i am trying to retrieving data by custom searching. my code work properly, but when i try to filter some data from the input box. the process, get stuck. Please can anyone tell me what I m forgotting ?
My JQuery
//this work fine retrieving data by only if i search using "Search box"
var dataTableInstance = $("#dataTable").DataTable({
bServerSide: true,
sAjaxSource: 'AccountingMovementsService.asmx/GetAccountingMovements',
"processing": true,
sServerMethod: 'POST',
columns: [
{
'data': 'Payment'
},
{
'data': 'Account',
},
{
'data': 'customer',
}
]
});
//here I make all input box under footer columns (work fine)
$('#dataTable tfoot th').each(function () {
var title = $(this).text();
$(this).html("<input type='text' placeholder='" + title + "' />");
});
//And here i get stuck processing ... and data not come
dataTableInstance.columns().every(function() {
var dataTableColumn = this;
$(this.footer()).find('input').on('keyup change', function () {
dataTableColumn.search(this.value).draw();
});
});
If i use NOT SERVER-SIDE all work fine
My c# code is
[WebMethod]
public void GetAccountingMovements(int iDisplayLength, int iDisplayStart, int iSortCol_0, string sSortDir_0, string sSearch)
{
int displayLength = iDisplayLength;
int displayStart = iDisplayStart;
int sortCol = iSortCol_0;
string sortDir = sSortDir_0;
string search = sSearch;
int filteredCount = 0;
var accountingTransactions = new List<AccountMovement>();
string cs = ConfigurationManager.ConnectionStrings["Sg4DevMaster"].ConnectionString;
using (SqlConnection conn = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand("spGetAccountingTransactions", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter
{
ParameterName = "DisplayLength",
Value = displayLength
});
cmd.Parameters.Add(new SqlParameter
{
ParameterName = "DisplayStart",
Value = displayStart
});
cmd.Parameters.Add(new SqlParameter
{
ParameterName = "SortCol",
Value = sortCol
});
cmd.Parameters.Add(new SqlParameter
{
ParameterName = "SortDir",
Value = sortDir
});
cmd.Parameters.Add(new SqlParameter
{
ParameterName = "Search",
Value = search
});
conn.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
AccountMovement am = new AccountMovement();
filteredCount = Convert.ToInt32(rdr["totalCount"]);
am.payment = Convert.ToDouble(rdr["payment"]);
am.Account = Convert.ToDouble(rdr["account"]);
am.Customer = rdr["Customer"].ToString();
accountingTransactions.Add(am);
}
}
var result = new
{
iTotalRecords = GetAccountingMovementsTotalCount(),
iTotalDisplayRecords = filteredCount,
aaData = accountingTransactions
};
JavaScriptSerializer js = new JavaScriptSerializer();
Context.Response.Write(js.Serialize(result));
}
All work fine using "the main search input box" in the DataTable Plugin, but it get stuck when put some data in one of custom input box placed in the footer
Thank for you time!
If you go to my GitHub https://github.com/bindrid/DataTablesServerSide take a look at the c# classes. That is how I take the parameters provided by DataTable and turn it into a usable c# object.
Also listed there is my web method that uses those classes.
Below is the DataTables logic, including your search stuff and it all works.
var table = $('#example').DataTable({
"processing": true,
"serverSide": true,
"rowCallback": function (row, data) {
if ($.inArray(data.employeeId, selected) !== -1) {
table.row(row).select();
}
},
"infoCallback": function (settings, start, end, max, total, pre) {
var api = this.api();
var pageInfo = api.page.info();
return 'Page '+ (pageInfo.page+1) +' of '+ pageInfo.pages + " ";
},
rowId:"employeeId",
"createdRow": function (row, data, dataIndex) {},
"columns": [
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "extn" },
{ "data": "start_date" },
{ "data": "salary" }
],
"select":"multi",
"lengthMenu": [5, [10, 15, 25, 50, -1], [5, 10, 15, 25, 50, "All"]],
"pageLength": 5,
"ajax": {
contentType: "application/json; charset=utf-8",
url: "wsSample.asmx/GetDTDataUnserializedObject",
type: "Post",
data: function (dtParms) {
// notice dtParameters exactly matches the web service
return JSON.stringify({ dtParameters: dtParms });
},
// Data filter is a part of ajax and lets you look at the raw
dataFilter: function (res) {
// You probably know by know that WebServices
// puts your data in an object call d. these two lines puts it
// in the form that DataTable expects
var parsed = JSON.parse(res);
return JSON.stringify(parsed.d);
},
error: function (x, y) {
debugger;
console.log(x);
}
},
order: [[0, 'asc']]
});
// add search boxes to footer
$('#example tfoot th').each(function () {
var title = $(this).text();
$(this).html("<input type='search' placeholder='" + title + "' />");
});
//And here i get stuck processing ... and data not come
table.columns().every(function () {
var dataTableColumn = this;
$(this.footer()).find('input').on('keyup change', function () {
dataTableColumn.search(this.value).draw();
});
});

