For my project, I set the ros parameter as follows:
std::vector<int> odomConfig;
ros::param::param("odom0_config", odomConfig, {false, false, false, false,
false, false, true, true, true, false, false, false, false, false, false});
This ros parameter is basically used by ekf_localization_node of robot_localization package.
However, an error is thrown from this line of code.
Where am I doing wrong in setting the ros parameter ?

When using kendo.data.extensions.BreezeDataSource, this error appears :
The 'query' parameter must be an instance of 'EntityQuery', or it must be a 'string'
This is my code :
var dataSource = new kendo.data.extensions.BreezeDataSource({
entityManager: manager,
endPoint: "Clients",
serverSorting: true,
serverPaging: true,
serverFiltering: true,
pageSize: 10
});
Please advise.
I have an object that contains the following filter string:
prefs.filters={"groupOp":"AND","rules":[{"field":"FirstName","op":"cn","data":"max"}]}
Here is my grid create, where I am trying to apply the filters in the postData setting:
// Set up the jquery grid
$("#jqGridTable").jqGrid(
{
// Ajax related configurations
url: jqDataUrl,
datatype: "json",
mtype: "GET",
autowidth: true,
// Configure the columns
colModel: columnModels,
// Grid total width and height
height: "100%",
// customize jqgrid post init
gridComplete: function()
{
CRef.updateJqGridPagerIcons("jqGridTable");
},
// Paging
toppager: true,
rowNum: 20,
rowList: [5, 10, 20, 50, 100],
viewrecords: true, // Specify if "total number of records" is displayed
// Default sorting
sortname: typeof prefs.sortCol !== "undefined" ? prefs.sortCol : "LastName",
sortorder: typeof prefs.sortCol !== "undefined" ? prefs.sortOrd : "asc",
sorttype: "text",
sortable: true,
postData: typeof prefs.filters !== "undefined" ? { filters: prefs.filters } : {},
//also tried this...
//postData: typeof prefs.filters !== "undefined" ? { JSON.stringify(filters: prefs.filters) } : {},
//remaining property settings excluded from post to keep short.
Update: Using .navGrid on grid as follows:
.navGrid("#jqGridTable",
{ refresh: true, add: false, edit: false, del: false, refreshtitle: getRefreshText('#Model.Instruction'), searchtitle: searchText },
{}, // settings for edit
{}, // settings for add
{}, // settings for delete
{ closeAfterSearch: true, closeOnEscape: true, multipleSearch: true, multipleGroup: true });
When grid is created, the filter in postData is not applied. I also tried triggering reload event after the initial create and that to did not apply filter either.
From other posts, I believe I'm on correct path, but appear to be missing something.
Update after comments:
I added the following code to loadComplete...
if ($("#jqGridTable").jqGrid("getGridParam", "datatype") === "json") {
setTimeout(function () {
$("#jqGridTable").jqGrid("setGridParam", {
datatype: "local",
postData: { filters: prefs.filters, sord: prefs.sortOrd, sidx: prefs.sortCol },
search: true
});
$("#jqGridTable").trigger("reloadGrid");
}, 50);
}
and it successfully retains the filters. :)
However, now I have interesting issue side effect. I can sort on columns and some columns will change to sort asc/desc correctly, but when I go to others and sort, they sort but in the order that they originally loaded which is neither asc or desc.
You have to set search: true option of jqGrid if you want that filters will be applied. Moreover you use datatype: "json". It means that the filters will be just send to the server and your server code have to decode the filters and to use there. One more remark. The correct value for postData would be { filters: JSON.stringify(prefs.filters) }.
UPDATED: I recommend you upgrade to the latest version (4.12.1) or free jqGrid. It's the fork of jGrid which I develop since the end of 2014. To use free jqGrid you can just change the URLs to jqGrid files to URLs described in the wiki article. After that you can use the following options:
loadonce: true,
forceClientSorting: true,
search: true,
postData: { filters: prefs.filters },
sortname: prefs.sortCol,
sortorder: prefs.sortOrd
and remove the loadComplete code which you posted in "Update after comments" part of your question. Free jqGrid will load all data returned from the server, apply the filter prefs.filters locally, sort the results locally and display the first page of the results (based on the page size rowNum: 20).
The old demo loads the JSON data from the server, sort the data locally and filter by isFinal === 1 and finally display the first page of results. The demo uses additionally custom sorting using sortfunc, additionalProperties, which allows to saved additionally properties in local data.
You can additionally include reloadGridOptions: { fromServer: true } to other options of navGrid which you use (refresh: true, add: false, ...). It will change the behavior of the Refresh button of the navigator bar to reload the data from the server if the user clicks on the button. See another answer, which I posted today for more information about new options of free jqGrid and loadonce: true.
I just want to display the refresh button on my jqGrids. I thought it was provided naturally so I did this :
$.extend($.jgrid.nav, {
refresh: true,
refreshstate: "current"
});
but it does nothing. no button appearing.
How can I add a refresh button just triggering the reloadGrid ?
thank you
$.jgrid.nav cab be used to specify default values of navGrid parameters, but to create "refresh" button or some other button in the grid you need explicitly call navGrid method. For example
$("#gridId").jqGrid("navGrid", "#pager", {
add: false, edit: false, del: false, search: false, refresh: true
});
The method navGrid creates navigator structures in the specified pager and then places specified buttons in the navigator bar.
If you use toppager: true option then top pager will be created additionally. The pager will have id = grid_id + "_toppager" (gridId_toppager if id of the grid is gridId). You can have one or two pagers. You can call navGrid explicitly for one from the pagers or you can use cloneToTop: true option of navGrid to place the pager on every page.
