So in a current app, I have to use a custom Formatter on a couple rows in my jqGrid. All these do is take a few fields from my ajax call, concat them into one, and place that into a row.
EG ( data.toStreet + data.toCity + data.toState + data.toZip ) comes back as "Street City, State Zip" into the "To Address" column. This works fine and the data displays correctly, but when using the filtering toolbar, the filter is only based on the first val (data.street). below is a super simplified version of the pieces of code in question.
$('#grid').jqGrid({
...
colNames:["AddressTo", "AddressFrom"],
colModel:[
{name:"toStreet" formatter: ToAddressFormatter},
{name:"fromStreet" formatter: FromAddressFormatter}
],
...
}),
$('#grid').jqGrid('filterToolbar',
{
stringResult:true,
searchOnenter: true,
defaultSearch: 'cn'
}
});
ToAddressFormatter = function(el, opt, rowObj){
var address = rowObj.toStreet+ " " + rowObj.toCity + ", " + rowObj.toState + " " + rowObj.toZip;
return address;
},
FromAddressFormatter = function(el, opt, rowObj){
var address = rowObj.fromStreet+ " " + rowObj.fromCity + ", " + rowObj.fromState + " " + rowObj.fromZip;
return address;
}
So if the value in the cel says "123 fake st, springfield, Va 22344" after being formatted, the filter toolbar can only search on "123 fake st" and nothing else.
Does anybody have any clue on how to remedy this, or possibly why it's happening and a good workaround??
EDIT:
I have included the beginning of my grid. Also, the property Address of result.d is created in the code below, and not returned from the webservice. My column is mapped to "Address" which displays the formatting properly, but still does not search as intended.
$('#grdDisasters').jqGrid({
datatype: function(postdata) {
var obj = { "showActive": $('#btnFilterActive.pressed').length > 0 ? true : false, "showInactive": $('#btnFilterActive.pressed').length > 0 ? true : false,
'page': postdata.page, 'rows': postdata.rows, 'sortIndex': postdata.sidx, 'sortDirection': postdata.sord, 'search': postdata._search,
'filters': postdata.filters || ''
};
$.ajax({
url: "/GetGrid",
data: JSON.stringify(obj),
success: function(result) {
for (var i = 0, il = result.d.rows.length; i < il; i++) {
LoadedDisasters[i] = result.d.rows[i];
result.d.rows[i].cells.Address = result.d.rows[i].cells.Street + " " + result.d.rows[i].cells.City + ", "+ result.d.rows[i].cells.State+ " "+ result.d.rows[i].cells.Zip;
}
result.d = NET.format(result.d);//just correctly format dates
UpdateJQGridData($('#grdDisasters'), result.d);
},
error: function(result) {
//alert("Test failed");
}
});
jqGrid has a problem filtering rows when data is formatted using custom/predefined formatter.
You will have to filter rows on the server-side.
Add 2 more request parameter in your controller to handle jqgrid search request:
When jqGrid requests for filtered raws it will add a parameter: _search with value: true
and all the search parameter like col1=abc&col4=123 meaning user wanted to filter using column named col1 and column named col4 with values respectively: abc and 123
Use those values and query the database with like operation something as follows:
select id, concat(street1, street2, city, state, zip) as address
where address like "%abc%" and id like "%123%"
return these rows as json to jqGrid and display those in the current page. So basically you will have to have a jqGrid with server-side paging, sorting and searching. You can not use client-side paging, sorting and searching features. Also, make sure you don't have loadonce: true set.
I think that you fill the grid in the wrong way. If your source data has toStreet, toCity, toState, toZip, fromStreet, fromCity, fromState, fromZip properties and you need to have composed addressTo and addressFrom you should do this in another way. Your problem is that toStreet and fromStreet will be saved locally in the internal data parameter in the original format like you get it from the server. The local searching uses the data parameter, so the toStreet and fromStreet like you get there from the server will be used.
You don't posted more full code of jqGrid which you use. So I suppose that you use datatype: 'json', datatype: 'jsonp' or datatype: 'xml' in combination with loadonce: true. You should define colModel
$('#grid').jqGrid({
...
colNames:["AddressTo", "AddressFrom"],
colModel:[
{name: "addressTo", ...},
{name: "addressFrom", ...}
],
beforeProcessing: function (data) {
var i, rows = data.rows, l = rows.length, item;
for (i = 0; i < l; i++) {
item = rows[i];
item.addressTo = item.toStreet + " " + item.toCity + ", " +
item.toState + " " + item.toZip;
item.addressFrom = item.fromStreet+ " " + item.fromCity + ", " +
item.fromState + " " + item.fromZip;
}
}
...
});
The exact code depend on the format of the input data. The advantage of the usage of beforeProcessing is that it will be called before the data will be processed by jqGrid. So you can do any modification in the data or like in the above.
UPDATED: The code of datatype can be easy implemented in another way using standard jqGrid options. So I suggest to use the following settings:
datatype: "json",
url: "/GetGrid",
postData: {
// add and to the list of parameters sent to the web service
showActive: function () {
return $('#btnFilterActive.pressed').length > 0;
},
showInactive: function () {
return $('#btnFilterActive.pressed').length > 0;
}
},
prmNames: {
// rename some parameters sent to the web service
sort: "sortIndex",
order: "sortDirection",
search: "search",
// don't send nd parameter to the server
nd: null
// you leave the nd is you don't set any "Cache-Control" HTTP header
// I would recommend you to set "Cache-Control: private, max-age=0"
// For example
// HttpContext.Current.Response.Cache.SetMaxAge (new TimeSpan(0));
},
serializeGridData: function (postData) {
// control modification of the the data (parameters) which will be sent
// to the web method
if (typeof postData.filters === "undefined") {
postData.filters = "";
}
return JSON.stringify(postData);
},
ajaxGridOptions: { contentType: "application/json" },
jsonReader: {
root: "d.rows",
page: function (obj) { return obj.d.page; },
total: function (obj) { return obj.d.total; },
records: function (obj) { return obj.d.rows.length; },
repeatitems: false
},
loadError: function (jqXHR, textStatus, errorThrown) {
// see an implementation example in the answers
// https://stackoverflow.com/a/6969114/315935
// and
// https://stackoverflow.com/a/5501644/315935
},
colNames:["AddressTo", "AddressFrom"],
colModel:[
{name: "addressTo", ...},
{name: "addressFrom", ...}
],
beforeProcessing: function (data) {
var i, rows, l, item;
data.d = NET.format(data.d); // just correctly format dates
rows = data.d.rows;
l = rows.length;
for (i = 0; i < l; i++) {
item = rows[i];
LoadedDisasters[i] = item;
item.addressTo = item.toStreet + " " + item.toCity + ", " +
item.toState + " " + item.toZip;
item.addressFrom = item.fromStreet+ " " + item.fromCity + ", " +
item.fromState + " " + item.fromZip;
}
}
...
The usage of nd: null with setting of "Cache-Control: private, max-age=0" I described in the answer. You can download the corresponding demo project which use this. In general one needs just include one additional line where you call SetMaxAge
[WebMethod]
[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
public MyGridData GetGrid(...) {
HttpContext.Current.Response.Cache.SetMaxAge (new TimeSpan(0));
...
}
