I am using Kendo Grid and filterable mode row. One of the columns is using a kendoDatePicker.
I filter on server and my problem is, when I pick a value on the datePicker, filtering works fine, but when it shows the data, the value doesn't stay in filter input, it disappears.
I am using to set the DatePicker:
$(document).ready(function () {
var grid = $("#grid").kendoGrid({
dataSource: {
transport: {
read: {
url: "/kukatko/search",
dataType: "json",
cache: false
},
parameterMap: function (data, type) {
if (type == "read") {
var paramMap = kendo.data.transports.odata.parameterMap(data.filter);
return paramMap;
}
}
},
serverFiltering: true,
pageSize: 10
},
filterable: {
mode: "row"
},
sortable: true,
pageable: true,
reorderable: true,
columns: [{...(some other columns)...
}, {
field: "datumZalozenia",
title: "Dátum založenia",
width: "150px",
parseFormats: ["d.M.yyyy"],
format: "d.M.yyyy",
template: "#=kendo.toString(new Date(datumZalozenia), 'd')#",
filterable: {
cell: {
showOperators: false,
operator: "contains",
format: "{0:d.M.yyyy}",
template: function (args) {
args.element.kendoDatePicker({
format: "d.M.yyyy"
});
}
}
}
Here is an image of how it looks (before, select value and after):
I selected 15.7.2015 so filtering on server runs without any problems.

I'm quite new using kendo grids.
So far I've managed to do a few stuff and got a workaround for all my problems.
I have a grid with 2 columns.
One column is a product code that the user should enter, and the other is product quantity that should be filled automatically after the user enter the product code. This should be done on change event.
The product quantity is obtained by a service.
So far I have the following code:
var dataSource = new kendo.data.DataSource({
batch: false,
autoSync: false,
data: [],
pageSize: 20,
schema: {
model: {
id: "ProductID",
fields: {
ProductCode: { type: "string", validation: { required: true } },
ProductQuantity: { type: "number", validation: { required: false, editable: false } }
}
}
},
edit: function (e) {
if (e.model.isNew() == false) {
$('[name="ProductQuantity"]').attr("readonly", true);
}
},
change: function (e) {
if (e.action == "itemchange") {
debugger;
apModel.getProductQuantities(e.items[0].ProductCode).ifFetched().then(function (data) {
var data = JSON.parse(data.Response);
})
//how to access next cell???
$("#ap-grid").data("kendoGrid").saveRow();
}
}
});
$("#ap-grid").kendoGrid({
dataSource: dataSource,
pageable: false,
height: 550,
toolbar: ["create"],
columns: [
{ field: "ProductCode", title: "Product Code" },
{ field: "ProductQuantity", title: "Quantity" },
{ command: ["edit", "destroy"], title: " ", width: "250px" }],
editable: "inline",
});
I can't find a way how to access the next cell to add the data to it.
Can you give me a hint?
thanks in advance,
André
When you set e.items[0].ProductQuantity in OnChange event handler grid cell should automatically update value if datasource bind correctly.
According to kendo docs:
e.items - The array of data items that were affected (or read).
That means it reference at original row of datasource.
I have a simple Kendo UI Grid. The gird is in batch mode and works fine. I am using Web API to bind the actual CRUD methods.
I have to show hide the Toolbar Buttons conditionally. How and Where (which event) can I create this kind of functionality
For example:
If(user.Role.Permission == "Edit"){
//Show Edit Button else hide
}
Here is the Actual Kendo UI Grid Code
var baseUrl = "/api/TicketType";
var datatype = "json";
var contentType = "application/json";
var datasource = new kendo.data.DataSource({
serverPaging: true,
pageSize: 10,
autoSync: false,
batch: true,
transport: {
read: {
url: baseUrl,
dataType: datatype,
contentType: contentType
},
create: {
url: baseUrl,
dataType: datatype,
contentType: contentType,
type: "POST"
},
update: {
url: baseUrl,
dataType: datatype,
contentType: contentType,
type: "PUT"
},
parameterMap: function (data, operation) {
if (operation !== "read" && data.models) {
return kendo.stringify(data.models);
}
else {
return {
take: data.take,
skip: data.skip,
pageSize: data.pageSize,
page: data.page
}
}
}
},
schema: {
data: "data.$values",
total: "recordCount",
model: {
id: "TypeID",
fields: {
TypeID: { editable: false, type: "number" },
TypeCode: { editable: true, nullable: false, validation: { required: true } },
Description: { editable: true, nullable: false, validation: { required: true } }
}
}
}
});
$("#Grid").kendoGrid({
dataSource: datasource,
toolbar: [
{name: "create", text: "Add New Record"},
{ name: "save", text: "Save Changes" },
{ name: "cancel", text: "Cancel Changes" },
],
columns:
[
{ field: "TypeID", width: 50, title: "ID"},
{ field: "TypeCode", width: 150, title: "Code"},
{ field: "TypeDescription", width: 200, title: "Description"}
]
})
datasource.read(); // This will bind to the grid.
});
Please try with the below code snippet.
$(document).ready(function () {
hidetoolbar();
});
function onDataBound(arg) {
hidetoolbar();
}
function onDataBinding(arg) {
hidetoolbar();
}
function hidetoolbar(){
If(user.Role.Permission != "Edit"){
$("#Grid .k-add").parent().hide();
$("#Grid .k-update").parent().hide();
$("#Grid .k-cancel").parent().hide();
//OR
$("#Grid .k-add").parent().remove();
$("#Grid .k-update").parent().remove();
$("#Grid .k-cancel").parent().remove();
}
}
$("#Grid").kendoGrid({
dataSource: datasource,
dataBound: onDataBound, // Added
dataBinding: onDataBinding, //Added
toolbar: [
{name: "create", text: "Add New Record"},
{ name: "save", text: "Save Changes" },
{ name: "cancel", text: "Cancel Changes" },
],
columns:
[
{ field: "TypeID", width: 50, title: "ID"},
{ field: "TypeCode", width: 150, title: "Code"},
{ field: "TypeDescription", width: 200, title: "Description"}
]
});
If you want to show or hide the toolbar button, you will need to implement the logic in the Databound event of the Grid.
Please see the below example:
JSBin Databound example

