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:

Now, when click edit, all rows only get fields of id 1. I want corresponding id instead of the default id 1.
edit
Fired when the user edits or creates a data item.
The event handler function context (available via the this keyword)
will be set to the widget instance.
EVENT DATA
e.container jQuery The jQuery object of the edit container
element, which wraps the editing UI. Depending on the Grid edit mode,
the container is different:
"incell" edit mode - the container element is a table cell
"inline" edit mode - the container is a table row
"popup" edit mode - the container is a Kendo UI Window element, which provides an easy way to obtain a reference to the Window widget object, e.g. to attach additional events.
e.model kendo.data.Model The data item which is
going to be edited. Use its isNew method to check if the data item is
new (created) or not (edited).
e.sender kendo.ui.Grid The widget instance which fired the event.
$("#grid").kendoGrid({
columns: [
{ field: "id" },
{ field: "name" },
{ field: "age" },
{ command: "edit" }
],
dataSource: {
data: [
{ id: 1, name: "Jane Doe", age: 30 },
{ id: 2, name: "John Doe", age: 33 }
],
schema: {
model: {
id: "id",
fields: {
"id": { type: "number" }
}
}
}
},
editable: "popup",
toolbar:["create"],
edit: function(e) {
console.log(e.model.id);
console.log(e.model.name);
}
});

I created a KendoUI grid where the first column uses a custom editor. After editing, it doesn't call request of update, however if it is not using editor it will call request of update. Why?
var columns = [
{ field: 'AccountId', title: '客户名称', locked: false, template: '#= me.detail.brandName(data, \'ID\') #', editor: accountGridEditor, width: 200 },
{ field: 'BankNo', title: '付款银行', template: '#= me.detail.format(data, \'Bank\') #', attributes: { style: 'text-align: left;' }, width: 150 },
{ field: 'UnLinkedAmount', title: '未分配', template: '#= me.detail.format(data, \'UnLinkedAmount\') #', attributes: { style: 'text-align: left;' }, width: 100 },
{ command: ["edit", "destroy"], title: " ", width: "250px" }
];
var dataSource = c.dataSourceOption({
transport: {
read: { url: url.api('Finance/FundJournal') },
update: { url: url.api('Finance/FundJournal', { action: 'post' }) },
destroy: { url: url.api('Finance/FundJournal', { action: 'delete' }), type: 'delete' },
parameterMap: function (data, type) {
console.log(type);
console.log(data);
if (type === 'read') return getReadParameters();
if (type === "update") return data;
if (type === 'create') return data;
if (type === 'destroy') return { id: data.Id };
return data;
}
},
schema: {
model: {
id: "Id",
fields: {
AccountId: { editable: true, nullable: false, validation: { required: true } },
BankNo: { editable: false},
UnLinkedAmount: { editable: false }
}
}
},
filter: [{ field: 'SubType', operator: 'neq', value: 'Id' }]
});
var grid = $("#result").kendoGrid({
dataSource: dataSource,
height: 550,
columns: columns,
editable: "inline",
save:function(e){$.ajax();}
}).data('kendoGrid');
If record property is set from dropdownlist something like this:
change: function() {
options.model.Name = this.value();
options.model.dirty = true;
}
it is necessary explicitly to set that model as dirty, to say to datasource that this record was modified and need to be updated. Otherwise, you can use set().
change: function() {
options.model.set('Name',this.value());
}
That way record is automatically marked as dirty in datasource.
How can I call custom service for deleting a row in Kendo UI grid.This custon service should have a confirmation dialog option that can be customized.
Any thoughts on this is highly appreciative
You should customize the kendo.data.DataSource 'destroy' attribute to specify the URL and update the kendoGrid 'delete' command code for the custom confirmation.
Example code
$(document).ready(function () {
var windowTemplate = kendo.template($("#windowTemplate").html());
var crudServiceBaseUrl = "http://demos.kendoui.com/service",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/Products",
dataType: "jsonp"
},
update: {
url: crudServiceBaseUrl + "/Products/Update",
dataType: "jsonp"
},
destroy: {
url: crudServiceBaseUrl + "/Products/Destroy",
dataType: "jsonp"
},
create: {
url: crudServiceBaseUrl + "/Products/Create",
dataType: "jsonp"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: { validation: { required: true } },
UnitPrice: { type: "number", validation: { required: true, min: 1} },
Discontinued: { type: "boolean" },
UnitsInStock: { type: "number", validation: { min: 0, required: true } }
}
}
}
});
var window = $("#window").kendoWindow({
title: "Are you sure you want to delete this record?",
visible: false, //the window will not appear before its .open method is called
width: "400px",
height: "200px",
}).data("kendoWindow");
var grid = $("#grid").kendoGrid({
dataSource: dataSource,
pageable: true,
height: 430,
toolbar: ["create"],
columns: [
"ProductName",
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}"},
{ field: "UnitsInStock", title:"Units In Stock"},
{ field: "Discontinued"},
{ command: [
{name: "edit"},
{name: "Delete",
click: function(e){ //add a click event listener on the delete button
var tr = $(e.target).closest("tr"); //get the row for deletion
var data = this.dataItem(tr); //get the row data so it can be referred later
window.content(windowTemplate(data)); //send the row data object to the template and render it
window.open().center();
$("#yesButton").click(function(){
grid.dataSource.remove(data) //prepare a "destroy" request
grid.dataSource.sync() //actually send the request (might be ommited if the autoSync option is enabled in the dataSource)
window.close();
})
$("#noButton").click(function(){
window.close();
})
}
}
]}],
editable: {
mode: "inline"
}
}).data("kendoGrid");
});
Taken from:
http://docs.telerik.com/kendo-ui/web/grid/how-to/Editing/custom-delete-confirmation-dialog
You can set the delete option in your datasource to a function and do anything you want from that point. Without a sample of your service, I can't help you getting started but I can link you to the documentation.
I have Kendo UI inline Grid. It read and populate the grid properly. but when i press edit and changes in any column and press update then update event is not firing. and it also not calling controller method.
my view
$(document).ready(function () {
dataSource = new kendo.data.DataSource({
transport:
{
read:
{
url: "/Student/StudentGrid",
contentType: "application/json; charset=utf-8",
dataType: "json",
type: "GET"
},
update:
{
url: "#Url.Action("EditStudentDetails")",
contentType: "application/json;charset=utf-8",
dataType: "json",
type: "POST"
},
parameterMap: function (options, operation) {
if (operation != "read" && options) {
if (operation != "destroy") {
return JSON.stringify({
studentViewModel: options
});
}
else if (operation == "destroy") {
return JSON.stringify({
id: options.Id
});
}
}
}
},
parse: function (test) {
if (test.success) {
if (test.type != "read") {
alert(test.message);
$("#grid").data("kendoGrid").dataSource.read();
}
return test.data;
}
else {
alert(test.message);
return [];
}
}
})

