Grid Sample

Hi,

Trying to get the basic Grid sample to work. Getting the following errors...

SCRIPT5007: Object expected
kendo.all.min.js, line 1 character 13464
SCRIPT438: Object doesn't support property or method 'kendoGrid'
index.html, line 19 character 2

Here is my HTML - any help is appreciated as I'm sure it is a basic, newbie mistake.

<html>

<head>

<title>Test Kendo</title>

<link href="../js/kendo.common.min.css" rel="stylesheet" type="text/css" />

<link href="../js/kendo.kendo.min.css" rel="stylesheet" type="text/css" />

<script type="text/javascript" src="jquery-1.2.6.min.js"></script>

<script type="text/javascript" src="js/kendo.all.min.js"></script>

</head>

<body>

<div id="grid">

</div>

<script type="text/javascript">

$("#grid").kendoGrid({ columns: [{ field: "FirstName", title: "First Name" }, { field: "LastName", title: "Last Name"}], dataSource: { data: [{ FirstName: "Joe", LastName: "Smith" }, { FirstName: "Jane", LastName: "Smith"}]} });

</script>

</body>

</html>

Line Series - Break Line

I have a requirement that if the series type of line hits 0 to break the line and continue once the series has another value above 0.

Is this possible? Can I hide certain data points?

Let me know if a visual would help.

Dates on the category axis of line chart

Is there some way that I can get DataViz to automatically generate a nice looking axis when using dates on the category axis? It would be helpful if it for instance could choose an appropriate step size etc. automatically.

If this isn't possible I have another question. How do I make it step over some ticks cause I only want ticks where I have labels.

Thanks

MVVM with Single Entity from Remote Server

Every sample I can find works on the premise of multiple rows of data coming back.

In our case there is only one row being returned because this is a single item edit screen.

I have a Web API request that returns an object. Here's the response from the call:

{
"FirstName": "James",
"LastOrCompanyName": "Hancock",
"MiddleName": "Robert",
"Salutation": "Mr.",
"Suffix": null,
"Individual": true,
<...more fields...>
}

It's formatted exactly like that with Json.

What I'm attempting to do is put text boxes that allow edit of those values.

Here's what I have:

var Contact = kendo.data.Model.define({
ID: "ID"
});

dataSource = new kendo.data.DataSource({
type: "json", // specifies data protocol
transport: {
read: { url: "/api/v1/contacts/GetContactByID?id=" + ContactID },
},
schema: {
model: {
id: "ID"
}
},
change: function (e) {
selectedContact = e;
},
error: function (e) {
debugger;
}
});

var viewModel = kendo.observable({
dataSource: dataSource,
hasChanges: false,
change: function () {
this.set("hasChanges", true);
}
});

kendo.bind($("#contact-info"), viewModel);

for sake of argument I also bound a grid to the datasource like so:

$("#g-contact-info").kendoGrid({
groupable: true,
scrollable: { virtual: true },
sortable: true,
pageable: true,
dataSource: dataSource
});

The grid doesn't display any data even though one item came back.

And I can't figure out any way to logically set the observable to the first item even if it did. I was expecting some sort of data control on the observable that allowed you to change which is the current item just like a BindingSource in Winforms or something.

Can someone help with the two issues? First being the data not coming back and binding properly, the second being how do I get the observable to set properly and get my selectedContact set with the right value.

Thanks!

'sum is not defined' error on grid

Hi ,
I am developing an application using kendoui grid,and i am facing a problem
when grouping the records according to different columns.
I want to have records grouped by name column and at the same time have footerTemplate and groupFooterTemplate for quantity column.
When i add another column on grouping i get an error 'sum is not defined'.
I have looked around on kendo forums, and even the following forum topic:
http://www.kendoui.com/forums/ui/grid/groupable-aggregates-and-groupfootertemplate-problems.aspx

