
rowList: [10,20,30],
colNames:['Inv No','Name'],
colModel:[
{name:'id',index:'id', editable: true,sorttype:"int",search:true},
{name:'name',index:'name', editable: true,width:30}
],
pager: "#jqGridPager01",
viewrecords: true,
add: true,
edit: true,
addtext: 'Add',
edittext: 'Edit',
caption: "Data",
hidegrid:false
});
This is my action retriveing list:
{"JQgridAction":"success",
"mitnolist":
[{"id":1,"name":"MIT\/1009\/SUF-"},
{"id":2,"name":"MIT\/1010\/SUF-"},
{"id":5,"name":"MIT\/1011\/SUF-Adma Site"},
]}
This list unable to load on the above JQgrid.
Your json is an object while jqgrid uses [{}, {}, {},...] array of multiple objects so you have to return your json as this example:
[{"id":1,"name":"MIT\/1009\/SUF-"},
{"id":2,"name":"MIT\/1010\/SUF-"},
{"id":5,"name":"MIT\/1011\/SUF-Adma Site"}]
or there is another way that you write a js ajax function and pass the required data to your jqgrid:
$.ajax({
url: "JqGridDemoJson.action",
dataType: 'json',
type: 'post',
success: function(data){
makeGrid(data.mitnolist); // as this seems to be populated in grid
}
});
now in your jqgrid you can do this:
function makeGrid(gData){ // pass in args
$("#grid").jqGrid({
data: gData, // your data to populate in grid
datatype: "local", // now change the datatype to local
.....
});
}
A small working example.
I'm trying to populate a JqGrid inside the success function of an Ajax call. My ajax call is passing a date parameter to the function which will filter the results. My grid loads, but no data is displayed and it says Loading... above my grids caption. I'm using a drop down to filter results based on date. My json data has been verified to be valid.
$(document).ready(function () {
$("[name='DDLItems']").change(function () {
var selection = $(this).val();
var dataToSend = {
//holds selected value
idDate: selection
};
$.ajax({
type: "POST",
url: "Invoice/Filter",
data: dataToSend,
success: function (dataJson) {
// alert(JSON.stringify(dataJson));
$("#grid").jqGrid({ //set your grid id
data: dataJson, //insert data from the data object we created above
datatype: json,
mtype: 'GET',
contentType: "application/json; charset=utf-8",
width: 500, //specify width; optional
colNames: ['Invoice_Numbers', 'Amt_Totals','f', 'ff', 't'], //define column names
colModel: [
{ name: 'Invoice_Number', index: 'Invoice_Number', key: true, width: 50 },
{ name: 'Amt_Total', index: 'Amt_Total', width: 50 },
{ name: 'Amt_Due', index: 'Amt_Due', width: 50 },
{ name: 'Amt_Paid', index: 'Amt_Paid', width: 50 },
{ name: 'Due_Date', index: 'Due_Date', width: 50 },
], //define column models
pager: jQuery('#pager'), //set your pager div id
sortname: 'Invoice_Number', //the column according to which data is to be sorted; optional
viewrecords: false, //if true, displays the total number of records, etc. as: "View X to Y out of Z” optional
sortorder: "asc", //sort order; optional
caption: "jqGrid Example", //title of grid
});
},
-- controller
[HttpPost] // Selected DDL value
public JsonResult Filter(int idDate)
{
switch (idDate)
// switch statement goes here
var dataJson = new UserBAL().GetInvoice(date);
return Json(new { agent = dataJson}, JsonRequestBehavior.AllowGet);
Here's the answer if anyone else comes across this. This is what I ended up doing, the rows are getting filtered passed on the date parameter I'm passing to the URL of the function. Having the Grid populate inside the Ajax call also seemed like it was a problem so I had to take it out.
public JsonResult JqGrid(int idDate)
{
switch (idDate)
#region switch date
--Switch Statement--
#endregion
var invoices = new UserBAL().GetInvoice(date);
return Json(invoices, JsonRequestBehavior.AllowGet);
}
[HttpPost] // pretty much does nothing, used as a middle man for ajax call
public JsonResult JqGridz(int idDate)
{
switch (idDate)
#region switch date
--Switch Statement--
#endregion
var invoices = new UserBAL().GetInvoice(date);
return Json(invoices, JsonRequestBehavior.AllowGet);
}
Yes these two functions seem very redundant and they are. I don't know why my post wouldn't update data, but I needed to reload the grid each time and when I did that it would call the first function. So yea the post jqGridz is kinda of just a middle man.
