Add or Remove Grid

Hi,
I'm trying to recreate the grid on this page every 30 seconds or so. What i do empty the div "grid-users" and do a call to the server. It returns me a JSON with the reconstructed table (but with updated rows), so I put it back inside the div.

The table shows find, but in the same setInterval block, once the table is back in the div, I try to make the grid and its controls on Kendo.

{% extends "saloons/templates/base.html" %}

{% from "ui/forms/macro.html" import wtform %}

{% block content %}

<form id="form1" method="POST" action="">

<br/><br/>

<div id="total" align="right">Total de pedidos en soles: S/.<div id="num" style="display:inline"></div></div>

<div id="fecha" align="left">Fecha: <input type="text" id="search_date" name="search_date" />

<button id="filter" name="filter" type="submit">Filtrar</button>

</div>

<br/><br/><br/><br/>

<div id="grid-users" class="grid-content" style="text-align: center; width: 100%!important">

<table id="grid">

<thead>

<tr>

<th data-field="number" style="text-align: center">Nro.</th>

});

}

$("#pedidos tr").each(function(i,v) {

$(this).find("td:eq(6)").children("select").kendoDropDownList();

});

},10000);

});

</script>

{% endblock %}

For some reason, the grid and the controls don't get to Kendo once the table is reconstructed. Can someone tell me why? Am I doing something wrong? =S

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".

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:
http://jsfiddle.net/ebD8M/2/

Do you know of any workaround?

Best regards,
ilo

'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,
ilo