I would like to disable DiscountPercentageMRC/NRC/Usage columns for certain CatalogProductId's. Please find below javascript for the grid. Any help would be greatly appreciated.
<h2>Kendo Grid bound to ASP.NET MVC action methods</h2>
#* The DIV where the Kendo grid will be initialized *#

$(document).ready(function () {

{ field: "CompanyName" },
{ field: "DiscountPercentageMRC" },

type: "POST",
}
}
},

});
});
</script>
You would use the Edit event to enable/disable cells. I created a working example here: http://jsfiddle.net/Eh8GL/151/
function OnEdit(e) {
// Make sure it's not a new entry
if (!e.model.isNew()) {
var catalogproductid = e.container.find("input[name=CatalogProductId]").data("kendoNumericTextBox").value();
// Disable DiscountPercentageMRC if catalog productid = 100
if (catalogproductid == 100) {
var disableField = e.container.find("input[name=DiscountPercentageMRC]").data("kendoNumericTextBox");
disableField.enable(false);
}
}
}
I cannot get Kendo Grid to populate from server side data.
I have a grid builder function as as follows:
var build = function (carrier, date) {
var urlBase = 'my base url';
var datasource = new kendo.data.DataSource({
pageSize: 20,
serverPaging: true,
serverFiltering: true,
serverSorting: true,
schema: {
model: {
id: 'Id',
fields: {
StatementDate: { type: "string", editable: false },
CobDate: { type: "string", editable: false },
//lots more fields
Status: { type: "string", editable: false },
Matched: { type: "boolean", editable: true }
}
}
},
transport: {
read: function (options) {
var address = urlBase + '/' + carrier + '/' + date;
$.ajax({
url: address,
type: "POST",
data: JSON.stringify(options.data),
contentType: "application/json",
success: function (result) {
options.success(result);
},
error: function (result) {
options.error(result);
}
});
},
//update function omitted
parameterMap: function (data, operation) {
if (operation == "read") {
return JSON.stringify(data)
}
},
change: function (e) {
var data = this.data();
console.log(data.length); // displays "77"
}
}
});
return datasource;
};
return {
build: build
}
Grid Definition
elem.kendoGrid({
columns: [
{ field: "StatementDate", title: "State Date", width: 125 },
{ field: "CobDate", title: "COB Date", width: 100 },
//lots more fields
{ command: ["edit"], title: " ", width: "85px"}],

change: this.onSelectedRecordChanged,
toolbar: kendo.template($('#' + templateName).html()),
scrollable: {
virtual: true
},
height: 800
});
I trigger the update via a button click. When I look at the response I see the data. Looks good but the grid will not show the data. It has previously worked fine when data was completely client side.
If I break point on the AJAX call back. I see the correct results.
The grid is bound with data bind. The datasource is a property on a viewmodel.
<div id="grid" data-bind="source: dataSource"></div>
At the start of the app. I create view model
var viewModel= kendo.observable(new GridViewModel(...
and bind
kendo.bind($('#grid'), viewModel);
If I look at the datasource attached to the grid, I see data for the page as expected
This has previously worked fine when data was client side.
I have tried using read() on datasource, and refresh() method on grid. Neither seems to work.
Example response content from server
{"Data":[{"Id": //lots more fields, 20 records],"Total":90375,"AggregateResults":null,"Errors":null}
Any help very much appreciated.
I found the cause in datasource schema missing
{ data: 'Data', total: 'Total' }
I am trying to implement server side sorting with kendo grid in my MVC application. but sorting option is not showing. i have double checked that i have enabled all the necessary option (made the serversorting to true to the the kendo grid data source and made the scrollable to true to the grid element) to do this but still i am able to find the sortable option. below is my kendo grid code
Kendo Grid Script
var grid = $("#grid");
grid.children().remove();
grid.kendoGrid({
columns: [{attributes:"",field:"",template:"${ResultFields[0].Value},title:"Column 1",width:"110px"},{attributes:"",field:"",template:"${ResultFields[1].Value},title:"Column 1",width:"110px"}],
resizable: true,
reorderable: true,
scrollable: true,
filterable: true,
columnMenu: true,
selectable: "row",
selectable: "multiple",
dataBound: function () { alert("Data Bound"); },
dataSource: {
transport: {
read: {
url: '#Url.Action("Index", "KendoServerSideSorting")',
type: "GET",
dataType: "json",
traditional: true,
data: {
itemTypeId: 1,
where: values,
orderBy: ["", "", ""],
},
},
},
schema: {
data: "Items",
total: "TotalItems",
},
serverPaging: true,
pageSize: 10,
error: function (e) {
alert(e.errors);
}
},
pageable: {
pageSize: 10,
input: true,
pageSizes: [10, 20, 30, 50, 100, 250],
},
change: function () { alert("Change event"); },
})
Controller Action will look like this
public JsonResult Search(int itemTypeId, int skip, int take, string[] where, string[] orderBy)
{
var v = Kernel.Get<IItemSearch>().Search(itemTypeId, skip, take, where, orderBy);
return Json(v, JsonRequestBehavior.AllowGet);
}
*Can anyone help me to resolve this issue. *
You can use the helper functionality from KendoGridBinderEx to parse all the commands (like filter and sort) and do the filtering and sorting at the server-side automatically using DynamicLinq.
