Does anyone know how to filter a PrimeUI datatable?? i am using angular and PrimeUI, in the html i have the text field that according to it i want to filter my data table
$('#table').puidatatable({
caption: 'my tbl',
paginator: {
rows: 9
},
columns: [
{field:'name', headerText: 'name', sortable:true} ,
{field:'age', headerText: 'age', sortable:true},
{field:'id', headerText: 'ID', sortable:true}
],
datasource: myarray
,
selectionMode: 'single',
rowSelect: function(event, data) {
some code
}});
$('#messages').puigrowl();
and in my html :
<input id="basic" name="basic" type="text"/>
As of this moment, filtering is not available on PrimeUI Datatable. It's not mentioned anywhere on the page. I suggest you consider other - options.
As there is no support to filter Prime UI data table but still you can filter your data table from server side like i have implemented prime ui data table with custom search. I send one parameter from search field if that is empty i return all data if search filed contains some data i return filtered data though this i achieve the filter functionality
<!--input filed for search -->
<input type="text" name ="abc" id="input-filter" onkeypress="javascript:gridSearch();"/>
function searchToJSON(){
return JSON.stringify({
"input-filter": document.getElementById('input-filter').value,
});
}
gridSearch = function() {
var searchUrl= 'searchUrl';
$('#table').puidatatable({
lazy: true,
paginator: {
rows: 5
},
columns: [
{field:'abc', headerText: 'abc', sortable:true},
{field:'xyz', headerText: 'xyz', sortable:true}
],
datasource: function(callback) {
$.ajax({
type: "POST",
url: searchUrl,
datatype : "application/json",
contentType: "application/json",
data:searchToJSON(), // supply json fields and return filtered data from server accoring to your requirements
context: this,
success: function(response) {
callback.call(this, response.data);
}
});
} ,
});
};

I'm trying to populate a kendo grid with data retrieved via ajax. Here is the ajax:
var model = #Html.Raw(Json.Serialize(Model));
$(document).ready(function () {
$.ajax({
url: "/Utilities/Report/Run",
data: JSON.stringify(model),
contentType: "application/json",
type: "POST",
success: function(result) {
var ds = new kendo.data.DataSource({
data: result
});
alert(result);
$("#grid").data("kendoGrid").setDataSource(ds);
},
error: function(result) {
options.error(result);
}
});
$("#grid").kendoGrid({
toolbar: ["excel", "pdf"],
excel: {
fileName: "test"
},
pdf: {
fileName: "test"
},
});
});
At the alert(result) this is what the data looks like:
[
{"TEST":"one"},
{"TEST":"two"},
{"TEST":"three"}
]
The ajax call appears to be working and the data looks good to me, but the kendo grid is not updating, it remains blank. I also do not get any error. I've tried placing the kendoGrid inside the ajax success function with the same result. I've tried using transport and read in the DataSource to retrieve the data but that kept giving me an error: n.slice is not a function. However, others seemed to think that was because there was no schema defined. Due to the kind of data I am retrieving, I cannot define this. The data retrieved from the server could have any column/field names, and any number of columns. It is not complex JSON however.
How do I get my grid to populate with this data?
I have created a new Datasource and mapped it to the existing one outside the success method.
Can you try this one below :
var newDataSource = new kendo.data.DataSource({
transport: {
read: {
url: "/Utilities/Report/Run",
dataType: "json",
data: JSON.stringify(model),
error: function (result) {
options.error(result);
}
}
}
});
var d1 = $("#grid").data("kendoGrid");
d1.dataSource.data([]);
d1.setDataSource(newDataSource );
make changes as per your necessity if I have missed any . Kendo data binding is always confusing :D
Kendo DataSource is very powerful. Ideally, you do not need to make a manual Ajax call. Instead, DataSource can Ajax request data from URL by itself, if Grid needs data.
https://jsfiddle.net/6gxqsrzu/
$(function() {
var dataSource = new kendo.data.DataSource({
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
schema: {
model: {
fields: {
OrderID: {
type: "number"
},
Freight: {
type: "number"
},
ShipName: {
type: "string"
},
OrderDate: {
type: "date"
},
ShipCity: {
type: "string"
}
}
}
},
serverPaging: true,
pageSize: 5,
serverSorting: true,
sort: {
field: 'OrderDate',
dir: 'asc'
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
sortable: true,
pageable: true,
columns: [{
field: "OrderID",
filterable: false
},
"Freight", {
field: "OrderDate",
title: "Order Date",
format: "{0:MM/dd/yyyy}"
}, {
field: "ShipName",
title: "Ship Name"
}, {
field: "ShipCity",
title: "Ship City"
}
]
});
});

I have a kendo Grid with no columns definition because grid's fields are dynamics and I don't have any chance to know the fields before databound event.
