Hi I am not able to get the data from JSON loaded on to grid,
HEre is my code for the grid wich displays the stock prices for the stock for a user :
$(document).ready(function () {
// $("#jQGrid").html("<table id=\"list\"></table><div id=\"page\"></div>");
jQuery("#jqTable").jqGrid({
url:jqDataUrl,
datatype: "json",
mtype: "POST",
height: 250,
// Specify the column names
colNames: ["SYMBOL", "LAST", "CHANGE", "%CHANGE","HIGH/LOW"],
// Configure the columns
colModel: [
{ name: "SYMBOL", index: "SYMBOL", width: 200, align: "left" },
{ name: "LAST", index: "LAST", width: 200, align: "left" },
{ name: "CHANGE", index: "CHANGE", width: 200, align: "left" },
{ name: "%CHANGE", index: "%CHANGE", width: 200, align: "left"},
{ name: "HIGH/LOW", index: "HIGH/LOW", width: 200, align: "left"}
],
jsonReader : {
root: "rows",
page: "page",
total: "total",
records: "records",
cell: "cell",
id: "id",
},
multiselect: false,
// paging: true,
// rowNum:10,
// rowList:[10,20,30],
pager: $("#jqTablePager"),
loadonce:true,
caption: "WatchList"
}).navGrid('#jqTablePager',{edit:false,add:true,del:true});
}
});
But when i try and run the code i am not able to get the contents on to the table (but the grid loads with no content)
And My json is of the form :
{
total: "1",
page: "1",
records: "2",
rows :
[
{id:"1", cell:["cell11", "cell12", "cell13","cell13","cell13"]},
{id:"2", cell:["cell21", "cell22", "cell23","cell13","cell13"]}
]
}
Please help me solve the problem
UPDATE:
I discovered that if you do not put repeatitems:true option into json reader, jqGrid assumes that you are using json dot notation. When you put it into jsonReader, your data is properly loaded. Here is working example: http://jsfiddle.net/a5e5F/3/
Old version:
I played a lot with your jqgrid code, and it seems that there is a bug in this version of jqGrid, which causes your jsonReader not to work. It reads data directly, ignoring root element and assuming that your data is array of json objects in format
{propertyName1:'PropertyValue1', propertyName2:'PropertyValue2', ...}
You can see what I mean on http://jsfiddle.net/a5e5F/2/
If you replace data:rows with data:data (your format of data), it does not load data. Maybe you should try to change your json data to use real json format (with properties named as columns)?
I have been trying a ton of stuff, changing column names to check for issue in #Barmar's coment, which I also thought it is the cause.

I have the code available here: https://jsfiddle.net/zqLp4yrg/41/
datatype is "local" not json.
$("#jqGrid").jqGrid({
url: "/echo/json/", // use JSFiddle echo service
postData: {
json: JSON.stringify(serverResponse) // needed for JSFiddle echo service
},
mtype: "POST", // needed for JSFiddle echo service
datatype: "json",
colModel: [
{ label: 'CatId', name: 'CatId', key: true, width: 30 },
{ label: 'InventoryDate', name: 'InventoryDate', width: 70 },
{ label: 'ProductName', name: 'ProductName', width: 150 },
{ label: 'RemainingQuantity', name: 'RemainingQuantity', width: 150, summaryType: 'sum', sortable: true }
],
iconSet: "fontAwesome",
viewrecords: true,
rowList: [20,30,50],
width: 780,
height: 250,
rowNum: 20,
sortname: "ProductName",
grouping: true,
groupingView: {
groupField: ["CatId"],
groupColumnShow: [true],
groupText: [
"CatId: <b>{0}</b>"
],
groupOrder: ["asc"],
groupSummary: [true],
groupSummaryPos: ["header"],
groupCollapse: true
}
});
In here I want to sort the Remaining quantity based on its summary value in header. Please help.
