Quick question

The value of the variable ClimateDropDown is undefined in the following, which causes an error when I try to call ClimateDropDown.value(). The dropdownlist is created properly and gets initialized with the data from the remote data source.

              <input id="ClimateDropdown" />

            .......

            $("#ClimateDropdown").kendoDropDownList(
              {
                dataTextField: "Name",
                dataValueField: "NodeID",
                dataSource:
                {
                  transport:
                    {
                      read: "JSONClimateSpaceNodes.aspx",
                      dataType: "json"
                    }
                }
              }
            );

           ......

            var ClimateDropDown = $("#ClimateDropDown").data("kendoDropDownList");
            $.get("JSONIndoorClimate.aspx", "s=" + ClimateDropDown.value(), IndoorClimateResponse);

I am sure I am overlooking something simple and will appreciate a quick pointer to get me on the right track.

Thanks/Anker

Controls within a Grid using MVVM

I am trying to create a grid that has a row template with controls in them using MVVM. There are two problems I am struggling with:

1) It seems that the grid does not know how to deal with row templates that have controls in them.   There are several problems here:
     a) In IE, the column headers do not align with the rows, but it seems to work in Chrome.
     b) In both browsers, it does not seem to know what size the controls are and cannot properly size the grid.   The dropdowns get chopped, and the unfortunate part, is I need them to auto-size because I don't know in advance what the size of the dropdown will be.

2) I am not sure how to get the drop downs to use MVVM when inside of the grid.    The content of the dropdown needs to be bound to a property within the view model, not a property within the products list. Essentially, I do not want to embed within the products the list for each item.

See this fiddle for effectively what I am attempting to do:

Validate integer

Hi,

Is there build-in functions to validate integer vs decimal? Date format? Or do I need to use regular expression?
What about comparing 2 strings (equalTo)?

Thank you~

DropDown in Grid Toolbar does not appear to initialize

I have a Kendo Grid/Toolbar/Dropdown setup that is mostly inspired by the examples on the demo page.

It's a remote JSON backed grid (works fine), with a dropdown in the toolbar that is also backed by JSON (doesn't work fine).

What happens is the dropdown does not appear to initialize. It's not that it is empty and simply not loading data... but it's not even a kendo dropdown, it just remains as an empty input field.

If I take the exact template code, and javascript, and put it somewhere in an HTML file statically, it works great. Looks great, JSON binds perfectly, etc... but when I apply it to the toolbar using that template property, it just doesn't seem to work.

Here is my code...

Template Code:

<script type="text/x-kendo-template" id="template">

<div class="toolbar">

<label class="category-label" for="category">Show products by category:</label>

<input type="search" id="category" style="width: 230px"></input>

</div>

</script>

Grid and Dropdown JS:

var baseURL = "/Chargeability/JSON"

var dataSource = new kendo.data.DataSource({

transport: {

read: {

url: baseURL,

dataType: "json"

}

},

batch: false,

pageSize: 5,

serverPaging: true,

serverSorting: false,

schema: { data: "ChargeabilityWeeks", total: "TotalCount" }

});

var grid = $("#grid").kendoGrid({

dataSource: dataSource,

scrollable: false,

sortable: true,

columns:

[

{

title: 'Name',

field: 'Name',

template: '#= Name #'

},

{

title: 'Weekly Requirement',

field: 'Weekly_req_pct',

template: '#= kendo.toString(Weekly_req_pct, "p") #'

},

{

title: 'Weekly Actual',

field: 'Weekly_act_hrs',

template: '#= Weekly_act_hrs #'

},

{

title: 'Yearly Requirement',

field: 'Yearly_req_pct',

template: '#= kendo.toString(Yearly_req_pct, "p") #'

},

{

title: 'Yearly Actual',

field: 'Yearly_act_pct',

template: '#= kendo.toString(Yearly_act_pct, "p") #'

},

],

pageable: true,

toolbar: kendo.template($("#template").html())

});

console.log(grid.find("#category"));

var dropDown = grid.find("#category").kendoDropDownList({

dataTextField: "Name",

dataValueField: "ID",

autoBind: true,

optionLabel: "All",

dataSource: {

type: "json",

serverFiltering: false,

transport: {

read: '/Chargeability/BU_JSON'

}

});

Like I said if I just make some other input field outside of the grid and run this same code, no problem.

