popup kendo window when clicked on grid data - kendo-ui

I have created a kendo grid for 10 number of products in my project. I want the kendo window containing the details of the product to popup when I click on the productname displayed in the kendo grid.
I have looked into the demos of the kendo grid but I don't want the details of the product selected to be edited and also I don't want to use a separate column for details button as shown in the examples and demo.
I also looked into the music store demo of kendo ui but I couldn't understand its code as its in jQuery and I am using asp.net mvc with razor syntax for my project
Note:
I want window to appear only when I click on the name of the product and display its details.

You can use:
$('#grid').on("click", "tr.k-state-selected", function (e) {
// open window here
// you have i.e. Id here $('#grid').dataItem($('#grid').select()).Id
});
For this you must set option selectable: "row" in grid configuration.
Otherwise you can use just:
$('#grid').on("click", "tr", function (e) { ... }

You can make use of the detailTemplate for achieving it.
<script>
var wnd,
detailsTemplate;
$(document).ready(function () {
var grid = $("#grid").kendoGrid({
dataSource: {
pageSize: 20,
data: createRandomData(50)
},
pageable: true,
height: 550,
columns: [
{ field: "FirstName", title: "First Name", width: "140px" },
{ field: "LastName", title: "Last Name", width: "140px" },
{ field: "Title" },
{ command: { text: "View Details", click: showDetails }, title: " ", width: "180px" }]
}).data("kendoGrid");
wnd = $("#details")
.kendoWindow({
title: "Customer Details",
modal: true,
visible: false,
resizable: false,
width: 300
}).data("kendoWindow");
detailsTemplate = kendo.template($("#template").html());
});
function showDetails(e) {
e.preventDefault();
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
wnd.content(detailsTemplate(dataItem));
wnd.center().open();
}
</script>
<script type="text/x-kendo-template" id="template">
<div id="details-container">
<h2>#= FirstName # #= LastName #</h2>
<em>#= Title #</em>
<dl>
<dt>City: #= City #</dt>
<dt>Birth Date: #= kendo.toString(BirthDate, "MM/dd/yyyy") #</dt>
</dl>
</div>
</script>
Go to this fiddle for a working demo
[UPDATE]
Here's the code snippet for showing the window while clicking on the Product Name
<script>
var wnd,
detailsTemplate;
$(document).ready(function () {
var grid = $("#grid").kendoGrid({
dataSource: {
pageSize: 20,
data: createRandomData(50)
},
pageable: true,
height: 550,
columns: [
{ field: "FirstName", title: "First Name", width: "140px",attributes: { "class": "FirstName"} },
{ field: "LastName", title: "Last Name", width: "140px" },
{ field: "Title" }]
}).data("kendoGrid");
wnd = $("#details")
.kendoWindow({
title: "Customer Details",
modal: true,
visible: false,
resizable: false,
width: 300
}).data("kendoWindow");
detailsTemplate = kendo.template($("#template").html());
$('#grid').on("click", ".FirstName", function (e) {
e.preventDefault();
var dataItem = $("#grid").getKendoGrid().dataItem($(e.currentTarget).closest("tr"));
wnd.content(detailsTemplate(dataItem));
wnd.center().open();
});
});
</script>
<script type="text/x-kendo-template" id="template">
<div id="details-container">
<h2>#= FirstName # #= LastName #</h2>
<em>#= Title #</em>
<dl>
<dt>City: #= City #</dt>
<dt>Birth Date: #= kendo.toString(BirthDate, "MM/dd/yyyy") #</dt>
</dl>
</div>
</script>

kendo customised TreeList manual adding childnode unexpected result

List item
I have a page which loads a kendo TreeList by pressing a button. The data is for the moment statically defined in a variable where it stays as a basis for the Kendo TreeList datasource.
I have a datasource definition which I mostly copied from Telerik Website.
I have a treelist with a couple of requirements in terms of CRUD.
level1 - nothing
level2 - add new childnodes only
level3 - edit and delete
Edit should be doubleclick on a level3 item
CRUD command buttons need to be icon-only (no text in the buttons)
I could not achieve this with the buildin CRUD controls unfortunately so I used a Template column where the buttons are placed based on their "Type" field.
Now this has worked but after some changes which I can't undo somehow the add function does not work anymore. It works but new childnode is only visible after a edit ordelete of another node. (as if the change event is not triggered during add). The Add button in the treeList calls a function addProduct where at the end I try to pushCreate directly to the datasource. However the Transport.create is never invoked. It only gets invoked after another Crud action triggers it
Can anybody see what's wrong and couldn't this all be achieve with much easier approach?
Here's the page:

</script>
</body>
</html>
I found the answer !!!
The datasource pagesize is set to 10 and the TreeList was set to paging: false. In all my tests I started with sample data of 10 nodes. All the time I was adding an 11th and 12th record which wasn't showing up until I deleted another node...
Do these things only happen to me?