Example:
var dataSource = new kendo.data.DataSource({
type: "aspnetmvc-ajax",
transport: {
read: {
url: appPath + "Controller/GetGridData",
dataType: "json",
type: "POST",
data: {
dataSourceID: dataSourceId
}
},
},
schema: { data: "data", total: "total"},
pageSize: 10,
serverSorting: true,
serverPaging: true,
serverFiltering: true,
});
$("#grid").kendoGrid({
dataSource: dataSource,
filterable: {
extra: false
},
dataBound: function (data) {
},
pageable: {
pageSizes: true,
pageSizes: [10, 20, 50, 100]
}
)}
Is there a way to modify columns headers dynamically on databound event or after data are loaded but before showing it to users?
I achieved "dynamic" column headers (after many infuriating troubleshooting messages back and forth by Telerik) by requesting the data prior to initialising the grid via an AJAX call then determining the column names based on the data.
$.ajax({
type: "POST",
url: "/Controller/GetGridData",
// *Important* stringify the server-bound object
data: JSON.stringify(dataSourceId),
dataType: "json",
contentType: "application/json",
async: true,
success: function(response) {
// response contains data required for grid datasource
ConstructGrid(response);
}
});
function ConstructGrid(gridData) {
var dataSource = new kendo.data.DataSource({
... attributes
data: gridData,
... more attributes
});
var columnsArray = [];
if(gridData.attributeToCheck = "someValue") {
columnsArray.push({field: attributeEqualToSomeValue, title="attributeMatchingSomeValue"});
}
else {
columnsArray.push({field: attributeNotEqualToSomeValue, title="attributeNotMatchingSomeValue"});
}
.. continue to add more columns based on data then initialise grid
$("#grid").kendoGrid({
dataSource: dataSource,
filterable: {
extra: false
},
columns: columnsArray,
pageable: {
pageSizes: true,
pageSizes: [10, 20, 50, 100]
}
)};
}
Not exactly 100% dynamic but it will change the column names based on the values retrieved from the AJAX call and AFAIK (after chatting back and forth with Telerik), truly dynamic columns are not supported by the grid control.
Check this Jsbin
`https://output.jsbin.com/lesoxes/`
In this example i have used kendo's datasource.
you will get all column details in console.

I am trying to get jsGrid working in a project but I am missing something since I can't make it to work correctly. I have read docs carefully several times.
The scenario is as follow:
An AJAX call for get a list of subregion
An AJAX call for get a list of countries (each time I click on pagination a new request should be made in order to get proper values)
From docs under controller section:
loadData is a function returning an array of data or jQuery promise
that will be resolved with an array of data (when pageLoading is true
instead of object the structure { data: [items], itemsCount: [total
items count] } should be returned). Accepts filter parameter including
current filter options and paging parameters when pageLoading is true.
So my PHP function return data in the "proper" format as expected, meaning:
{
data: [items],
itemsCount: [total items count]
}
I have created a Pastebin with the result I get when the AJAX call is made (for the countries result). I believe the data is right now. So, this is how my code looks like:
$(function () {
$.ajax({
type: "GET",
url: "/adminconsolejsgrid/subregion"
}).done(function (subregion) {
$("#jsGrid").jsGrid({
height: "70%",
width: "100%",
filtering: true,
sorting: true,
paging: true,
autoload: true,
pageSize: 15,
pageButtonCount: 5,
pageLoading: true,
controller: {
loadData: function (filter) {
return $.ajax({
type: "GET",
url: "/adminconsolejsgrid/countries",
data: filter
});
}
},
fields: [
{name: "country_name", title: "Name", type: "text", width: 100, sorting: true},
{name: "country_abbr", title: "Code", type: "text", width: 5, sorting: true},
{
name: "subregion",
title: "SubRegion",
type: "select",
width: 100,
items: subregion,
valueField: "subregion_id",
textField: "subregion_name"
},
{type: "control"}
]
});
});
});
But still not working for me which mean I am not getting any values on the grid. This pic is an example of what I get:
What I am missing? Any help?
I am new to ExtJS.
I am developing a page which has a form at the top and a grid below. When user enters the search criteria in the form and enters Submit, grid has to be populated with data accordingly.