I did a test on the find() that is being run inside the grid and the result is NOT null... so... yeah. I'm kind of stuck at that point.

Pie Chart does not display with specific number

Hi,

I was trying to draw a pie chart which might container just one category, but with some specific value of that category, the pie chart does not display.

e.g. When I have this

series: [{

type: "pie"

	data: [ {

category: "Hydro"

		value: 312

	} ]

}]

It still shows the label but not the pie chart. If I change the value to 78, 156, 312... or 80.5, 161, 321, 322... and it stays the same.

Does anyone know how to fix this problem?

Thanks a lot in advance!

Functions aren't being executed in de datasource object initialisation...

I have this code in the datasource initiliation:
new kendo.data.DataSource({
                        type: "odata",
                        transport: {
                            read: {
                                url: crudServiceBaseUrl + "/GetBrokersFromEvent()",
                                dataType: "jsonp",
                                data: {
                                    id: $("#input").data("kendoComboBox").value(),
                                    userid: e.data.adres
                                }
                            },
                            update: {
                                url: function(data) {
                                    return crudServiceBaseUrl + "/Brokers(" + data.ID + ")";
                                }
                            }
                            ,
                            create: {
                                url: crudServiceBaseUrl + "/Brokers"
                            },
                            destroy: {
                                url: function (data) {
                                    return crudServiceBaseUrl + "/Brokers(" + data.ID + ")";

                                }
                            }
                        }

The functions won't be exe"cuted, but instead they will ben pasted in the request url????

fiddler:
GET http://localhost/Admin/function%20(data)%20%7B%20%20%20%20return%20crudServiceBaseUrl%20+%20%22/Brokers(%22%20+%20data.ID%20+%20%22)%22;%7D?%24format=json&%24inlinecount=allpages&models%5B0%5D%5B__metadata%5D%5Buri%5D=http%3A%2F%2Flocalhost%2FAdmin%2FServices%2F%2FService.svc%2FBrokers(1916463)&models%5B0%5D%5B__metadata%5D%5Btype%5D...

Grid sorting error

Hello,

I have a sortable grid that's bound to a kendo dataSource with the following transport configuration:

transport: {

read: {

url: "http://localhost/myJsonService",

dataType: "json",

},

parameterMap: kendo.data.transports.odata.parameterMap

}

Everything works fine when I'm sorting a column in ascending/descending order, but when I click on the column the third time (to disable sorting), the URL sent out towards the server is malformed : ...?%24format=json&%24inlinecount=allpages&%24top=5&%24orderby= which causes the server to fail.
This seems to be caused by the orderby= still being present, even though no sorting is applied. Is there any way of bypassing this without having to modify the sort function given in line 1542 of the unminified kendo.all.min.js not to assign the $orderby property when no actual data is present?

Listview Template - is there (possibly) a way of including JPlayer in a template?

Working on a basic application that recieves some records from a database which contain audio files. We've had the ability to display the records in a list view and we were able to include a Jplayer at the bottom (as a footer) playing a local music file. Is there a possibility of including the JPlayer inside of a template like so...

<script type="text/x-kendo-template" id="template">

<strong>${data.StartTime}</strong>

<strong>"Hello World"</strong>

</script>

The JPlayer is simply a div tag with a function that is called upon document being ready...

<div id="jquery_jplayer_1" class="jp-jplayer"></div>

<div class="jp-audio-container">

<div class="jp-audio">

<div class="jp-type-single">

<div id="jp_interface_1" class="jp-interface">

<ul class="jp-controls">