Telerik Kendo UI with MVVM

I have one Kendo UI Grid in my view page (MVVM Concept). Bind the data from view model. When I reduce the page size.
Kendo UI grid change to Kendo UI Listview. See this image:
How can I do this?
Define one single DataSource for both Grid and ListView.
var ds = {
data : ...,
pageSize: 10,
schema : {
model: {
fields: {
Id : { type: 'number' },
FirstName: { type: 'string' },
LastName : { type: 'string' },
City : { type: 'string' }
}
}
}
};
Then define both a DIV for the Grid and for the ListView:
<div id="grid"></div>
<div id="list"></div>
And initialize the Grid and the ListView:
$("#grid").kendoGrid({
dataSource: ds,
columns :
[
{ field: "FirstName", width: 90, title: "First Name" },
{ field: "LastName", width: 200, title: "Last Name" },
{ field: "City", width: 200 }
]
});
$("#list").kendoListView({
dataSource: ds,
template : $("#template").html()
});
Now, what you should do is display one or the other depending on the width:
// Display Grid (and hide ListView)
$("#grid").removeClass("ob-hidden");
$("#list").addClass("ob-hidden");
// Display ListView (and hide Grid)
$("#grid").addClass("ob-hidden");
$("#list").removeClass("ob-hidden");
Where CSS class ob-hidden is:
.ob-hidden {
display: none;
visibility: hidden;
width: 1px;
}
Now, the only remaining question is invoke one or the other depending on the width. You can user jQuery resize event for detecting changes.
So, enclose both ListView and Grid in a DIV with id container:
<div id="container">
<div id="grid"></div>
<div id="list" class="ob-hidden"></div>
</div>
and define the resize handler as:
$("window").on("resize", function(e) {
var width = $("#container").width();
console.log(width);
if (width < 300) {
console.log("list");
$("#grid").addClass("ob-hidden");
$("#list").removeClass("ob-hidden");
} else { 
console.log("grid");
$("#grid").removeClass("ob-hidden");
$("#list").addClass("ob-hidden");
}
});
IMPORTANT: Whatever you do for getting this same result, please, don't create and destroy the Grid and the ListView each time there is a resize. This a computationally expensive operation.

Kendo grid populates under kendo tab strips

I don't see any examples of kendo grid with kendo tabstrips being done. Is that not possible?
As I tried kendo-tabstrip demo and kendo-grid demo. Both are working cool separately, but when I merge the code tabstrips are not showing properly.
I am successfully using a kendo grid inside of a tabstrip. The grid would not display inside of a tab unless I removed "<!DOCTYPE html>". If the DOCTYPE was present then the tab was always blank. I am not sure why that fixed the issue. What exactly do you mean by "not showing properly"?
Edit: I think my issue was actually caused when we had a splitter and grid inside of a tabstrip.
I was successful at adding a kendo grid inside a kendo tabstrip. After bringing in the required js files jquery-3.2.1/kendo.all.min.js, and the required css files kendo.common-bootstrap.min.css/kendo.black.min.css.
My Html
$(document).ready(function () {
$("#tabstrip").kendoTabStrip({
animation: {
open: {
effects: "fadeIn"
}
}
});
$("#grid1").kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Customers"
},
pageSize: 20
},
height: 550,
groupable: true,
sortable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [{
template: "<div class='customer-photo'" +
"style='background-image: url(../content/web/Customers/#:data.CustomerID#.jpg);'></div>" +
"<div class='customer-name'>#: ContactName #</div>",
field: "ContactName",
title: "Contact Name",
width: 240
}, {
field: "ContactTitle",
title: "Contact Title"
}, {
field: "CompanyName",
title: "Company Name"
}, {
field: "Country",
width: 150
}]
});
});
<div id="tabstrip">
<ul>
<li>Tab with Grid</li>
<li>Tab without Grid</li>
</ul>
<div>
<div id="grid1"></div>
</div>
<div>
<div>Normal content</div>
</div>
</div>
I did not have to remove <!DOCTYPE html>. Both the tabstrip and grid code was grabbed from kendo demos. here: https://demos.telerik.com/kendo-ui/tabstrip/index and here: https://demos.telerik.com/kendo-ui/grid/index

