Kendo UI call custom service for delete - kendo-ui

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.

How to get value id from dataSource by row Kendo UI Grid

Help me code How to get value id from dataSource by row and change to current value default (1)
in line: var date = dataSource.get(1);
console.log(date.ProductName)
My full source:
<div id="grid"></div>
<script>
$(document).ready(function () {
var crudServiceBaseUrl = "https://demos.telerik.com/kendo-ui/service",
dataSource = new kendo.data.DataSource({

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);
}
});

How I write a dynamic URL in kendo UI DataSource like "update/{id}"

I have a web API. In that I wrote a update method. But it need to id of the table row to update to the row.
I use a grid to show data and use a toolbar to edit the row.
My question is how I pass that id to the update.
Can someone guide me ??
update: function(options) {
$.ajax( {
url: function(data) { return "updateUsuarios/"+data.Id,
dataType: "json",
.....
Well i suggest you, explain more your question, but i think this examples could help , if you have a toolbar as a template like this:
<script type="text/x-kendo-template" id="template">
<div class="toolbar">
<button type="button" id="update">Update</button>
</div>
</script>
You "grid" need the attr "toolbar"
$("#grid").kendoGrid({
dataSource: dataSource,
pageable: true,
height: 550,
filterable:true,
toolbar: kendo.template($("#template").html()),
columns: [
{ field:"username", title: "Username" , width: "120px" },
{ field: "nombre", title:"Nombre", width: "120px" },
{ field: "apellido", title:"Apellido", width: "120px" },
{ field: "ci", title:"Documento de Identidad", width: "120px" },
{ field: "email", title:"Direccion de Correo", width: "120px" },
{ field: "activo",title:"Estatus", width: "120px" },
{ field: "fecha_caducidad",title:"Fin Demo", width: "120px",template: "#= kendo.toString(kendo.parseDate(fecha_caducidad, 'yyyy-MM-dd'), 'MM/dd/yyyy') #" },
{ field: "licencia_status",title:" ", width: "40px",template:'<img src="assets/images/#:data.licencia_status#.png"/>' },
{ command: ["edit"], title: " ", width: "120px" }],
editable: "popup",
dataBound: function () {
var rows = this.items();
$(rows).each(function () {
var index = $(this).index() + 1;
var rowLabel = $(this).find(".row-number");
$(rowLabel).html(index);
});
},
selectable: true
});
So,you can configure a kendo button and add functionality in the event click:
$("#update").kendoButton({
click: function(){
//Here you will have the selected row
var self=$('#grid').data('kendoGrid')
var index = self.items().index(self.select());
var rowActual= self.dataSource.data()[index];
rowActual=self.dataItem(self.select());
if(rowActual==undefined || rowActual ==null) {
alert("No row selected");
}else{
$.ajax({
type: "POST",
url: "update",
data: {
id:rowActual.id
},
dataType: 'json',
success: function (data) {
},
error: function(){
}
});
}
}
});
and send in the ajax the row id, but if you are update the row with the inline edition you could try with a datasource like this
dataSource = new kendo.data.DataSource({
transport: {
read: function(options) {
$.ajax( {
url: "readUsuarios",
dataType: "json",
success: function(result) {
options.success(result);
}
});
},
update: function(options) {
$.ajax( {
url: "updateUsuarios",
dataType: "json",
data: {
models: kendo.stringify(options.data.models)
},
success: function(data) {
// response server;
},
error: function(result) {
// notify the data source that the request failed
options.error(result);
}
});
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "id",
fields: {
username: { editable: false, nullable: true },
nombre: { validation: { required: true } },
apellido: { type: "string", validation: { required: true} },
ci: { type: "string", validation: { required: true} },
email: { type: "string", validation: { required: true } },
activo: { type: "boolean",editable: false },
fecha_caducidad: { type: "date" },
licencia_status:{editable: false}
}
}
}
});
I hope this help!

In kendo grid Update button is not firing

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.

Kendo UI DataSource not triggering transport.destroy

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: "&nbsp", 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"