If you have existing project with many grids you have sure one common JavaScript file with settings which you included on every page. You placed sure $.extend($.jgrid.nav, {...}); in the file. Whyt you can do is to specify common onInitGrid callback which calls navGrid:
$.extend($.jgrid.defaults, {
onInitGrid: function () {
var $self = $(this), p = $self.jqGrid("getGridParam");
if (p.pager) {
$self.jqGrid("navGrid", p.pager,
{add: false, edit: false, del: false, search: false, refresh: true, cloneToTop: true});
} else if (p.toppager) {
$self.jqGrid("navGrid", "#" + $.jgrid.jqID(p.id) + "_toppager",
{add: false, edit: false, del: false, search: false, refresh: true});
}
}
});
I'm trying to validate the search field for integer data alone but unfortunately am unable to do so. I have tried all possible solutions like searchrules:{required:true,integer=true} etc..
But none of them proves fruitful.
I basically launch the search dialog with the field and without inputting any data, am hitting on the 'Find' button. As per the above options, i believe a validation message should be shown to the user asking him to enter a value in the field before hitting find.
[UPDATED] - Code Snippet
var grid = $("#list");
grid.jqGrid({
url:'/index.jsp',
datatype: 'json',
mtype: 'POST',
colNames:['Name','Age', 'Address'],
colModel :[
{name:'name', index:'name', width:55,search:true },
{name:'age', index:'age',
width:90,editable:true,search:true, stype:'text',
searchrules:{required:true,integer:true}},
{name:'address', index:'address', width:80,
align:'right', editable: true,search:false }
],
pager: '#pager',
jsonReader : {
root:"address",
page: "page",
total: "total",
records: "records",
repeatitems: false
},
rowNum:10,
rowList:[10,20,30],
sortname: 'name',
sortorder: 'desc',
viewrecords: true,
gridview: true,
autowidth: true,
toppager: true,
loadtext: "Loading records.....",
caption: 'Test Grid',
gridComplete: function(){
}
});
**grid**.jqGrid('navGrid','#pager',
{view:true,edit:true,add:true,del:true,refresh:true,
refreshtext:'Refresh',addtext:'Add',
edittext:'Edit',cloneToTop:true,
edittitle: "Edit selected row"},
{},{},{},
{caption: "Search The Grid",Find: "Find Value",Reset: "Reset"},
{});
[Updated] : Am not able to make the searchrules properly work for the single/advanced searching modes.
[Updated] : Even the 'Validation in Search' in
jqGrid Demo is not working for searchrules.
The reason of described problem is a bug in jqGrid. The line
ret = $.jgrid.checkValues(val, -1, null, colModelItem.searchrules, colModelItem.label);
initialize the third parameter of $.jgrid.checkValues to null, but the last version of checkValues implementation started (see the line) with
var cm = g.p.colModel;
but g is initialized to null. The last modification which generates the error was based on my suggestion, but I don't wrote the part of the code.
One can solve the problem in different way. I would suggest to modify the line where $.jgrid.checkValues will be called with null parameter to the following
ret = $.jgrid.checkValues(val, -1, {p: {colModel: p.columns}}, colModelItem.searchrules, colModelItem.label);
Additionally, to be sure, I would suggest to modify one more line
if(!nm) { nm = g.p.colNames[valref]; }
to
if(!nm) { nm = g.p.colNames != null ? g.p.colNames[valref] : cm.label; }
The fixed version of jquery.jqGrid.src.js one can get here. I will post my bug report with the same suggestions later ti trirand.
I'm having some issues setting the url of the jqgrid using setGridParam.
I receive the message: "f is undefined".
My setup:
$("#prices").jqGrid({
colModel: [
...
],
pager: jQuery('#pricePager'),
ajaxGridOptions: { contentType: "application/json" },
mtype: 'POST',
loadonce: true,
rowTotal: 100,
rowNum: -1,
viewrecords: true,
caption: "Prices",
height: 300,
pgbuttons: false,
multiselect: true,
afterInsertRow: function (rowid, rowdata, rowelem) {
// ...
},
beforeSelectRow: function (rowid, e) {
// ...
},
onSelectRow: function (rowid, status) {
// ...
}
});
Getting the data:
$("#prices").setGridParam({ datatype: 'json', page: 1, url: '#Url.Action("GridDataPrices")', postData: JSON.stringify(selections) });
$("#prices").trigger('reloadGrid');
The Response is non encoded json:
{"total":1,"page":1,"records":100,"rows":[{"id":160602948,"StartDate":"\/Date(1311717600000)\/","Duration":7,"Price":1076.0000,"Code":"code"},{"id":160602950,...}]}
However, I get following message, using firebug:
"f is undefined"
I got this working first using addJSONData, but had to replace it because I want to preserve the local sorting.
Thanks in advance.
After you uploaded the code all will be clear. Your main errors are the follwings:
you should include datatype: 'local' in the jqGrid. Default value is 'xml'.
the JSON data have named properties so you have to use jsonReader: { repeatitems: false } (see the documentation for details)
you use "ArivalCodeWay" in colModel and "ArrivalCodeWay" in the JSON data. So you should fix the name of the corresponding jqGrid column
to decode the date from the "\/Date(1312840800000)\/" format you should include formatter:'date' in the corresponding column.
In the same way I find good to include formatter:'int', sorttype:'int' in the 'Duration' column and sorttype:'number', formatter:'number', formatoptions: { decimalPlaces:4, thousandsSeparator: "," } in the 'Price' column.
if you use JSON.stringify you should include json2.js to be sure that your code will work in all web browsers.
The modified demo (including some other minor changed) you can find here. If you click on "Click me" button the grid contain will be loaded.