Your demo has many small problems:
First of all you write about the usage of datatype is "local", but you use datatype: "json" in the demo. Moreover, you use no loadonce: true option and no forceClientSorting: true option. It means that the server is responsible for sorting the data. Moreover, if you use grouping, then the data returned from the server have to be sorted (on the server) by both groupingView.groupField (CatId in your case) and then by sortname (RemainingQuantity in your case). The data which you use as the source are not sorted correctly. One sees, for example, that jqGrid displays two CatId: 2 and two CatId: 3 groups.
You can fix the problem by adding loadonce: true and forceClientSorting: true options, but you use old version of free jqGrid (4.11.1), which is not support forceClientSorting: true. You have to upgrade to the latest version (4.14.0) of free jqGrid to be able to sort and group the data returned from the server on the client before displaying.
The source data, which contains integer data will be returned from the server as strings. Moreover, some data items contains spaces (" 16" instead of "16" or 16). It changes the order of sorting the data.
You should use sorttype (for example sorttype: "integer") to sort the data in the column corresponds to the type of the data.
To sort the date column correctly you should use both sorttype: "date" and the formatter: "date" with the formatoptions (in you case: formatoptions: { srcformat: "d/m/Y H:i:s", newformat: "d/m/Y H:i:s" })
If you want that the options rowNum, rowList and viewrecords work, then the grid have to have at least one pager. Thus you probably skip pager: true or toppager: true (or both) options.
The fixed demo is https://jsfiddle.net/OlegKi/zqLp4yrg/43/. I removed groupingView.groupollapse: true and height: 250 only to make easy to examine the results. The settings are not important for your main problem.
Im trying to put some data into jqGrid and force it to be displayed in a treeview.
My problem is, the 6th item (cid=6) is not showing in the grid. The 4th item looks like it has some subitems, but expanding this branch shows nothing. The 6th item is nowhere to find in the tree (I suppose, I've defined it as subitem of cid4).
Here is a working example of this code http://jsfiddle.net/498jhxcg/
(my production code uses POST/AJAX/JSON, the example is changed to localdata. Grid is displayed in the same wrong way in both cases.)
Is the data in wrong format, or the jqgrid is wrong defined? (btw. changing parent_id to parentid did not helped.)
var myjsondata = '{"rows":[
{"cid":"1","name":"cat1","lvl":"0","parent_id":"null","isleaf":true,"expanded":false,"loaded":true},
{"cid":"2","name":"cat2","lvl":"0","parent_id":"null","isleaf":false,"expanded":false,"loaded":true},
{"cid":"3","name":"cat3","lvl":"1","parent_id":"2","isleaf":true,"expanded":false,"loaded":true},
{"cid":"7","name":"cat7","lvl":"1","parent_id":"2","isleaf":true,"expanded":false,"loaded":true},
{"cid":"4","name":"cat4","lvl":"0","parent_id":"null","isleaf":false,"expanded":false,"loaded":true},
{"cid":"6","name":"cat6","lvl":"1","parent_id":"4","isleaf":true,"expanded":false,"loaded":true},
{"cid":"5","name":"cat5","lvl":"0","parent_id":"null","isleaf":true,"expanded":false,"loaded":true}
],"records":7,"total":1}';
$('#jgtable').jqGrid({
ExpandColumn:'id',
datastr: myjsondata,
datatype: 'jsonstring',
colNames: [
'Id',
'Name',
'Parent id',
'isLeaf?',
],
colModel: [
{ index: 'cid', name: 'cid', width:"75px"},
{ index: 'name', name: 'name', width:"75px"},
{ index: 'parent_id', name: 'parent_id',width:"75px"},
{ index: 'isleaf', name: 'isleaf', width:"75px"},
],
pager: '#pager',
rowNum: 10,
rowList:[2, 10, 25, 50, ],
height: 'auto',
minHeight: '250px',
recordpos: 'right',
viewrecords: true,
gridview: false,
treeGrid: true,
treeGridModel : 'adjacency',
treedatatype: "local",
treeReader : {
level_field: "lvl",
parent_id_field: "parent_id",
leaf_field: "isleaf",
expanded_field: "expanded",
loaded_field: "loaded",
index_field: "cid",
},
jsonReader: {
repeatitems: false,
},
});
It seems to me that you should add key: true property to the definition of cid column. You can use alternatively (or to do both things) the option jsonReader: { id: "cid" }. In the case the value of cid property of input data will be interpreted as the id of the item and the value from parent_id will be correct.