All I am trying to do is that I want to refresh my DataTable when the page is relaoded/refreshed. Right now on refreshing the page it retains its data. My application is using ASP.Net MVC tech.
Here is my Data Table and relevant functions:
$(document).ready(function () {
//debugger;

table.on('draw', function () {
var widthofPagination = $('.dataTables_paginate.paging_simple_numbers').width() + 25;
$('#user_session_center_grid_info').css({ width: 'calc(100% - ' + widthofPagination + 'px)' });

});
Here are my controller functions:
public ActionResult UserSessionCenter()
{
if (Session["selectedCustomer"] == null)
{
Session["selectedCustomer"] = 9;
}
int customerId = (int)Session["selectedCustomer"];
var model = new UserSessionHistory();
var daccess = new ApplicationCommon.Ado.SqlDataAccess();
var customerNamesDt = daccess.GetUserNames(customerId);
var customerList = new List<UserSessionData>();

customerList.Add(userinfo);
}
model.UserInfoList = customerList;
return View(model);
}
[HttpPost]
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public JsonResult GetUserSessionHistory()
{
var draw = Request.Form.GetValues("draw").FirstOrDefault();
var start = Request.Form.GetValues("start").FirstOrDefault();
var length = Request.Form.GetValues("length").FirstOrDefault();
if (Request["value1"] != null)
Session["userId"] = Request["value1"];
int pageSize = length != null ? Convert.ToInt32(length) : 0;
try
{
var UserID = Convert.ToInt32(Session["userId"]);
var filterModel = new FilterSessionHistoryModel();
filterModel.UserID = UserID;
filterModel.Skip = int.Parse(start);
filterModel.Take = int.Parse(length);
var fromDate = Request["FromDate"];
var toDate = Request["ToDate"];
filterModel.userSearch = Request["userSearch"];
if (!string.IsNullOrEmpty(fromDate) && !string.IsNullOrEmpty(toDate))
{
filterModel.DateFrom = fromDate;
filterModel.DateTo = toDate;
}
UserService userService = new UserService();
List<ADM_User_Session_History_Result> SessionList = userService.ADM_User_Session_History(filterModel);
int? numberOfRecords = 0;
if(SessionList.Count>0) {
numberOfRecords=SessionList[0].NumberOfRecords;
}
return Json(new { draw = draw, recordsFiltered = (int)numberOfRecords, recordsTotal = (int)numberOfRecords, data = SessionList }, JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
CustomLogging.LogMessage(ex.Message + "/r/n" + ex.Source + "/r/n" + ex.StackTrace, LogType.Error);
return this.GetJSONObject(false, ex.Message.ToString());
}
}
The hierarchy is like this.
1. The Admin user can use any customer
2. One customer can have many users
3. The table shows the time of log in of the user selected.
The problem is that the list through which the Admin can change the Customer is in the top nav present in _Layout.cshtml where as this data table is in another view. The data changes fine while cahanging the user but I need it to reload or get empty when the customer is changed.
old browsers like 'explorer' keep caching the info from a first ajax call,
you can try to set the cash flag to false and the table will be updated each time
function ReLoadTable() {
$.ajax({
cache: false,
url: 'Your URL',
type: 'POST',
in controller put this attribute
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public class HomeController : Controller
{
finally in your Global.asax file add this function
protected void Application_PreSendRequestHeaders(Object sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(false);
}
Hi I'm having some major issues trying to understand how to datatables to work with server side processing. For some background I'm using a service call Gamesparks to create the backend for a videogame and inside this service they have an implementation of mongodb.
I have an endpoint that fetchs all my users and I can see them in my table but the issue is that I fetch all of them, how can I achieve a pagination?. In the documentation they state that we must put serverSide to true but is not working. I really have no idea on how to proceed I need help.
Gamesparks event to fetch all users
require("LeaderboardMethods");
var playerList = Spark.runtimeCollection("playerList").find({},{"_id":0});
var finalData = [];
while(playerList.hasNext()){
var current = playerList.next();
var playerStats = Spark.runtimeCollection("playerStatistics").findOne({
"playerId":current.playerId
});
var loadedPlayer = Spark.loadPlayer(current.playerId);
var score = getScore(current.playerId);
if(loadedPlayer === null){
var toReturn = {
"playerId": current.playerId,
"displayName": current.displayName,
"email": "DELETED",
"rank": current.rank,
"coins": "DELETED",
"ban": "DELETED",
"score": score
}
finalData.push(toReturn);
} else{
var coins = loadedPlayer.getBalance("COIN");
var toReturn = {

