SlickGrid filter not working - slickgrid

I am fairly new to SlickGrid. I am trying to make SlickGrid filter work but no luck. I am following the example (http://mleibman.github.io/SlickGrid/examples/example4-model.html).
Below is my source code.
$(document).ready(function() {
var tName;
$('#submit').click(function(e) {
tName = $('#source option:selected').text();// name1
tName = tName.trim();
$.ajax({
url : 'someUrl',
type : 'GET',
cache : false,
success : function(d) {
var grid;
var searchString = "";
var data = [];
var columns = new Array();
var cols = d[0].columns;
var pkColNames = d[0].pkColNames;
for (var j=0; j< cols.length; j++) {
var key = {id: cols[j].colName, name: cols[j].colName, field: cols[j].colName, width: 200, sortable:true, editor: Slick.Editors.LongText};
columns[j] = key;
}
var options = {
editable: true,
enableAddRow: false,
enableCellNavigation: true,
asyncEditorLoading: false,
enableColumnReorder:true,
multiColumnSort: false,
autoEdit: false,
autoHeight: false
};
function myFilter(item, args) {
return true;// Let us return true all time ?
}
for (var i = 0; i < d.length; i++) {
var tempData = (data[i] = {});
var title = null;
var val = null;
for (var q = 0; q < d[i].columns.length; q++) {
title = d[i].columns[q].colName;
val = d[i].columns[q].colValue;
tempData[title] = val;
}
}
var dataView = new Slick.Data.DataView({ inlineFilters: true });
grid = new Slick.Grid("#myGrid", dataView, columns, options);
dataView.setPagingOptions({
pageSize: 25
});
var pager = new Slick.Controls.Pager(dataView, grid, $("#myPager"));
var columnpicker = new Slick.Controls.ColumnPicker(columns, grid, options);
grid.setSelectionModel(new Slick.CellSelectionModel());
grid.onAddNewRow.subscribe(function(e, args) {
// Adding a new record is not yet decided.
});
grid.onCellChange.subscribe(function (e) {
var editedCellNo = arguments[1].cell;
var editedColName = grid.getColumns()[editedCellNo].field;
var newUpdatedValue= arguments[1].item[grid.getColumns()[editedCellNo].field];
var editedColType = "";
for (var cnt = 0; cnt < cols.length; cnt++) {
if (editedColName == cols[cnt].colName) {
editedColType = cols[cnt].colType;

var value = arguments[1].item[grid.getColumns()[p].field];
pkKeyValue += "{"+pkColNames[v] + '~' +getColDbType(grid.getColumns()[p].field) + ":"+value+"},";
break;
}
}
}
function getColDbType(colName) {
for (var c = 0; c < cols.length; c++) {
if (colName == cols[c].colName) {
return cols[c].colType;
}
}
}
pkKeyValue = pkKeyValue.substring(0, pkKeyValue.length-1);
$.ajax({

success: function(f) {
bootbox.alert("Data updated successfully");
},
error: function() {
bootbox.alert("Error - updating data. Please ensure you are adding the data in right format.");
grid.invalidateAllRows();
grid.render();
}
});
});
grid.onClick.subscribe(function (e) {
//do-nothing
});
dataView.onRowsChanged.subscribe(function(e, args) {
grid.updateRowCount();
grid.invalidateRows(args.rows);
grid.render();
});
grid.onSort.subscribe(function(e, args) {
// args.multiColumnSort indicates whether or not this is a multi-column sort.
// If it is, args.sortCols will have an array of {sortCol:..., sortAsc:...} objects.
// If not, the sort column and direction will be in args.sortCol & args.sortAsc.
// We'll use a simple comparer function here.
var comparer = function(a, b) {
return a[args.sortCol.field] > b[args.sortCol.field];
}
// Delegate the sorting to DataView.
// This will fire the change events and update the grid.
dataView.sort(comparer, args.sortAsc);
});
// wire up the search textbox to apply the filter to the model
$("#txtSearch").keyup(function (e) {
console.log('Called...txtSearch');
Slick.GlobalEditorLock.cancelCurrentEdit();
// clear on Esc
if (e.which == 27) {
this.value = "";
}
searchString = this.value;
updateFilter();
});
function updateFilter() {
console.log("updateFilter");
dataView.setFilterArgs({
searchString: searchString
});
dataView.refresh();
}
dataView.beginUpdate();
dataView.setItems(data, pkColNames);
dataView.setFilterArgs({
searchString: searchString
});
dataView.setFilter(myFilter);
dataView.endUpdate();
},
error : function() {
bootbox.alert("Invalid user");
}
});
});
});

