I'm trying to implement some functionality in "onchange" of text box in telerik kendo grid. But it is not firing in change; instead it's firing on onBlur.
The code is here. demo
To track the changes in the editors inside the column templates you should use different approach. Please check the example below:
$("#grid").kendoGrid({
columns: [ {
field: "name",
template: kendo.template($("#name-template").html())
}],
dataSource: {
data: [ {id: 1, name: "Jane Doe" }, {id: 2, name: "John Doe" } ],
//schema is required for enabling valid CRUD operations
schema: {
model: {
id: "id",
fields: {
id: {type: "number"},
name: {type: "string"}
}
}
}
}
});
var grid = $("#grid").data("kendoGrid");
grid.table.on("change", "input", function(e) {
alert("change");
//optionally update the underlying model:
var editor = $(this);
var dataItem = grid.dataItem(editor.closest("tr"));
dataItem.set("name", editor.val());
});
Another option is to use the MVVM approach shown in the following demo:

I've used "onkeyup" event. It works :)
You should try "onkeypress" event. It will work as per your requirement.

I have an existing grid creating in Kendo UI for Jquery. I want to put a static drop down/select box in the first field/cell of the grid on each row. When I do it shows up as "undefined".
Most of the examples I see on her and the Telerik site use an editor. In my case the drop down is static. Once they click on an item they will be redirect to another page to do something. At the moment I just want to get the drop down to show up with hard coded options.
jQuery(function($){
"use strict";
var grid = $("#grid").kendoGrid(){
....
columns: [{
field: "my_links",
title: "My Links",
template: "#=getMyLinks(DATA.user_id)#"
},{
....
}_.data("kendoGrid");
function setGridData(){
....
});
grid.setDataSource(dataSource);
}
setGridData();
});
function getMyLinks(user_id){
$('<input id="my_links" name="my_links/>')
.kendoDropDownList{[
dataSource: [
{ id: 1, name: "View" },
{ id: 2, name: "Create },
{ id: 3, name: "Delete"}
],
dataTextField: "name",
dataValueField: "id"
});
}
I would expect a drop down in the
You should provide DOM element for drop down widget in columns.template field and then initialize all widgets in dataBound event.
$("#grid").kendoGrid({
columns: [{
field: "my_links",
title: "My Links",
template: "<input id="my_links" name="my_links/>"
}],
dataBound: function (){
getMyLinks(DATA.user_id);
}
}).data("kendoGrid");
I have a Kendo Grid where the COR ABA No. may or may not be editable, depending on a value in the first column. So, if NOC Code=='C01', then COR ABA No. is editable, otherwise it is not.
I have achieved this by adding the Edit event on the columns and in that edit handler disabling the HTML input Kendo creates, when no editing is allowed. (In the grid definition, I have Editable(true) to start). I want instead to do this by doing the logic check in the DataBound event for the grid. That is, after all data is bound, iterate over the data, determine when the column should NOT be editable, and prevent this somehow. My idea is to simply remove the click handler that I ASSUME Kendo adds for a cell when using Editable(true) as stated above. Is this the way? Or how? Thanks!
I suggest another way, instead call closeCell() on edit event, if you do not want to allow the user to edit the cell. In doing so, the cell will not display an input when the user clicks it to edit it.
<div id="grid"></div>
<script>
$("#grid").kendoGrid({
columns: [
{ field: "id" },
{ field: "name" },
{ field: "age" }
],
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: "incell",
toolbar:["create"],
edit: function(e) {
if (!e.model.isNew() && e.container.index() == 0) {
var grid = $("#grid").data("kendoGrid");
grid.closeCell();
}
}
});
</script>
I want to set the datasource for a kendoui treelist at the run time. Please check following example. If I set the datasource at the design time, I am able to see the data in the control. But if I try to set the datasource at run time, I do not see the data in the control.
<div id="treeList"></div>
<script>
var data = [ { name: "Jane Doe" }, { name: "John Doe" }];
var dataSource = new kendo.data.TreeListDataSource({
data: [ { name: "Jane Doe" }, { name: "John Doe" }]
});
$("#treeList").kendoTreeList({
columns: [
{ field: "name" },
{ command: [{ name: "edit" }] }
],
editable: true
//,dataSource: dataSource
});
var grid = $("#treelist").data("kendoTreeList");
grid.setDataSource( dataSource);
grid.dataSource = dataSource;
grid.dataSource.read();
grid.dataSource.data(data);
</script>
The problem seems to be with the selector itself. You logic was ok but for some reason, the object returned by data("kendoTreeList") was null. I updated your code to chain the data after the kendoTreeList initialization.
var dataSource = new kendo.data.TreeListDataSource({
data: [ { name: "Jane Doe" }, { name: "John Doe" }]
});
var grid = $("#treeList").kendoTreeList({
columns: [
{ field: "name" },
{ command: [{ name: "edit" }] }
],
editable: true
}).data("kendoTreeList");
grid.setDataSource(dataSource);
It's a bit odd to say but I thought your code and my code would be equivalent. Obviously, it ain't but I can't figure out why.
Your main problem is that you have the id to the DOM element set to "treeList".
var grid = $("#treelist").data("kendoTreeList");
As you can see here, you use all lowercase when setting the grid variable. That was your only problem. It should look like this:
var grid = $("#treeList").data("kendoTreeList");
I am using Telerik's Kendo UI and their autocomplete widget in conjunction with their MVVM framework, and am having a bit of a hard time with getting a box to set the retrieved (and selected) object to the bound one on the view model. For example...
var viewModel = kendo.observable({
Context: {}
});
$("#context").kendoAutoComplete({
dataTextField: "Name",
dataValueField: "Id",
delay: 800,
dataSource: {
dataType: "json",
serverFiltering: true,
transport: {
read: {
url: "/search/data",
data: function (data) {
return {
term: data.filter.filters[0].value
}
}
}
}
}
}).data("kendoAutoComplete");
Then I use the following HTML;
<input data-val="true"
id="context"
name="context"
placeholder="Context"
type="text"
data-bind="value: Context" />
This hits a controller action that returns the following;
[
{
Id: "items/1",
Name: "Item 1",
Label: "Item 1 Label"
},
{
Id: "items/2",
Name: "Item 2",
Label: "Item 2 Label"
},
{
Id: "items/3",
Name: "Item 3",
Label: "Item 3 Label"
}
]
However when I select the object after using the autocomplete to search for it, the Context property on my viewmodel remains null.
I can circumvent this by adding a specific select function.
select: function(e) {
var dataItem = e.sender.dataItem(e.item.index()).toJSON();
// update the model
viewModel.set('Context', dataItem);
}
but I would really rather just it work like it is supposed to; Any suggestions?
The problem is that you define viewModel as an Observable object but you are not binding it to the input.
Try adding the binding as follow:
kendo.bind($("#context"), viewModel);

I have a kendo ui grid. Let's say that the JS variable pointing to the grid is called grid. How can I go to page 3 programmatically? Thanks.
You might to use:
grid.dataSource.query({ page: 3, pageSize: 20 });
Documentation in here.
or:
grid.dataSource.page(3);
Documentation in here
Answer is just set it pate: 1 when datasource created
var dataSource = new kendo.data.DataSource({
data: [
{ name: "Tea", category: "Beverages" },
{ name: "Coffee", category: "Beverages" },
{ name: "Ham", category: "Food" }
],
page: 1,
// a page of data contains two data items
pageSize: 2
});