Quick peek into Gamesparks SDK and found this for example:
ListTransactionsRequest
dateFrom Optional date constraint to list transactions from
dateTo Optional date constraint to list transactions to
entryCount The number of items to return in a page (default=50)
include An optional filter that limits the transaction types returned
offset The offset (page number) to start from (default=0)
Now, for paging you need entryCount and offset. First is size of one page, default 50, you can change it. Server returns 'entryCount' no of records.
Offset is the starting record. For example, initial list (1st page) does have 50 records, clicking "Next" button will send request "offset: 51" to the server. And server reply records from 50 (offset) to 100 (offset + entryCount).
var bodyData = {
"#class": ".LogEventRequest",
"eventKey": "GET_PLAYER_DATA",
"playerId": "MY_ID",
"entryCount": entryCount, // you have to send it if you dont like the default value
"offset": offset // gets his value from "NEXT" or "PREV" button
}
Thats how paging works. I'm not able to give more detailed answer as I dont use Gamesparks myself. Hope it gives you least some directon.
Ok, here are the Versions:
Kendo UI v2014.3.1119
AngularJS v1.3.6
jQuery v#1.8.1 jquery.com
The issue is the following: I have a kendo upload that should populate a grid after a excel file is read. I'm using Kendo UI Angular Directives. Here are some key pieces of code:
Upload Html
<input name="files"
type="file"
kendo-upload
k-async="{ saveUrl: '{{dialogOptions.ImportUrl}}', autoUpload: false, batch: true }"
k-options="{localization: {uploadSelectedFiles: '{{messages.Global_Button_Import}}'}}"
k-error="onImportError"
k-select="onSelect"
k-success="onImportSuccess" k-multiple="false" />
Grid Html
<div kendo-grid="grid" k-options="gridOptions" k-ng-delay="gridOptions" k-rebind="gridOptions" >
</div>
Key pieces on the controller
angular.module('global').controller('ImportResultsController', [
'$scope', 'BaseApi', 'ImportResultsService', 'GridUtil', '$http', '$q', '$timeout',
function ($scope, BaseApi, ImportResultsService, GridUtil, $http, $q, $timeout) {
$scope.gridOptions;
$scope.gridColumns;
$scope.results = new kendo.data.ObservableArray([]);
//These columns should come from the server, right now are harcoded
$scope.getGridColumns = function () {
$scope.gridColumns = [
{ field: "Zone", width: 70, title: "Zone", template: "" },
{ field: "Aisle", width: 70, title: "Aisle", template: "" },
{ field: "Rack", width: 70, title: "Rack", template: "" },
{ field: "Shelf", width: 70, title: "Shelf", template: "" },
{ field: "Bin", width: 70, title: "Bin", template: "" },
//{ field: "DateEffectiveFrom", width: 70, title: "Date" },
{ field: "BinStatus", width: 70, title: "BinStatus", template: "" }
];
}
$scope.getClientGridOptions = function(columns, data, pageSize) {
var gridOptions = {
sortable: true,
dataSource: {
data: data,
pageSize: pageSize
},
selectable: 'row',
columns: columns,
pageable: {
pageSize: pageSize,
refresh: false,
pageSizes: [10, 20, 30],
messages: $.kendoMessages
},
};
return gridOptions
}
$scope.onImportSuccess = function (e) {
var files = e.files;
if (e.operation == "upload") {
console.log(files);
if (e.XMLHttpRequest.response != "") {
var model = $.parseJSON(e.XMLHttpRequest.response); //This step does not fail, model return is always filled
$scope.results = new kendo.data.ObservableArray([]);
for (var i = 0; i < model.Data.length; i++) {
$scope.results.push(model.Data[i]);
}
$scope.gridOptions = $scope.getClientGridOptions($scope.gridColumns, $scope.results, 10);
//$scope.grid.dataSource.data($scope.results); //This does not work
$scope.isDataReady = true;
// $("#grid").data("kendoGrid").dataSource.data($scope.results) //This does not work
// $scope.grid.refresh(); //This does not work
$scope.$apply()
}
}
}
}]);
The issues vary. Sometimes I get the data bound until the second uploaded file, and after the third time, I start receiving 'Cannot read property 'get' of undefined ' errors. When this second error happens, the bind works, but the error is present. Do you have any idea of what could it be?
In case of you need the url for the upload, here's the method. Is an MVC .net application. Since I always get the response correctly and it's a Json Array, I believe there's no issue there, but here's anyways.
dialogOptions.ImportUrl = LoadImportedBinLocations