Your function myFilter() is always returning true so of course it will never work. The example that you looked at, was to filter something specific. I would recommend that you look at the following example to have a generic filter. From the example, simply type the text you are looking on a chosen column and look at the result... see example below (from SlickGrid examples).Using fixed header row for quick filters
In case you want a more in depth conditional filters ( > 10, <> 10, etc...), please take a look at my previous answer on how to make this kind of filtering possible, see my previous answer below:SlickGrid column type
Hope that helps you out

Bootstrap Multiselect filtering values based on another dropdown

I'm working on cascading the multi-select based on the values of the data-attributes on another.
I have this method which is called inside the onChanged event of the parent. By parent I mean what to filter the child by i.e
Parent = Department Multiselect
Child = Staff Multiselect.
The child element has a data attribute of data-departmentid.
function cascadeMultiselect(control, targetControl, key) {
this.control = control;
this.targetControl = targetControl;
this.key = key;
this.toHide = [];
this.toShow =[];
//Get controls selectedIds
this.selectedIds = function() {
var selected = [];
_.each($(this.control + " option:selected"), function(c) {
selected.push($(c).val());
});
return selected;
};
//Now filter
this.filter = function() {
//Get target control attribute values
_.each($(targetControl + " option"), function(tc) {
//Use the val as an identifier
var val = $(tc).val();
var data = $(tc).attr("data-" + key);
data = data.split(",");
var isMatch = anyMatchInArray(data, this.selectedIds());
if(!isMatch){
$(tc).hide();
}
});
}
this.filter();
$(targetControl).multiselect('rebuild');
}
It's being called like so:
onChange: function() {
cascadeMultiselect('#departmentlist', '#stafflist', "DepartmentID");
}
The problem is I can't hide the elements. The filter works just fine, I've tried:
$(tc).hide(); // tc = targetControl option
I've also tried to refresh instead of rebuild.
Since it seems the only way to do this was to store the values of the multiselect, and then remove / add the relevant values.
I decided to use a rudimentary Cache class:
var Cache = (function () {
this.all = [];
function Cache(control) {
this.control = control;
}
Cache.prototype.getAll = function () {
return this.all;
};
Cache.prototype.setAll = function (all) {
this.all = all;
};
return Cache;
})();
Function now looks like:
function cascadeMultiselect(control, targetControl, key, cache) {
this.control = control;
this.targetControl = targetControl;
this.key = key;
this.toHide = [];
this.toShow =[];
//To reset the multiselect
this.reset = function(){
$(targetControl).html('');
$(targetControl).multiselect('dataprovider', cache.all)
}
//Get controls selectedIds
this.selectedIds = function() {
var selected = [];
_.each($(this.control + " option:selected"), function(c) {
selected.push($(c).val());
});
return selected;
};
//Now filter
this.filter = function() {
//Get target control attribute values
_.each($(targetControl + " option"), function(tc) {
//Use the val as an identifier
var val = $(tc).val();
var data = $(tc).attr("data-" + key);
data = data.split(",");
var isMatch = anyMatchInArray(data, this.selectedIds());
console.log($(tc));
if(!isMatch){
$(tc).remove();
}
});
}
//If nothing selected then reset the multiselect
if(this.selectedIds().length == 0){
this.reset();
return;
}else{
this.filter();
}
$(targetControl).multiselect('rebuild');
}
When I first populate the multiselect with the dataprovider I add the data to the cache:
if(cache != null){
cache.setAll(this.dataToAdd);
}

Json result returned as a file in Internet Explorer?

