[Solved] Show and Hide the Tab Strip control

Hi there,

Is there a way to show an initially hidden tab strip and then hide it again?

I tried a number of ways (adding display: none and i tried adding visibility: hidden) but they only seems to work once and then break scrolling etc.

It's not possible for me to use different views with different layouts defined (With and without a tab strip) because I require it for the same view.

Thanks in advance!

Problems with column filters

I can add and apply the filter properly but when I click on the 'Clear' button for my column filter, it re fetch the data to the server (good) but keep the previous filters. It works only if I change for another selection.
My odata filter is look like this when I click on clear on the State filter column, the filter remains for that column.
$filter(YearSalesTarget ge 1000 and State eq 'nv')

I have tested with the new 2012.Q1 beta and I can't reproduced with the demo.
Maybe this is caused by the fact that I have overwritten the parameterMap?
How can I refresh the parameterMap properly? Any idea?

parameterMap: function(data,operation) {
                    if (operation == 'read') {
                    // Used default odata parameters
                    return kendo.data.transports["odata"].parameterMap(data,operation)
                    }
...
}

Grid memory leak?

I seem to be getting a memory leak on the grid widget. I pasted my code is below. In Firefox 12, when the application first runs up, Windows Task Manager says it is taking up around 60Mb of memory. If you click the add button, the memory used grows to around 85Mb, When you click the remove button, the memory does reduce a bit (after about 30 secs), but it only reduces to around 80Mb.

Is there leak in my code or kendo grid widget?

<!DOCTYPE html>

<html>

<head>

</head>

<body>

<div>

<button id="remove" value="remove">remove</button>

</div>

$(document).ready(function () {

$("#add").click(function () {

var data = [],

sharableDataSource,

i;

for (i = 0; i < 5000; i = i + 1) {

data.push({ field: "value " + i

});

}

sharableDataSource = new kendo.data.DataSource({ data: data });

$("#grid").kendoGrid({

groupable: false,

scrollable: true,

sortable: true,

pageable: false,

resizable: true,

selectable: "row",

dataSource: sharableDataSource,

columns: [{ field: "field", title: "field" }]

}).data("kendoGrid");

data = null;

sharableDataSource = null;

});

$("#remove").click(function () {

$("#grid").empty();

});

</script>

</body>

</html>

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"}]} });

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
