Missing label text from kendo donut chart when showing on kendo Window in Google chrome

In one of our requirement, we are showing kendo donut chart on kendo window. Kendo donut chart is rendering properly but its label are not getting placed at their correct coordinates( x, y) position.
When we investigated further, we found out that label tag(<text>) is forming perfectly but it is not getting placed at its desired position.

Is this issue occuring as we are showing kendo donut chart on kendo Window?
We are getting this issue on Google Chrome only.

Get Partial Checked item

Hi, I need to send back checked items in a hierarchical tree view and the state they're in. The state has to have 3 values, checked, unchecked and the "partial" check where only some children are checked (and the checkbox itself is "filled").

How do I get this state? I see no class, or anything that tells me it's partial (short of looking through it's child tree and looking for checked items, which I don't want to do).

Missing Popup in TypeScript definition

For the life of me, I cannot find kendoPopup() in the TypeScript definition file as either an extension to JQuery or as a class widget in kendo.ui.

Is this by design or an oversight?

Tooltip Problem - dataitem member undefined

It is pretty straight forward, there are plenty of references to using:

@(Html.Kendo().Chart(Model.oeeList)

.Name("widget-oee-breakdown")

.Theme("black")

.DataSource(ds => ds

.Group(group => group.Add(model => model.resp_id))

)

.Series(series =>

{

series.Column <double

?, string> (model => model.total, categoryExpression: model => model.area_name).Color("White").Name("Downtime").Labels(labels => labels.Visible(false).Format("{0:n2}")).Stack(true);

})

.ChartArea(ca => ca

.Background("transparent")

)

.CategoryAxis(axis => axis

.MajorGridLines(lines => lines.Visible(false))

.Labels(model => model.Rotation(90))

)

.Legend(legend => legend

.Visible(false)

)

.ValueAxis(axis => axis

.Numeric()

.Max(100)

.Line(line => line.Visible(false))

.MajorGridLines(lines => lines.Visible(false))

.Labels(false)

)

.Tooltip(tooltip => tooltip

.Visible(true)

.Template("#= dataItem.resp_name #: #= kendo.format('{0:n2}', value) #")

)

)

In this forum as well as others. "dataItem" doesn't return as undefined, but any member I specify does. In the example above I am using resp_name, which is in the data. Even if I try to use resp_id, which is what shows if I use series.name instead. Basically, anything I put after dataItem returns as undefined. Any ideas??

Adding an average line to an existing column chart

I've got a column chart with a single series. I am trying to add an average line to it. So, let's say the column chart has 5 data points [10, 20, 30, 20, 30] and shows 5 columns on the chart. The average is 22. Do I really need to have the average data be [22, 22, 22, 22, 22], which will put a circle for each data point on the line? Ideally, I'd like a single horizontal line across the chart without any data points showing up (while still having the data points on the columns show up so I can do hover). Hmmm, it would be nice to still have the hoverable capability on the average line so the user can see the exact value.
What are my options here?
Thanks,

Filter persists on reload of data

Hi,
Using the Kendo grid in Single Page Application using MVVM.
The filtering is only at client side, so when the user filters once on a column (say it has only one row) and then next reloads new data to the grid -the filter persists on the grid. It should ideally clear the filter off and reload fresh data without filters.
How is that possible (how to enforce it since it is not happening as expected)

Hi,

I am working with KendoUI Web widgets PanelBar:

var jsonStr = "[{text: " + "Item 1" + ",cssClass: " + "myClass" + ", url: " + "http://www.kendoui.com/" + "}]";
$("#panelbar").kendoPanelBar({
dataSource: jsonStr
});
});

but I am getting following error:
Error: Syntax error, unrecognized expression: [{text: Item 1,cssClass: myClass, url: http://www.kendoui.com/}]

I am using 2013.2.918.trial version.

Any help?

Strange "pseudo caching" or repetition in MutliSelect

I am using a Kendo MultiSelect for a "Tag Cloud" type thing. Tags look like this ... they are simple JSON.

{

Id: "tags/weapon",

Name: "Weapon",

Description: "This item qualifies as a weapon in the game."

},

{

Id: "tags/sword",

Name: "Sword",

Description: "This item qualifies as a sword in the game."

},

{

Id: "tags/shield",

Name: "Shield",

Description: "This item qualifies as a shield in the game."

}

The view model looks a lot like this ...

var viewModel = kendo.observable({

Id: null,

Name: null,

Consumable: false,

Equipable: false,

Tags: [],

});

The javascript to create the multi-select looks like this ...

var $tags = $("#tags").kendoMultiSelect({

dataTextField: "Name",

dataValueField: "Id",

itemTemplate: $('#editing-tags-template').html(),

dataSource: {

transport: {

read: {

dataType: "json",

url: url

}

},

open: function (e) {

this.list.addClass("k-tag-cloud");

},

close: function (e) {

}

}).data("kendoMultiSelect");

Where k-tag-cloud is a custom CSS style, this isn't giving me any trouble.

The HTML that this applies to is like this...

<select id="tags" multiple="multiple"

data-placeholder="Select Tags..."

class="dark k-tag-cloud"

data-bind="value: Tags"

style="width: 500px;"></select>

All of this works exactly as I expect. It appears like this on my screen, the behavior is normal, etc; I can select multiple tags, and when I save the item, they get saved without any extra code - just by being bound to the view model. If I retrieve an item, the tags list gets re-populated correctly with the selected tags.

However there is a template that is being used to draw the list to the screen in a different part of the page, that looks like this ..

<h2>Preview</h2>

<div style="border: dashed 2px black;">

<div style="padding: 8px;">

<h3 data-bind="text: Name" style="margin: auto;"></h3>

<h5 data-bind="visible: Equipable" style="margin: auto;">Equipable</h5>

<h5 data-bind="visible: Consumable" style="margin: auto;">Consumable</h5>

<div data-template="templates-admin-prototype-tags-preview" data-bind="source: Tags"></div>

</div>

And then this is the actual template that I call.

<script type="text/x-kendo-template" id="templates-admin-prototype-tags-preview">

<div class="k-prototype-tag">${ Name }</div>

</script>

Now what happens is that once a tag gets added, it draws to this section, but then it stays there - it will not "go away" if I remove the tag. So ..

If I start out and select "Weapon", the draw looks like this ..

Weapon

If I remove "Weapon", it removes it fine. But if I go above 1 tag ... it starts to repeat itself for each item. So if I select "Weapon" and then "Slashing", I get...

Weapon
Slashing
Weapon

This continues in infinite amounts, each time I add a new tag.
