Just starting out with Kendo and JSON and not having much luck in binding a grid to a json datasource. Here's my data, stored as a file called 'data.json' stored in the same directory as the page:

{
“firstName”: “John”,
“lastName”:”Smith”,
“department”:”Human Resources”
}

and my page:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Kendo1.aspx.vb" Inherits="KendoUI.Kendo1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <link href="Styles/kendo.common.min.css" rel="stylesheet" type="text/css" />
    <link href="Styles/kendo.default.min.css" rel="stylesheet" type="text/css" />
    <!--Then paste the following for Kendo UI Web scripts-->
    <script src="js/jquery.min.js" type="text/javascript"></script>
<script src="js/kendo.web.min.js" type="text/javascript"></script>
</head>
<body>
    <form id="form1" runat="server">
    <script type="text/javascript">
        $(document).ready(function () {

            var ds = new kendo.data.DataSource({
                transport: {
                    read: {
                        url: "data.JSON", dataType: "json"
                    }
                }
            });

            $("#grid").kendoGrid({
               dataSource: ds,
               columns: [
                    {
                        field: "firstName",
                        title: "First Name"
                    },
                    {
                        field: "lastName",
                        title: "Last Name"
                    }]
            });

        });

    </script>
    <div>
        <input id="myAutoComplete" />
    </div>
    <!-- Define the HTML div that will hold the Grid -->
    <div id="grid" style="width: 40%; margin: auto;">
    </div>
    </form>
</body>
</html>


Running the page just gives me the header row with the titles.

If anyone can point me in the right direction i'd be grateful.

Thanks

Hi, 

We do have a kendo scheduler bound to a remote data source.

The "transport" configuration of this scheduler's data source is done using remote urls (for CRUD), and this works perfectly,

On the server side, we make a lot of checks. So if some requirements are missing, Create, Update or event Destroy operations wouldn't pass and user will be shown the meaningful error.

The problem we're facing now is like the following :

For the Destroy action, what kind of response should we send back (from the server)  to the scheduler component (in the browser on the client side )  to prevent removal of events in the UI?

We've tried :

  • Sending back HTTP 500 status code
  • Putting an error field in the response and linking it to the schema.error configuration

But events are still removed from the UI, nevertheless the error event is fired. We even use this event to notify errors to end used.

Thank you.

I am using Kendo UI for JQuery and need to create a data-bound Kendo menu. By data bound, I mean that the items need to be data bound to an array property of a Kendo observable. The issue is that it appears that MVVM binding messes up formatting and functionality of the items. Here is my code (based on the example found in Kendo's documentation) :

 


<div id="example">
<div class="demo-section k-content">
    <div>
        <h4>Select an item</h4>
        <ul  data-role="menu"
            data-bind="events: { select: onSelect },
                        visible: isVisible"
            style="width: 100%;">
            <li>
                Products
                <ul data-template="menu-item-template" data-bind="source: items">
                </ul>
            </li>
        </ul>
    </div>
</div>

<script id="menu-item-template" type="text/x-kendo-template">
  <li data-bind="text: text"></li>
</script>

<script>
    var viewModel = kendo.observable({
        isVisible: true,
        items: ["Product1", "Product2", "Product3"],
        onSelect: function (e) {
            var text = $(e.item).children(".k-link").text();
            kendoConsole.log("event :: select(" + text + ")");
        }
    });
    kendo.bind($("#example"), viewModel);
</script>
<style>
    .demo-section .box-col li {
        margin-bottom: 0;
    }
</style>

The result of executing this code looks like this:

enter image description here

Notice how the formatting of the items is messed up (no margins, etc.).

 

Do you know what's the proper way to combine data binding and Kendo menu?

 

Thank you!

Hi, i have a grid which when creating an new element, the back-end verify if all the user data is correct and saves it in the db. Instead, if it have some errors will return which field has the error and the message about why failed.

My question is, how can i show this message like it was a validation? Like the required validation with the yellow tooltip above the cell (see image below)

My grid is in "inline" editing mode.

 

Thanks for your help!

How setup griid column in jquery.

I use this format, bit on input I get a date on the dropdown, not the time to chose

I need just the the time part, the date part is from "dataIni" field.

Another issue is the inline errors. I get error on field "hIni1" not on "Inicio 1"

                   $("#horarios").kendoGrid({
                        height: 550,
                        sortable: true,
                        pageable: true,
                        height: 550,
                        toolbar: [{ name: "create", text: "Inserir" }],
                        columns: [
                            { field: "dataIni", type: "date", format: "{0:yyyy-MM-dd}", title: "Data Inicio", width: "250px" },
                            { field: "hIni1", type: "date", format: "{0:HH:mm}", title: "Inicio 1", width: "120px" },
                            { field: "hFim1", type: "date", format: "{0:HH:mm}", title: "Fim 1", width: "120px" },
                            { field: "hIni2", type: "date", format: "{0:HH:mm}", title: "Inicio 2", width: "120px" },
                            { field: "hFim2", type: "date", format: "{0:HH:mm}", title: "Fim 2", width: "120px" },
                            { command: ["edit", "destroy"], title: "&nbsp;", width: "250px" }
                        ],
                        editable: "popup" // OR editable: { mode : "popup" }
                    });

Best regards

Sergio

Hey all,

I'm fairly new to kendo and have a bit of an problem ->

I'm currently troubleshooting a weird issue in version 2019.1.220.  I'd love to upgrade but its not feasible for this project at this time.

Basically, what is going on is that we're seeing some weird behavior with the Combobox control after databind.  Data comes from the database and is set in the control.  When the Arrow (Open button) is clicked its almost as though it doesn't do a read on the datasource because I get the No items found message.  However, if I change the selected text on the control it will do a pop open and locate the item in the list.

While trying to solve this with a work around I have tried to subscribe to the click event on the control and force a search function call in Kendo using the following:

    $(document).ready(function () {
        var itemCombo = $("#Items").data("kendoComboBox");
        itemCombo.input.on("click", function () {
            itemCombo.search(itemCombo.text);
        });
    });

This does seem to force a search to run on click of the control - however the arrow button on the control still does what it did before - not read the list or search for the item.  Does anyone have any quick tips on how i can access the click event on the arrow button itself?  The Open event isn't a good option - if I call .search on that it will cause an endless loop activity.

I'm sure this has been solved already in later versions but upgrade is not an option at this time.

Appreciative of any pointers!  Thanks!

Hi guys,

I've implemented virtualization over a dropdown which has a lot of items/rows (more than 3k) so I went with this approach. The issue now is that the dropdown always selects the first option no matter if i specify the value in any way. Any advices or any guide to fix this?

 

Best regards.

I am using the grid and need to be able to programmatically select a specific row based on the value of one field, and then scroll to that row if it isn't already visible. I can't find any way of doing that. If it matters, I'm not using paging. Is there a way to do this?