jquery ui dialog doesn't work with buttons

I'm trying to show a modal confirm dialog on delete link in a list action of a mvc 3 application.
<script language="javascript" type="text/javascript">
$(document).ready(function () {
$("#dialog-confirm").dialog({
autoOpen: false,
modal: true,
resizable: false,
height: 180
});
});
$(document).delegate(".deleteLink", "click", function (e) {
e.preventDefault();
alert('test');
var $link = $(this);
var $dialog = $('#dialog-confirm')
.dialog({
autoOpen: false,
modal: true,
resizable: false,
height: 180,
buttons: {
'button text': function () {
alert("button"); //this is the button, do something with it :)
}
}
});
$dialog.dialog('open');
});
<div id="dialog-confirm" title="Delete the item?" >
<p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>This item will be deleted. Are you sure?</p>
and this is the link
#Html.ActionLink("حذف", "Delete", "Need", new { id = item.NeedID }, new { #class = "deleteLink", title = "حذف" })
when i remove the buttons option it works but when i add it , it doesn't show up anymore
where i'm doing wrong?
At a very quick glance - it would seem that buttons is an array. Try pasting in the sample from the documentation:
... {
autoOpen: false,
modal: true,
resizable: false,
height: 180,
buttons: [ { text: "Ok", click: function() { $( this ).dialog( "close" ); } } ]
}

Foreignkey field get '[object object]' value when editRow with original field value is null

I have an issue that I use a dropdown list for my foreignkey field like demo : http://demos.kendoui.com/web/grid/foreignkeycolumn.html
The difference is that the foreignkey field in my model which can be null some time if it is not related to anyone else. Then the issue for me is when I try to editRow with this foreignkey field's original value is null, and I want to change to another value, this field will always get the value '[object object]'. I don't know why.
See the floor field in the following code:
<script>
$(document).ready(function() {
var template = kendo.template($("#detail_template").html());
function show_menu_details(menuObj) {
var tg = $("#details");
tg.fadeOut(function(){
tg.html(template(menuObj));
tw = tg.find(".k-window");
tw.css({width:tg.innerWidth()-30, height:tg.innerHeight()-55, "margin-top": 20, "margin-left":15});
});
tg.fadeIn();
}
$("#horizontal").kendoSplitter({
panes: [{collapsible: true, size: "180px"},
{ collapsible: true} ],
height: 690
});
function onChange(e){
e.preventDefault();
selectedObj = this.dataSource.getByUid(this.select().data('uid'))
//console.log(selectedObj);//(this.dataSource.data());
show_menu_details(selectedObj);
}
var statuses = [
{value:'', text:'--'},
{value:'Available', text:'Available'},
{value:'Locked', text:'Locked'},
{value:'Reserved', text:'Reserved'},
{value:'Occupied', text:'Occupied'}];
var floors = new Array();
floors[0]={text:'--',value:''};
_DS_Floor.fetch(function(data){
$.each(data.items,function(index,obj){
floors[index+1] = {text: obj.name, value: obj.id};
});
var grid = $("#list").kendoGrid({
dataSource: _DS_Room,
selectable: "row",
filterable: true,
columnMenu: true,
pageable: {refresh:true},
editable: {mode:"popup",confirmation:"Sure to delete?"},
height: 688,
scrollable: {
virtual: true
},
sortable: true,
toolbar: kendo.template($("#toolbar_template").html()),
columns: [//{field:'id',title:' ',width:40,template: '<input type="checkbox" id="#= id #" />'},
{field:'name',title:'Name'},
{field:'floor',title:'Floor',values:floors},
{field:'position',title:'Position'},
{field:'status',title:'Status',width:80,values:statuses}],//_Columns_Menu,//{ command: ['edit','destroy'], title: "", width: "200px" }
//change: onChange
});
grid.find("#btn-add").click(function(e){
e.preventDefault();
grid.data("kendoGrid").addRow();
});
grid.find("#btn-save").click(function(e){
e.preventDefault();
grid.data("kendoGrid").saveChanges();//editRow(grid.data("kendoGrid").select());
});
grid.find("#btn-remove").click(function(e){
e.preventDefault();
grid.data("kendoGrid").removeRow(grid.data("kendoGrid").select());
});
grid.find("#btn-cancel").click(function(e){
e.preventDefault();
grid.data("kendoGrid").cancelChanges();//removeRow(grid.data("kendoGrid").select());
});
});
});
</script>
Thanks.
Nullable values are not supported. Here is question from the KendoUI forums to which Vladimir Iliev provided explanation and solution. I hope this helps.