What i did wrong in this and when i click on edit button it is changing to editable mode but when i click on update it is not working
Is any of your cell text has HTML tags like "<" or ">", remove them and click on update and check the update event fire.
I am using Kendo UI with ASP.NET Web API. There is a ProjectsController that has all the necessary methods.
My issue is that when I click on Delete button, Kendo UI grid will raise remove() event, but DataSource never invokes transport.destroy. Rather, it seems that tansport.create is being invoked. In transport.parameterMap I can see that the operation is create instead of destroy.
Here is a sample JavaScript code:
$(document).ready(function () {
var apiUrl = '/api/projects/';
var dataType = 'json';
var dataSource = new kendo.data.DataSource({
batch: true,
autoSync: false,
transport: {
read: {
url: apiUrl,
dataType: dataType,
type: "GET"
},
update: {
url: apiUrl,
dataType: dataType,
type: "PUT"
},
destroy: {
url: apiUrl,
type: "DELETE"
},
create: {
url: apiUrl,
contentType: "application/json;charset=utf-8",
dataType: dataType,
type: "POST"
},
parameterMap: function (data, operation) {
console.log("Operation: " + operation);
if (operation === "create" && data.models) {
for (var i in data.models) {
var model = data.models[i];
if (model.ProjectId === 0) {
return kendo.stringify(model);
}
}
} else if (operation === "destroy") {
console.log("Data.Models: " + data.models);
console.log("Data.id: " + data.ProjectId);
return { id: data.ProjectId };
}
return data;
}
},
schema: {
id: "ProjectId",
model: {
fields: {
ProjectId: { type: "number", editable: false, nullable: false, defaultValue: 0 },
ProjectName: { type: "string", validation: { required: true } },
Status: { type: "string", validation: { required: true } },
IsActive: { type: "boolean" }
}
}
},
pageSize: 10,
serverPaging: false,
serverFiltering: false,
serverSorting: false
});
$("#projectsGrid").kendoGrid({
dataSource: dataSource,
groupable: false,
sortable: true,
pageable: {
refresh: true,
pageSizes: true
},
pageSize: 10,
toolbar: ["create"],
editable: "popup",
columns: [
{ field: "ProjectId", width: 30, title: "ID" },
{ field: "ProjectName", width: 180, title: "Project" },
{ field: "Status", width: 90, title: "Status" },
{ field: "IsActive", width: 40, title: "Is Active", type: "boolean", template: '<input type="checkbox" #if (IsActive) {# checked="checked" #}# disabled="disabled" />' },
{ command: ["edit", "destroy"], title: " ", width: "80px" }
],
remove: function (e) {
console.log("Delete button clicked.");
console.log("Project ID: " + e.model.ProjectId);
//dataSource.remove(e.model);
//dataSource.sync();
}
});
});
Web API works fine when requests are issued via Fiddler, but Kendo UI Grid shows:
POST http://localhost:port/api/Projects
when it should be DELETE.
Thanks everyone in advance!
On your datasource, you have the batch flag set to true, this means the datasource will make the call only after you tell it to, e.g calling sync().
http://docs.kendoui.com/api/framework/datasource#configuration-batch
As well as
Make sure you have defined Id in the model, as OnaBai explained here Why does the KendoUI Grid Transport Create event gets raised multiple times, and even when the action is Update? , your id is outside the model, should be in :
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
}
}
if someone has defined the id in model as answered in above ,but dataSource not triggering transport.destroy yet ,below configuration could be helpful:
editable: {
..
mode: "inline", //or "popup
...
}
//or
editable: "inline" //or "popup"