doesn't resolve me the problem.(which looks me more similar to my problem).
I am putting the columns,group,aggregates and fields using php variables:
$arr=array(array('field'=>'pol','title'=>'Part Number','width'=>'200px','aggregates'=> "count", 'groupHeaderTemplate'=> "Part Number: #=value#"),
array('field'=>'name','title'=>'PO ','aggregates'=> "count", 'groupHeaderTemplate'=> "PO Teknema: #=value#"),
array('field'=>'po_supp','title'=>'PO Supplier','aggregates'=> "count", 'groupHeaderTemplate'=> "PO Supplier: #=value#"),
array('field'=>'seltc','title'=>'Quantity Received','aggregates'=> "count", 'groupHeaderTemplate'=> "Quantity Received: #=value#"),
array('field'=>'pol_qty','title'=>'Qty to Receive','aggregates'=> "sum", 'footerTemplate'=> "Total Sum: #=sum#",'groupFooterTemplate'=> "Sum: #=sum#" ),
array('field'=>'qty_purchased','title'=>'Total Qty','aggregates'=> "count", 'groupHeaderTemplate'=> "Total Qty: #=value#"),
//array('field'=>'prod_name','title'=>'Part Number'),
array('field'=>'rif_ordine','title'=>'Rif.Ordine','aggregates'=> "count", 'groupHeaderTemplate'=> "Rif.Ordine: #=value#"),
array('field'=>'project','title'=>'Project','aggregates'=> "count", 'groupHeaderTemplate'=> "Project: #=value#"),
array('field'=>'po_ref','title'=>'PO Reference','aggregates'=> "count", 'groupHeaderTemplate'=> "PO Reference: #=value#"),
);
$columns=json_encode($arr);
$arr=array(
'pol'=>array('type'=>'string'),
'name'=>array('type'=>'string'),
'po_supp'=>array('type'=>'string'),
'seltc'=>array('type'=>'string'),
'pol_qty'=>array('type'=>'number'),
'qty_purchased'=>array('type'=>'number'),
//'prod_name'=>array('type'=>'string'),
'rif_ordine'=>array('type'=>'string'),
'project'=>array('type'=>'string'),
'po_ref'=>array('type'=>'string'),
);
$fields=json_encode($arr);
$arr=array('field'=>'name',
'aggregates'=>array(
array('field'=>'pol','aggregate'=>'count'),
array('field'=>'name','aggregate'=>'count'),
array('field'=>'po_supp','aggregate'=>'count'),
array('field'=>'seltc','aggregate'=>'count'),
array('field'=>'pol_qty','aggregate'=>'sum'),
array('field'=>'qty_purchased','aggregate'=>'count'),
array('field'=>'rif_ordine','aggregate'=>'count'),
array('field'=>'project','aggregate'=>'count'),
array('field'=>'po_ref','aggregate'=>'count'),
)
);
$group=json_encode($arr);
$arr=array(
array('field'=>'pol','aggregate'=>'count'),
array('field'=>'po_supp','aggregate'=>'count'),
array('field'=>'seltc','aggregate'=>'count'),
array('field'=>'pol_qty','aggregate'=>'sum'),
array('field'=>'qty_purchased','aggregate'=>'count'),
array('field'=>'rif_ordine','aggregate'=>'count'),
array('field'=>'project','aggregate'=>'count'),
array('field'=>'po_ref','aggregate'=>'count'),
);
$aggregate=json_encode($arr);

and then pass these variables on js

Please Help me to solve the problem.
Thanks in advance

Declarative Bindings Uniform Implementation/Documentation

We need uniform implementation and dedicated documentation similar to "Configuration" that describes how to declaratively bind controls. I'm having to do a lot of repetitive coding for binding that should be a simple declarative structure. You should be able to enable a property on your kendo framework and request it to declaratively data bind and off you go.  Very little coding necessary. For example:

<input id="siteList" class="ctrlDropDown" data-template="#siteListTemplate" data-dataurl="Layout/sites.json" data-selector="sites" />

    $(".ctrlDropDown")
    .each(function (index, htmlControl) {
        var control = $(htmlControl);
        var dataSourceUrl = control.attr("data-dataurl");
        //alert(dataSourceUrl);
        var dataSourceCallback = control.attr("data-datacallback");
        var template = control.attr("data-template");
        var dataType = control.attr("data-type");
        var dataText = control.attr("data-text");
        var dataValue = control.attr("data-value");
        var dataSelector = control.attr("data-selector");
        //alert(dataSelector);
        var dataSource = new kendo.data.DataSource({
            type: (dataType != null) ? dataType : null,
            transport: {
                read: {
                    url: dataSourceUrl,
                    jsonpCallback: (dataSourceCallback != null) ? dataSourceCallback : ""
                }
            }
        });
        dataSource.fetch(function (data) {
            //alert(JSON.stringify(data.sender._pristine));
            control.kendoDropDownList({
                autoBind: true,
                dataTextField: dataText,
                dataValueField: (dataValue != null) ? dataValue : dataText,
                template: (template != null) ? kendo.template($(template).html()) : null,
                dataSource: (dataSelector != null) ? eval("data.sender._pristine." + dataSelector) : data.sender._pristine
            });
        });
    });

Splitview on Trial Version is not available?

Hi all,

I'm looking at the splitview demo on this link http://demos.kendoui.com/beta/mobile/splitview/index.html and I try to create the prototype using its demo source code with kendo trial version, but I think the data-role 'splitview' and 'pane' didn't work well. Can anyone help me, please? Or this feature is available for only the licensing version?

Thanks
