In the kendoGrid, you can implement the Filter Multi Checkboxes in order of specify multiple values for a single column filter.
I would like to replicate the same feature inside the kendoFilter widget. I've tried to use a kendoMultiSelect as an editorTemplate (see this Dojo example)
$(document).ready(function () {
var dataSource = new kendo.data.DataSource({
pageSize: 20,
data: products,
autoSync: true,
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: { validation: { required: true } }
}
}
}
});
$("#filter").kendoFilter({
dataSource: dataSource,
applyButton: true,
fields: [
{ name: "ProductName", label: "Product Name", editorTemplate: productDropDownEditor },
],
expression: {
logic: "and",
filters: [
{ field: "ProductName", value: "", operator: "eq" }
]
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
pageable: true,
height: 550,
columns: [
{ field: "ProductName", title: "Product Name" },
{ field: "UnitsInStock", title: "Units In Stock", width: "130px" }
]
});
});
function productDropDownEditor(container, options) {
$('<input data-bind="value: value" name="' + options.field + '"/>')
.appendTo(container)
//.kendoDropDownList({
.kendoMultiSelect({
dataTextField: "ProductName",
dataValueField: "ProductName",
autoclose: false,
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Products"
}
}
});
}
Unfortunately, I think it doesn't work because the filter.value doesn't expect an array as a parameter. Is there a standard way to use the tell the kendoFilter how to create a filter based on multiple values?
I think I see what you are trying to do. Unfortunately, you can't use it that way because kendoFilter does it one by one (i.e. you'll need to click on the "+" icon in order to add another filter). Here is another alternative of what I think you are trying to do.
First off, I'd hide kendoFilter. Then based on the multiselected product name I'd redo the expression of the filter. This still accomplishes what you are trying to do (filtering through multiselect). Try the code below in the DOJO.

i am trying to expand row on select and collapse same row on click by using Kendo Grid for Mvc UI ,, How to Check the CSS class of the arrow icon in the selected row - k-plus status ,, in the other words i would like to check if selected row is expanded or not.
Use this script:
selectable: true,
change: function() {
let $row = this.select();
if ($row.length && $row.find('[aria-expanded="true"]').length) {
this.collapseRow($row);
}
else {
this.expandRow($row);
}
}
It checks if the row is expanded by looking after an element with aria-expanded.

Is it possible to add a column to the kendo ui grid by clicking on a buutton? I have tried to add it but this column doesn't initialased in the grid and I have no any data from it. How to add a col to schema dynamically? Mabye I should somehow reinitialize it?
I want to add empty column only with the header and its name and column.field name, than to edit it in other rows. I never know beforehand what columns it will be and how much. They should be dynamic. And after adding the col new row should be with it.
The most problem is to add field to grid.dataSource.schema.model.fields.
let gridProducts = $('#gridProducts').kendoGrid({
dataSource: new kendo.data.DataSource({
data: e.event.products,
autoSync: true,
schema: {
model: {
id: "productID",
fields: {
productName: {
defaultValue: productDefault.products[0].productName,
validation: {
required: true
},
type: "string"
},
productCategory: {
defaultValue: productDefault.products[0].productCategory
},
productDiscount: {
defaultValue: productDefault.products[0].productDiscount,
type: "array"
}
}
}
}
}),
dataType: "object",
pageable: false,
toolbar: ["create"],
columns: [{
field: "productID",
title: "id"
},
{
field: "productName",
title: "Name"
},
{
field: "productCategory",
title: "Category",
template: "1",
editor: productCategoryDropDownEditor,
},
{
field: "productDiscount",
title: "Discount"
},
{
command: "destroy",
title: "x",
width: 29
},
],
editable: true,
sortable: true,
resizable: true
});
$("#addPrice").click(function() {
addPriceDialog.data("kendoDialog").open();
});
addPriceDialog.kendoDialog({
width: "450px",
title: "Add price",
closable: true,
modal: true,
actions: [{
text: 'Cancel',
action: function() {
return false;
},
},
{
text: 'Ок',
primary: true,
action: function() {
let name = $("#priceName ").val();
let type = $("#priceType").val();
let val = $("#priceValue").val();
let price = $("#price").val();
let grid = $("#gridProduct").data("kendoGrid");
let columns = grid.columns;
let newCol = {
title: "Price -" + name,
field: "price" + type + [columns.length],
format: "",
};
$("#gridTicket").data("kendoGrid").columns[(columns.length)] = newCol;
return true;
},
}
]
});
You can use setOptions to redefine the columns of the grid.
See the snippet for a demo.

I am using a kendoui grid for which autoBind config is set to false. I want to bind data on click of a button. i do not want to make use of datasource.read() as it make additional server side call. I already have data available which I want to bind to the grid.
See the fiddle for more info

Use data() instead:
$("#buttonGrid").click(function(){
//How to bind the data available as products
$("#grid").data("kendoGrid").dataSource.data([
{ ProductName: "Test1", UnitPrice: 1, UnitsInStock: 1, Discontinued: false }
]);
});

The Filter basically works fine but,
The select does not seem to fire the first selection
this happens every time the filter is reset as well.

Change your kendo library to 2014 or previous version will make it works fine,

We have not implement able to configure the Combobox. we can simply built the select box with following options. We just update the Status from Combobox.
Thanks

You can refer to this official example off the KendoUI demos to set the custom editor up correctly.
