narrowRange ignored when a datapoint is null?

Hi there I have a line chart with grouped data and narrowRange: true set.

When one of my datapoints has a null value it seems that narrow range is ignored. Folks are choosing series from a dropdown and when one series has a null the scale changes suddenly which isn't ideal.

Here is a fiddle with all datapoints for each line and narrowRange working well- http://jsfiddle.net/jriley17/vDdmt/
and here is one with a null value for one of the points - http://jsfiddle.net/jriley17/j83Sk/

thanks!

e.dataItem on Grid DataBound

I have following code and I am getting e.dataItem as undefined. Is there a way to get access to dataItem and its properties at client using JavaScript?

Html.Kendo().Grid<AdminReport>()

.Name("AdminReportList")

.Columns(c =>

{

c.Bound(r => r.Name).Title("Report Name").Width(50);

c.Bound(r => r.Id).Title(action).Width(230).Sortable(false).Filterable(false)

})

.Pageable(p => p.PreviousNext(true))

.Sortable()

.Filterable()

.Events(e => e.DataBound("onRowBound"))

.DataSource(d => d

.Ajax()

.Model(m => m.Id(r => r.Id))

.Read(read => read.Action("_ListAllReports", "AdminReports"))

.Events(e => e.Error("OnError")))

.Render();

function onRowBound(e) {

if ((e.dataItem.SomeProperty === true)) {

//Some code...

}

Rendering or Appending a View in a Container

Reading http://docs.kendoui.com/getting-started/framework/spa/view I understand that the "render" method renders a view inside a container by replacing the current content with the new content.

However, when testing, I did not see that behaviour. Actually on "render" the view is appended to the current content, inside the wrapping "div" element.

SPA without the P

Our page contains complex "Widgets" and each widget might have multiple views, and we're using MVVM for the data.

I'm wondering (and I've seen posts eluding to this) if I can scrap the url routing portion and just be able to define views for each widget?...I'm concerned with the routes in the url and multiple widgets all getting confused and\or creating a terrible url. Really nobody would be going "back", bookmarking, or linking anyway.

If this is possible, is there a demo\sample anywhere?

Changing the grid row height with jquery not working

I am trying to edit the grid height with a bit of jquery and binding.
It does not appear to work.
I can do the colours and the font, but the height does not want to budge.
Below is my test on fiddle.

Anyone know how to fix that?

Editor template if statements

In my grids I have partials views as my editor templates. In the these editor templates I try to check the values on create and edit using razor if statements. These statements do not seem to work for grid editor templates. Here is an example
@if(Model.UserName!=null)
{
@Html.LabelFor(m=>m.Username)
}
else
{
@Html.TextBoxFor(m=>m.UserName)
}

The if always seems to fail is this because after the template is rendered these statements are no longer there and cannot be reached?

Is the only way to accomplish my task is by altering these elements via jquery in the grid edit event?

Model object's Dirty Attribute is not Observable

I am trying to change the "save" icon on my edit form when an item is flagged dirty as a visual reminder to the user to save her/his work. However it does not appear as though the "dirty" attribute of the Model object is observable. Its value never changes in the UI when I bind to it nor does it ever notify when I bind to the "change" event.

I know that I can do what I want by binding to "change" but it seems silly to have to observe the entire object and have an event that fires with every change and for any change when a property already exists that purports to contain the desired information that I am after.

Or am I just missing something?

kendo duplicate rendering issue

a long time ago we modified the kendostore front sample for our internal needs.

specifically store-browse.js

(function ($, kendo, store) {
    var viewModel = kendo.observable({
        Products: {
            data: [],
            total: 0
        },

noticed data is array not DataSource or ObservableArray
- changing to DataSource throws a recursion error in kendo js file
- ObservableArray works but suffers from duplicate rendering issue

About: kendo duplicate rendering issue

<section>

<div class="clearfix" data-role="listView" data-bind="source: Products.data" data-template="product-template"></div>

</section>

attached is image where left side is code causes duplicate rendering randomly.

my hack so i wouldn't have to do major refactoring is on the right . (working - no more doubles)

Can someone explain why doubles happen when pushing into array (left side of code)?
