I need to populate Kendo drop-down box automatically from the following JSON:
var products=
[
{
id: 1,
title: "Item-1",
active: true
},
{
id: 2,
title: "Item-2",
active: false
}
];
So I use the following code to do this, which works fine:
$("#productList").kendoDropDownList({
dataSource: products,
dataTextField: "title",
dataValueField: "id"
});
The problem is, I want to see only items for which 'active' is true.
How to implement that with Kendo?
Sample Jsfiddle
For Filter, can only be filter on dataSoruce that why creating kendo.data.DataSource and apply filter in filter section.
filter:{fieled:"active",operator:"eq",value:true}
HTML
<div>
<input id="productList" style="width:250px"/>
</div>
Javascript
var products=
[
{
id: 1,
title: "Item-1",
active: true
},
{
id: 2,
title: "Item-2",
active: undefined
},
{
id:3,
title:"Item-3",
active:false
},
{
id:3,
title:"Item-4",
active:undefined
}
];
var dataSource=new kendo.data.DataSource({
data:products,
filter:{
logic:'or',
filters:[
{field:"active",operator:"eq",value:true},
{field:"active",operator:"eq",value:undefined}
]}
});
$("#productList").kendoDropDownList({
dataSource: dataSource,
dataTextField: "title",
dataValueField: "id"
});

I have a grid and a multiselect ,i want to filter the grid by the multiselect according to what i select ,and when i de select,the grid should be filterd accordingly,here is my grid:
$("#grid").kendoGrid({
dataSource: ds2,
height: 550,
sortable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [
{ field: "name",
title: "Name",width:"50px"},
{ field: "Description",
title: "Description", width: "80px"
},
{ field: "WindSpeed",
title: "Wind Speed", width: "40px"
},
{ field: "RPM",
title: "RPM", width: "40px"
},
{ field: "Power",
title: "Power", width: "40px"
}
]
});
the data which bind the datasource:
var ds1 = new kendo.data.DataSource({
data: rsturn_f.EventNames
});
var ds2 = new kendo.data.DataSource({
data: rsturn_f.Data
});
and here is the multi select:
$("#evnts").kendoMultiSelect({
placeholder: "Select products...",
dataTextField: "Nme",
dataValueField: "Nme",
//autoBind: false,
select: onSelect,
deselect: onDeselect,
dataSource: ds1
});
by onselect i do this:
function onSelect(e) {
ds2.filter({ field: "Description", operator: "startswith", value: e.dataItem });
}
now if i want to filter on multiple value and un filter by removing the values from multiselect i dont know what should i do,any idea?
You have to use change event of the Multiselect. You can directly use a function in the operation attribute which is passed to the dataSource filter API.
function onChange(e) {
ds2.filter({ field: "Description", value: this.value(),
operator: function(currentValue, filterValues){
if(filterValues.length===0){
return true;
}
if(filterValues.indexOf(currentValue)!==-1){
return true;
}
return false;
}
});
}
I'm working with kendo Multiselect and I would like to find a way to search in multiple fields of my data source.
Here is my actual code. but it works only for one field:
`
$scope.dataList = new kendo.data.DataSource({
data:[{id: "1",name: "Doe, John",email: "John.Doe#example.com"}],
});
$scope.customOption = {
dataSource: $scope.dataList,
dataTextField: "name",
dataValueField: "id",
filter: "contains",
itemTemplate: '<span>#=id#</span>#=name#<i> #=email#</i>',
}
`
As you see I'm also using AngularJS, I try to search for names and emails.
$("#id").kendoMultiSelect({
placeholder: "Select products...",
dataTextField: "name",
dataValueField: "id",
autoBind: false,
filtering: function (e) {
if (e.filter) {
var value = e.filter.value
var newFilter = {
filters: [
{ field: "id", operator: "contains", value: value },
{ field: "name", operator: "contains", value: value },
{ field: "email", operator: "contains", value: value }
],
logic: "or"
}
e.sender.dataSource.filter(newFilter)
e.preventDefault()
}
e.preventDefault()
},
dataSource: {
data:[
{id: "1",name: "Doe, John",email: "John.Doe#example.com"},
{id: "2",name: "sss, John",email: "sss.Doe#example.com"},
{id: "3",name: "fff, John",email: "fff.Doe#example.com"},
{id: "4",name: "ccc, John",email: "ccc.Doe#example.com"}
],
},
value: [
{id: "1",name: "Doe, John"},
]
});
Refer to API Documentation of Kendo DataSource and MultiSelect. hope it helps.
I have a requirement in which I have to show two dropdown list in the Filterable cell of kendo grid. These two dropdown lists would filter two different columns in the kendo grid.
One thought I had is having template which would be some kendo container like some panel probably, and then add two dropdowns to that container.
Is this even possible? If yes how to achieve this?