Hi I am trying to get showlink formatter working by following this document from trirand.
What I want to achieve is a hyperlink I can click for a edit view to update/edit records. But for some reason, the column are empty where I want show a hyperlink.
Here is my code snippets, and link is the last column:
<script type="text/javascript">
$(document).ready(function () {
$("#grid_products").jqGrid({
jsonReader: {
repeatitems: false,
id: 'Guid'
},
url: '/Product/jqgridJSON/',
datatype: 'json',
mtype: 'GET',
colNames: ['ProductCode', 'ProductDescription', 'DefaultSellPrice', 'LastCost', 'Edit'],
colModel: [
{ name: 'ProductCode', index: 'Productcode' },
{ name: 'ProductDescription', index: 'ProductDescription' },
{ name: 'DefaultSellPrice', formatter: 'currency', index: 'DefaultSellPrice' },
{ name: 'LastCost', formatter: 'currency', index: 'LastCost' },
{ name: 'MyLink',
edittype: 'select',
formatter: 'showlink',
formatoptions: { baseLinkUrl: '/Product/Update/', idName: 'Guid' }
},
],
pager: '#pager',
rowNum: 10,
rowList: [20, 50, 100, 200],
sortname: 'ProductCode',
sortorder: 'asc',
viewrecords: true,
width: 'auto',
height: 'auto',
caption: 'Products'
}).navGrid('#pager', { edit: true, add: false, del: false });
});
</script>
#{
ViewBag.Title = "JSONGrid";
}
<h2>JSONGrid</h2>
<table id="grid_products"></table>
<div id="pager"></div>
The formatter from jqGrid is working for currency, but for some reason, it just didn't shown for hyperlink.
Update:
Got it working by using custom formatter.
...
{ name: 'MyLink',
formatter: myLinkFormatter,
},
...
function myLinkFormatter (cellvalue, options, rowObjcet) {
return 'Edit this product';
}
I suppose that you fill no value in JSON input for the 'MyLink' column. Because of this the hyperlink is empty. If you want to place the link with any fixed text in column I would recommend you to use custom formatter. See the recent answer for an example.
One more possible solution way is to use formatter: 'showlink' and include jsonmap: function() { return "Edit"; } to the 'MyLink' column definition. In the case you will not need to include in the JSON data "MyLink":"Edit" for every row of data. It's important to understand that the trick works only in case of usage jsonReader: {repeatitems: false} (so it should work for your grid).
If you have another problem you should include in the text of your question the JSON data which you use.
Some small remarks to your current code:
the usage of edittype: 'select' together with formatter: 'showlink' has no sense. You should remove it if you will do use formatter: 'showlink'.
the parameter height: 'atuo' should be height: 'auto'.
pager: $('#pager') is better to replace to pager: '#pager'. If you use pager: $('#pager'), the jqGrid will replace it internally to pager: '#pager' and the object $('#pager') will be discarded.