I have managed to get the JSON data from server to the client
console.log('response.responseText');
prints the data correctly, but unable to assign that to the grid.
Here is my code
Ext.define('colModel', {
extend: 'Ext.data.ColumnModel',
fields: [
'personId',
'country',
'idType',
'idValue'
]
});
// create the data store
var store = Ext.create('Ext.data.ArrayStore', {
model: 'colModel',
fields: [
{name: 'personId'},
{name: 'country'},
{name: 'idType'},
{name: 'idValue'}
],
proxy: {
type: 'ajax',
reader: {
type: 'json',
root: 'person'
}
},
autoLoad: false,
});
// create the Grid
var grid = Ext.create('Ext.grid.Panel', {
store: store,
stateful: true,
id: 'myGrid',
stateId: 'stateGrid',
columns: [
{
text : 'Person Id',
flex : 1,
sortable : false,
dataIndex: 'personId'
},
{
text : 'Country',
width : 75,
sortable : true,
dataIndex: 'country'
},
{
text : 'ID Type',
width : 75,
sortable : true,
dataIndex: 'idType'
},
{
text : 'Id Value',
width : 75,
sortable : true,
dataIndex: 'idValue'
},
],
height: 350,
title: 'Array Grid',
renderTo: 'bottom',
viewConfig: {
stripeRows: true,
ForceFit: true,
loadMask:false
}
});
and this function get invoked after form submission and response returned from server
displayGrid : function(response, opts) {
//Received response from the server
console.log('On Success');
responseData = Ext.decode(response.responseText);
console.log('response success ',responseData);
console.log(Ext.getCmp('myGrid').getStore());
grid.getStore().loadData('colModel',false);
}
I have managed to populate grid data on page load using the following code
var store = Ext.create('Ext.data.ArrayStore', {
model: 'colModel',
proxy: {
type: 'rest',
url : 'PersonSearch',
reader: {
type: 'json',
root: 'person'
}
},
autoLoad: true
});
but failed to load grid data on form submission.
Please help. Thanks in advance.
PS: I am using ExtJS 4.2
Update
This is the JSON update, I am getting from the server(caught using Firefox Browser Console)
"{"person":[{"personId":"1","country":"country 1","idType":"idType 1","idValue":"idValue 1"},{"personId":"2","country":"country 2","idType":"idType 2","idValue":"idValue 2"},{"personId":"3","country":"country 3","idType":"idType 3","idValue":"idValue 3"},{"personId":"4","country":"country 4","idType":"idType 4","idValue":"idValue 4"},{"personId":"5","country":"country 5","idType":"idType 5","idValue":"idValue 5"}]}
"
You aren't actually loading the data. Your data is stored in responseData, so your loadData call should load that data into the store. So, your loadData call should be as follows:
grid.getStore().loadData(responseData);
Note that this assumes that your responseData is in the correct format for the store you are loading it into. (Also note that the second parameter is false by default, so it isn't necessary to include it in this case)
Used forgivenson comment and set autoLoad: true
and
Updated the displayGrid method as below
displayGrid : function(response, opts) {
//Received response from the server
console.log('On Success');
responseData = Ext.decode(response.responseText,false);
console.log(response.responseText);
grid.getStore().loadData(responseData.person);
}
and the grid gets populated correctly.
Grid reads data from a javascript variable.
$("#grid").kendoGrid({
dataSource: {
type: "text",
data: jsvar,
schema: {
model: {
fields: {
id: {type: "string", editable: false},
name: {type: "string"}
}
}
},
pageSize: 20
},
pageable: {
input: true,
numeric: true
},
//toolbar: [{text: "Add"}],
columns: [
{command: [{text: "Edit", click: showDetailse}, {text: "View", click: viewoneitm}], title: " ", width: "170px"},
]
});
Then I change value of this variable jsvar with ajax and wait for ajax response and after that when I refresh grid with
jQuery("#grid").data("kendoGrid").dataSource.read();
jQuery("#grid").data("kendoGrid").refresh();
The grid is not repopulated with new data and old data stays in grid. Please tell me how to refresh grid data.
This worked fine and grid used to refresh perfectly untill I proviced static data, but after I used ajax and then 'refresh' it failed to update
If jsvar contains an array, the Kendo data source will create a model for each array item, so if you modify the original array, it won't change the DataSource. If you want to change the data, you should do it like this:
grid.dataSource.data(jsvar);