net MVC application, in which I have multiple charts. On these charts, I have applied filters and by clicking each filter, I do an ajax call which returns the result in Json and then applies to the charts.
Now its working perfectly in Firefox and Chrome, but in Internet Explorer - Ajax call is always unsuccessful. I tried hitting the web api url directly through my browser and the issue it seems is, the result json was being returned as a file to be downloaded.
This is my ajax code :
function getIssueResolvedGraphdata(control, departCode, departName) {
$.ajax(
{
type: "GET",
url: WebApiURL + "/api/home/GetQueryIssueResolvedData?deptCode=" + departCode,
dataType: "json",
crossDomain: true,
async: true,
cache: false,
success: function (myData) {
var resolvedStartDate = myData.data.IssueResolvedStartDate;
var issueData = myData.data.IssueData;
var resolveData = myData.data.ResolvedData;
//converting issueData into integer array...
var issue = issueData.replace("[", "");
var issue1 = issue.replace("]", "");
var issue2 = issue1.split(",");
for (var i = 0; i < issue2.length; i++) { issue2[i] = parseInt(issue2[i]); }
//converting resolvedData into integer array
var resolve = resolveData.replace("[", "");
var resolve1 = resolve.replace("]", "");
var resolve2 = resolve1.split(",");
for (var j = 0; j < resolve2.length; j++) { resolve2[j] = parseInt(resolve2[j]); }
//getting max value from array...
var issueMaxVal = Math.max.apply(null, issue2);
var resolveMaxVal = Math.max.apply(null, resolve2);
//Eliminating leading zeros in issue array
var removeIndex = 0;
var myDate;
var newDate;
var arrayLength;
if (issueMaxVal != 0) {
arrayLength = issue2.length;
for (var i = 0; i < arrayLength; i++) {
if (issue2[0] == 0) {
issue2.splice(0, 1);
removeIndex = i;
} else {
break;
}
}
//Getting days count of current month
var monthStart = new Date(new Date().getFullYear(), new Date().getMonth(), 1);
var monthEnd = new Date(new Date().getFullYear(), new Date().getMonth() + 1, 1);
var monthLength = (monthEnd - monthStart) / (1000 * 60 * 60 * 24);
var monthDays = 0;
if (monthLength == 28) {
monthDays = removeIndex;
}
else if (monthLength == 30) {
monthDays = removeIndex + 1;
}
else if (monthLength == 31 || monthLength == 29) {
monthDays = removeIndex + 2;
}
//matching the resultant issue array with resolve array & setting start date
var iDate = resolvedStartDate;
var tDate = '';
for (var i = 0; i < iDate.length; i++) {
if (iDate[i] == ',') {
tDate += '/';
}
else {
tDate += iDate[i];
}
}
if (removeIndex != 0) {
resolve2.splice(0, (removeIndex + 1));
var myDate = new Date(tDate);
myDate.setDate(myDate.getDate() + monthDays);
newDate = Date.UTC(myDate.getFullYear(), (myDate.getMonth() + 1), myDate.getDate());
} else {
var myDate = new Date(tDate);
newDate = Date.UTC(myDate.getFullYear(), (myDate.getMonth() + 1), myDate.getDate());
}
} else {
alert("Empty");
}
//updating chart here...
var chart = $('#performance-cart').highcharts();
chart.series[0].update({
pointStart: newDate,
data: issue2
});
chart.series[1].update({
pointStart: newDate,
data: resolve2
});
if (issueMaxVal > resolveMaxVal) {
chart.yAxis[0].setExtremes(0, issueMaxVal);
} else {
chart.yAxis[0].setExtremes(0, resolveMaxVal);
}
},
error: function (x, e) {
alert('There seems to be some problem while fetching records!');
} });}
Code from web api controller :
[HttpGet]
[CrossDomainActionFilter]
public Response<GraphIssueResolvedWrapper> GetQueryIssueResolvedData(string deptCode)
{
Response<GraphIssueResolvedWrapper> objResponse = new Response<GraphIssueResolvedWrapper>();
GraphIssueResolvedWrapper objGraphIssueResolvedWrapper = new GraphIssueResolvedWrapper();
try
{
....code.....
objResponse.isSuccess = true;
objResponse.errorDetail = string.Empty;
objResponse.data = objGraphIssueResolvedWrapper;
}
catch (Exception ex)
{
objResponse.isSuccess = false;
objResponse.errorDetail = ex.Message.ToString();
objResponse.data = null;
}
return objResponse;
}
Reponse Class :
public class Response<T>
{
public bool isSuccess { get; set; }
public string errorDetail { get; set; }
public T data { get; set; }
}
I am stuck at this for hours now. Any help will be appreciated.
I have solved my problem by using the following code : ( I guess it needed CORS support)
function isIE() {
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE");
if (msie > 0)
return true;
return false;
}
Then in document.ready function of my binding script :
$(document).ready(function () {
if (isIE())
$.support.cors = true;
});
Note : it still download Json stream as a file but now my AJAX call is successful upon each hit.
You've missed contentType: 'text/html' which is pretty important for IE7-8:
$.ajax(
{
type: "GET",
url: WebApiURL + "/api/home/GetQueryIssueResolvedData?deptCode=" + departCode,
dataType: "json",
contentType: 'text/html'
crossDomain: true,
async: true,
cache: false,
success: function (myData) {
var result = JSON.parse(myData);
///...code...
},
error: function (x, e) {
alert('There seems to be some problem while fetching records!');
}
}
);
To make it works in IE7-8 you also need to be sure that you've writing Conrent-Type Header into your response on server side. Add this line right before return statement;
response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html; charset=iso-8859-1");
And in code probably you will need to parse result in success method by using JSON.parse(myData);