//var y = 5 / divisor;

foreach (var file in files)

I have been reading ALL of the documentation on this and I still cannot get it to work.
I have a Web API which provides a JSON object. It's a list of 22 things. Just 22 lines of text.
I want to take these and form a TreeView. Each of these 22 strings will have items under them but I just want to get the first part working.
My first question is, how do I extract data from an API and populate a treeView with it?
On my main page, I have this:
<div id="treeView"></div>
On my JavaScript file I have this:
$("#treeView").kendoTreeView({
checkboxes: true,
dataSource: {
transport: {
read: {
url: "http://...",
dataType: "json"
}
}
}
});
When I try to run the page, I get "Request failed." [Retry]
If I open up a browser and go to this URL, data is returned fine as a JSON object.
What am I doing wrong here?
EDIT -
Code that is returning the JSON:
public List<string> getNotificationByUser(int id)
{
List<string> notificationTitles = new List<string>();
foreach (var notification in notifications)
{
notificationTitles.Add(notification.ToString());
}
return notificationTitles;
}
Ok! I've been able to reproduce your error. The question is that 22 lines of text are not a valid JSON.
Returning something like:
This
is
a
test
Is not a valid JSON.
But a valid JSON is not enough, you should return something like this:
[
{ "text": "This" },
{ "text": "is" },
{ "text": "a" },
{ "text": "test" }
]
I.e.: The result should be an array of objects where each object has a text field.
NOTE I know that it does not have to be called text but for simplicity I used it since it is the default value.
I figured out all of my answers:
function CreateNotificationTree(userId)

function treeviewSelect(e)
{
var node = this.dataItem(e.node);
window.open(node.NotificationLink, "_self");
}
}

Im new to YUI3; Im trying to poll a datasource every 10 seconds to refresh a datatable. But with the code below it says there is 'No Data To Display'... Sorry for the large amount of code...
YUI().use("datatable", "datasource-get", "datasource-jsonschema", "datatable-datasource", "datasource-polling", "datasource-function", function (Y) {
var url = "http://query.yahooapis.com/v1/public/yql?format=json" +
"&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys",
query = "&q=" + encodeURIComponent(
'select * from local.search ' +
'where zip = "94089" and query = "pizza"'),
dataSource,
table;
dataSource = new Y.DataSource.Get({ source: url });
dataSource.plug(Y.Plugin.DataSourceJSONSchema, {
schema: {
resultListLocator: "query.results.Result",
resultFields: [
"Title",
"Phone",
{
key: "Rating",
locator: "Rating.AverageRating",
parser: function (val) {
// YQL is returning "NaN" for unrated restaurants
return isNaN(val) ? -1 : +val;
}
}
]
}
});
intervalId = dataSource.setInterval(10000, {
request : query,
callback: {
success: function (e) {
table.datasource.load(e.response);
},
failure: function (e) {
}
}
});
table = new Y.DataTable({
columns: [
"Title",
"Phone",
{
key: "Rating",
formatter: function (o) {
if (o.value === -1) {
o.value = '(none)';
}
}
}
],
summary: "Pizza places near 98089",
caption: "Table with JSON data from YQL"
});
table.plug(Y.Plugin.DataTableDataSource, { datasource: dataSource });
// This line works (but it doesnt poll)
//table.datasource.load({ request: query });
table.render("#pizza");
});
The line I am not sure about is...
success: function (e) {
table.datasource.load(e.response);
},