If you use jsonReader: { id: 'Guid'} and you don't plan to show the guids to the user you can remove the 'Guid' column from the grid. The id (the Guid in your case) will be used to assign ids of <tr> elements (table rows) of the grid. So you don't need to hold the same information twice
I have this jqGrid:
$("#report").jqGrid( {
url: '/py/db?coll=report',
datatype: 'json',
height: 250,
colNames: ['ACN', 'Status', 'Amount'],
colModel: [ {name:'acn', sortable:true},
{name:'meta.status', sortable:true},
{name:'amount'} ],
caption: 'Show Report',
rownumbers: true,
gridview: true,
rowNum: 10,
rowList: [10,20,30],
pager: '#report_pager',
viewrecords: true,
sortname: 'acn',
sortorder: "desc",
altRows: true,
loadonce: true,
mtype: "GET",
rowTotal: 1000,
jsonReader: {
root: "rows",
page: "page",
total: "total",
records: "records",
repeatitems: false,
id: "acn"
}
});
Notice that the column 'meta.status' is in JSON dot notation and accordingly the data sent from the server is like this:
{"page": "1", "total": "1", "records": "5", "rows": [
{"acn":1,"meta": {"status":"Confirmed"}, "amount": 50},
{"acn":2,"meta": {"status":"Started"}, "amount": 51},
{"acn":3,"meta": {"status":"Stopped"}, "amount": 52},
{"acn":4,"meta": {"status":"Working"}, "amount": 53},
{"acn":5,"meta": {"status":"Started"}, "amount": 54} ] }
The problems are of two fold:
Sorting does not work on columns with dot notation, here "meta.status". It does not even show the sortable icons on the column header, and nothing happens even if the header is clicked. Sorting does not work, whether loadonce is true or false.
If I try Searching (after setting loadonce to true) for the column meta.status (other columns without dot notation is okay), then it throws up a javascript error like this.
After changing of the definition of the last column from {name:amount} to {name:'amount'} I could reproduce your problem: the sorting on 'Status' not work, but I could not see any error message (see the demo).
One can fix the problem it one change the definition of the second column from
{name:'meta.status', sortable:true}
to
{name:'status', sortable:true, jsonmap: "meta.status"}
See the fixed demo here.
As a rule of thumb to avoid this problem:
Ensure that your name and index values are the same
name: 'Date', index: 'Date',
name: 'Clicks', index: 'Clicks',
...
Ensure you set something like
$("#jqGrid").setGridParam({datatype: 'local'});
And that when you reload the grid - you correct this to "JSON" on reload if you're using it - i.e.
$("#yourGridID").setGridParam({datatype: 'json'}).trigger("reloadGrid");
Lastly, ensure that you use
name: 'Date', index: 'Date', sortable:true
Where you need it.
I'm trying to implement a JqGrid with a subgrid as so...
jQuery(document).ready(function() {
jQuery("#list").jqGrid({
url: '/OrganizationalUnit/FindAll/',
datatype: 'json',
mtype: 'GET',
colNames: ['Name', 'Actions'],
colModel: [
{ name: 'Name', index: 'Name', width: 500, align: 'left' },
{ name:'act', index:'act', width:250,sortable:false}
],
subGrid : true,
subGridUrl: '/OrganizationalUnit/Organizations/',
subGridModel:
[
{ name: 'Name', index: 'Name', width: 300, align: 'left' },
{ name: 'OrganizationID', index: 'OrganizationID', width: 300, align: 'left' }
]
...
So the way JqGrid works is that when the controller method for OrganizationalUnitController.Organizations gets called, a query string of "?id=4" gets appended to the URL. M problem is that the "4" is just an arbitrary row number that JqGrid has created for the grid and doesn't provide me with an identifier for the OrganizationalUnit the I trying to retreive a subgrid for. So what I'm wondering is it there is any way that I can assign the 'name' value to the id argument?
Has anyone figured this out before?
Ok...I have figured it out.
If I add the params: ['name'] arguement to the subGridModel definition then I can get the value of the OrganizationalUnit name through the HttpContext.Request.Params collection.
Where exactely did you put the params parameter?
I am surprised that your defintion of the subGridModel actually works.
Since the manual recommends a different structure:
subGridModel : [
{
name : ['No', 'Item', 'Qty', 'Unit', 'Line Total'],
width : [55, 200, 80, 80, 80],
align : ['left','left','right','right','right'],
params: ['invdate']
}
]