Sorting array declared in Kendoui Observable

I have declared an content array in my kendoui observable but how do i sort it in the add function. Here's my code.
var cart = kendo.observable({
contents: [],
cleared: false,
contentsCount: function () {
return this.get("contents").length;
},
isEmpty: function () {
return (this.get("contents").length == 0);
},
add: function (item) {
var found = false;
this.set("cleared", false);
for (var i = 0; i < this.contents.length; i++) {
var current = this.contents[i];
if (current.item.id == item.id) {
current.set("quantity", current.get("quantity") + 1);
found = true;
break;
}
}
if (!found) {
this.contents.push({ item: item, quantity: 1 });
}
// I NEED TO SORT THE ARRAY HERE.
},
});

Adding new row to SlickGrid

I have a slickgrid using the dataview. From what I can tell, the grid's add new row event isn't called until after the first new row field's editor is complete. The field I was editing is a custom editor that uses a input box with autocomplete and save the selected item "value" to the grid source data. The problem is the new "item" source isn't created until the grid add new row event is fired. I know there is a way around this and just want to know what is the best way to solve for this.
Thanks.
//Add new row event
grid.onAddNewRow.subscribe(function (e, args) {
var item = args.item;
addnewid = addnewid - 1;
item.inventorytransferdetailid = addnewid;
$.extend(item, args.item);
dataView.addItem(item);
});
// Custom editor
function Suggest2(args) {
var $input;
var defaultValue;
var scope = this;
this.init = function () {
$input = $("<INPUT type=text class='editor-text' />")
$input.width = args.column.width;
$input.appendTo(args.container);
$input.focus();
$input.bind("keydown.nav", function (e) {
if (e.keyCode === $.ui.keyCode.LEFT || e.keyCode === $.ui.keyCode.RIGHT) {
e.stopImmediatePropagation();
}
else if ($input.val().length > 0) {
$.ajax({
type: "GET",
url: "http://localhost:11111/GetProducts/" + $input.val(),
dataType: "json",
data: "{}",
contentType: "application/json; charset=utf-8",
success: function (data) {
$input.autocomplete({
source: data,
select: function (event, ui) {
var v = ui.item.value;
var l = ui.item.label;
//Set "display" field with label
args.item[args.column.field] = l;
this.value = l;
//Set "hidden" id field with value
args.item["productid"] = v;
return false;
}
});
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
}
})
};
this.destroy = function () {
$input.remove();
};
this.focus = function () {
$input.focus();
};
this.getValue = function () {
return $input.val();
};
this.setValue = function (val) {
$input.val(val);
};
this.loadValue = function (item) {
defaultValue = item[args.column.field] || "";
$input.val(defaultValue);
$input[0].defaultValue = defaultValue;
$input.select();
};
this.serializeValue = function () {
return $input.val();
};
this.applyValue = function (item, state) {
//item[args.column.field] = state;
};
this.isValueChanged = function () {
return (!($input.val() == "" && defaultValue == null)) && ($input.val() != defaultValue);
};
this.validate = function () {
if (args.column.validator) {
var validationResults = args.column.validator($input.val());
if (!validationResults.valid) {
return validationResults;
}
}
return {
valid: true,
msg: null
};
};
this.init();
}
You can try below code.
function add_new_row(){
item = {
"id": (Math.round(Math.random()*-10000))
};
data_view.insertItem(0, item);
}
Then, bind with button.
<button onclick="add_new_row()">Add Row</button>

How to do Client side pagination for filtered data

YAHOO.util.Event.addListener("genes", "change", function(e) {
var value = YAHOO.util.Event.getTarget(e).value;
if(YAHOO.lang.isValue(value)) {
myDataTable.getDataSource().sendRequest(null, {
success:function(request, response, payload) {
this.initializeTable();
var rs = response.results;
var filtered = [];
for(var i = 0; i < rs.length; i++) {
//alert(rs[i].gene);
if(rs[i].gene == value) {
filtered[filtered.length] = rs[i];
}
}
this.getRecordSet().setRecords(filtered, 0);
this.render();
},
scope:myDataTable,
argument:null
});
}
});
This is my code to filter the data. i am getting the data perfectly when i change the option for selection.
but the pagination is not working it is showing as '0' even the records are displayed.
can any one plz suggest me.
Thanks!!
You can try this:
dobMenuButton.subscribe("selectedMenuItemChange",function(e) {
var value =e.newValue.value;
if(YAHOO.lang.isValue(value)) {
myDataTable.getDataSource().sendRequest(null, {
success:function(request, response, payload) {
this.initializeTable();
var rs = response.results;
var filtered = [];
for(var i = 0; i < rs.length; i++) {
if(((rs[i].dateOfBirth).format("MM/dd/yyyy")) == value) {
filtered[filtered.length] = rs[i];
}
}
this.getRecordSet().reset();
MCMPagination.paginatorvar.setTotalRecords(filtered.length,true);
this.getRecordSet().setRecords(filtered, 0);
this.render();
},
scope:myDataTable,
argument:myDataTable.getState()
});
}
});