Here's the jquery code I used
var dropdown
var Url = '/Invoice/JqGrid/?idDate=0'
$(document).ready(function () {
$("#jqgrid").jqGrid({
url: Url,
datatype: 'json',
mtype: 'GET', //insert data from the data object we created above
width: 500,
colNames: ['ID','Invoice #', 'Total Amount', 'Amount Due', 'Amount Paid', 'Due Date'], //define column names
colModel: [
{ name: 'InvoiceID', index: 'Invoice_Number', key: true, hidden: true, width: 50, align: 'left' },
{ name: 'Invoice_Number', index: 'Invoice_Number', width: 50, align: 'left'},
{ name: 'Amt_Total', index: 'Amt_Total', width: 50, align: 'left' },
{ name: 'Amt_Due', index: 'Amt_Due', width: 50, align: 'left' },
{ name: 'Amt_Paid', index: 'Amt_Paid', width: 50, align: 'left' },
{ name: 'Due_Date', index: 'Due_Date', formatter: "date", formatoptions: { "srcformat": "Y-m-d", newformat: "m/d/Y" }, width: 50, align: 'left' },
],
pager: jQuery('#pager'),
sortname: 'Invoice_Number',
viewrecords: false,
editable: true,
sortorder: "asc",
caption: "Invoices",
});
$("[name='DDLItems']").change(function () {
var selection = $(this).val();
dropdown = {
//holds selected value
idDate: selection
};
$.ajax({
type: "POST",
url: "Invoice/JqGridz",
data: dropdown,
async: false,
cache: false,
success: function (data) {
$("#jqgrid").setGridParam({ url: Url + selection})
$("#jqgrid").trigger('reloadGrid');
}
})
})
});
Are you actually passing a value to your controller? I see you have data: dataToSend which doesn't match to your controllers idDate.
Is there a reason you are trying to setup your grid this way? Do you not want to deal with paging, or I'm not even sure if your setup would handle rebuild a grid when a user picks the date for a 2nd time.
My personal suggestion would be that you:
setup your grid separately, hidden if you don't want it visible on page load
set it's datatype to local so the grid doesn't load on page load
on the change event:
show the grid
change the postdata parameter the grid has
set the url of the controller/action which will feed the data back to the grid
trigger a grid reload
I have a Jqgrid which requires editing. I have successfully managed to configure the grid to save the data after editing, however the issue is that when the data is saved the grid is not refreshed with the data present in the database. For example the version field is automatically updated by the application backend however after a edit is done it is not refreshed and the old value is shown. I have tried
afterSubmit
afterComplete
which did not work. I also placed an alert in it to verify that the function was called however the alert was not shown either. Additionally I set loadonce to false and reloadaftersubmit to true but this did not work either. I think the issue could be that I either havent configured the edit correctly or placed the above mention parameters in the incorrect location.
After a save is done (edit) the updated data (which is the WHOLE page) is returned to the Jqgrid (as json). The issue here is that the old data is shown and how do I display this updated data after the edit.
UPDATE : I found out that when I edit via the popup box the afterSubmit is executed. HOWEVER the editing takes place via the formatoptions which allows to edit the data in the table itself. Now when the data is edited and saved from the grid itself without the use of the popup I want an afterSubmit to fire to refresh the table. Where do I place my afterSubmit / How do I achieve this.

add: true,
del:true,refresh:false},
{ // edit options
afterSubmit: function() {
comptes[0].clearToolbar();
comptes.jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid');
return [true,'',false]; // no error and no new rowid
}
},
{ // add options
afterSubmit: function() {
comptes[0].clearToolbar();
comptes.jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid');
return [true,'']; // no error
}
} ,
{ // delete options
afterSubmit: function() {
comptes[0].clearToolbar();
comptes.jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid');
return [true,'']; // no error
}
}
);
Try to reload jqGrid with new data after all your editing process as following:
jQuery("#grid").jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid');