Here is my kendo grid definition.
ctrl.mainGridOptions = {
dataSource: ctrl.gridDataSource,
columns: [
{
title: 'Col1-Col2',
field: 'Col1',
width: 200,
template: kendo.template($("#col1").html()),
filterable: { cell: { template: ctrl.coonetemplate, showOperators: false } }
},
{
field: 'Col3',
width: 150,
title: 'Col3',
template: kendo.template($("#col3").html()),
filterable: { cell: { template: ctrl.colthreeTemplate, showOperators: false } }
}
]
}
Here is a mockup of what I want to achieve.
There are a few different parts to this.
First, if you want to have multiple filter controls for different pieces of data, you should define a column for each one. Then, put a template on the first column to have it display the data for two columns. Use the attributes option to set a colspan=2. Then, use the attributes option on the second columns to set style="display:none".
The second part is getting the dropdowns. I generally prefer to use the values option to accomplish this. The code below uses this for the OrderID column. The other alternative was the approach you were on, which is to use the cell template. The code below uses this on the ShipName column.
<div id="example">
<div id="grid"></div>
<script>
$(document).ready(function() {
$("#grid").kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "http://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
schema: {
model: {
fields: {
OrderID: { type: "string" },
Freight: { type: "number" },
ShipName: { type: "string" },
OrderDate: { type: "date" },
ShipCity: { type: "string" }
}
}
},
pageSize: 20,
serverPaging: true,
serverFiltering: true,
},
height: 550,
filterable: {
mode: "row"
},
pageable: true,
columns: [
{
field: "OrderID",
width: 150,
attributes: {
colspan: 2
},
values: [
{text: "10248", value: "one"},
{text:"10249", value: "two"}
],
template: '#:OrderID# (#:ShipName#)',
filterable: {
cell: {
operator: "eq",
showOperators: false
}
}
},
{
attributes: {
style: "display:none"
},
field: "ShipName",
width: 200,
title: "Ship Name",
filterable: {
cell: {
template: function(args) {
args.element.kendoDropDownList({
dataSource: args.dataSource,
dataTextField: "ShipName",
dataValueField: "ShipName",
valuePrimitive: true
});
},
operator: "eq",
showOperators: false
}
}
},
{
field: "Freight",
width: 255,
filterable: false
}]
});
});
</script>
</div>

Kendo Grid filterable cell with custom options column wise and by using this solution it also overwrites general filters settings in case specific column requirement. ASP.NET MVC C#.
columns.Bound(c => c.columnName)
.Format("{0}%")
.Filterable(ftb => ftb
.Cell(cell => cell.ShowOperators(true))
.Extra(false)
.Operators(op => op
.ForNumber(fn => fn
.Clear()
.IsEqualTo(CommonResource.GridFilter_IsEqualTo)
)
)
)
.Title("Column Name");
I am one day old into Kendo, so I believe, I'm missing the obvious.
The grid seems to get stuck when tried to filter with Enum values set. Test Link
<div id="grid"></div>
<script>
$("#grid").kendoGrid({
columns: [
{
field: "category",
values: [{text: "Beverages", value: 1 }, {text: "Food", value: 2 }],
filterable: { mode: "row", cell: { showOperators: false, operator: "eq" } }
}
],
dataSource: [{ category: 1 }, { category: 2 } ],
filterable: {mode: "row"}
});
</script>
worked it out finally, missing type was all it seems needed. Demo Link
<div id="grid"></div>
<script>
$("#grid").kendoGrid({
columns: [
{
field: "category", type: "number",
values: [{text: "Beverages", value: 1 }, {text: "Food", value: 2 }],
filterable: { mode: "row", cell: { showOperators: false, operator: "eq" } }
}
],
dataSource: [{ category: 1 }, { category: 2 } ],
filterable: {mode: "row"}
});
</script>
I am displaying Grid and using detailTemplate to expandRow. But when expand the row, I want to pass the row ID and get datasource and display another grid.
I think detailTemplate won't work in this case. How can I do this ?
Here is my Code
$(document).ready(function () {
var dataSource = new kendo.data.DataSource({
pageSize: 20,
data: [
{ id: "1", name: "Andrew", age: "30" },
{ id: "2", name: "Robert", age: "29" },
{ id: "3", name: "Frank", age: "35" }
],
autoSync: true,
schema: {
model: {
id: "id",
fields: {
id: { editable: false, nullable: true, type: "number" },
name: { editable: false },
age: {
validation: { min: 0, required: true },
editable: true,
nullable: true,
type: "number"
}
}
}
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
pageable: true,
height: 550,
editable: "inline",
columns: [
{ field: "name",title: "Name" },
{ field: "age", title: "Age", width: "180px"},
{ command: ["edit"] }
],
detailTemplate: "<div>Name: #: name #</div><div>Age: #: age #</div>"
});
});
Did you checked this demo from Kendo UI ?
http://demos.telerik.com/kendo-ui/grid/detailtemplate
Similar to your scenario, detail grid is created in detailInit function and data for detail grid is filtered for the current employee using e.data.EmployeeID
