Grid binding to JSON data resulted by ASP.NET Web API

Hi,

We are trying to bind the JSON data to grid using "Read" transport datasource. but somehow the grid does not show any record. The JSON data is valid and returned by ASP.NET Web API. If the JSON data is copied to ".JSON" file and provided to datasource, it works.

One of the strange part noticed, when the result is binding internally (guess), the grid throws an error. The error is "ParserError". Below is the code snippet. Please let me know any work around.

If the dataSource type is changed to "JSON", the error message is "No Transport".

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<title>Test Page</title>

<script src="js/jquery-1.7.1.min.js" type="text/javascript"></script>

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

<link href="styles/kendo.common.min.css" rel="stylesheet" />

<link href="styles/kendo.default.min.css" rel="stylesheet" />

<script src="js/json2.js"></script>

</head>

<body>

<div id="example" class="k-content">

<div id="grid"></div>

<input id="btnView" type="button" value="view" onclick="JavaScript: rebind();" />

<script>

function rebind() {

var gridDS = $("#grid").data("kendoGrid").dataSource;

gridDS.read();

}

$(document).ready(function () {

$("#grid").kendoGrid({

dataSource: {

type: "odata",

transport: {

read:"http://XYZ/JSON/Data",

contentType: "application/json; charset=utf-8",

type: "GET",

dataType: "json"

},

success: function (e) {

alert("Error: " + e.error);

},

schema: {

data: "Result"

},

error: function (e) {

debugger;

alert("Error: " + e.errorThrown);

},

change: function (e) {

alert("Change");

},

requestStart: function (e) {

//alert("Request Start");

},

pageSize: 10,

serverPaging: true,

serverFiltering: true,

serverSorting: true

},

height: 250,

filterable: true,

sortable: true,

pageable: true

});

</script>

</div>

</body>

</html>

Change Background of Selected Item in Drop Down

I cannot seem to find the CSS for the background color of the selected item in the Kendo ComboBox. Could anyone suggest how I could customize it? I'm attempting to change the Metro pallet and this is the only item that still shows green. Thanks!

donut chart layout collapses in IE7 (value < 1)

Hello guys,

I think I’ve found a bug in kendo’s donut chart in IE 7.
The problem occurs when the chart has a category whose value is less than 1 (e.g. 0.1). In that case the category appears in the middle of the donut chart.

Repro:

Do you know of any workaround?

Best regards,

'Kendo.Mvc.UI.Fluent.CrudOperationBuilder' does not contain a definition for 'Update'

Why would I get this on one of my grids with the same syntax, but another works fine.

Compiler Error Message: CS1061: 'Kendo.Mvc.UI.Fluent.CrudOperationBuilder' does not contain a definition for 'Update' and no extension method 'Update' accepting a first argument of type 'Kendo.Mvc.UI.Fluent.CrudOperationBuilder' could be found (are you missing a using directive or an assembly reference?)

Both grids specify:

.DataSource(dataSource => dataSource
.Ajax()

custom color dependent series label

Hi guys,

I'm using the colorField property to define different colors for each bar in my bar chart.
Is there any way to use the same custom colors as the series labels' text color.

e.g.
bar is red ==> the label next to it is red
bar is blue ==> the label next to it is blue

Kind regards,
ilo

bar chart + rgba color problem

Hello guys,

I have a problem with series border color when series color is defined as RGBA color.
In general border color is matching with series color. However if you use RGBA colors the border will be black no matter what color you used.

Repro:
http://jsfiddle.net/3v24W/1/

Any opinion?

Cheers,

Custom Edit, IE8, Razor, dropdown list only works once?

I'm using the "Editing custom editor" example to create a grid with multiple columns, few of which have dropdownlists for edits.

On Firefox, i can edit any of the columns that I have fine. However, with IE8, after editing a dropdown value once the column value shows up as "undefined".

has anyone else experienced this? And perhaps has a workaround?
