General sparklines question:

We're considering implementing sparklines in some of our forms, where we currently are implementing various DataViz charts (e.g. line, bar, area, etc.). One thing that's been pointed out is that we can implement spark lines in a way now by rendering a small regular chart configured without the axes or grid lines visible.

Besides some visual differences, are there any performance/overhead differences between sparklines and full charts? Or do they pretty much use the same engine for rendering?

Strange 500 error...

We are noticing a strange issue with a couple users who are using the Kendo upload. I don't really understand it and can't reproduce it outside of it being an issue on their PC when running as them. When they try to upload a file, they don't get any errors, but no file is uploaded. A 500 error gets reported in IIS logs, but nothing shows up in the event viewer. They don't even hit our event handler code that they are posting to. The IE developer tools show "(pending...)" for most of the columns when I look at the post in the network section. Uploading works fine for almost everyone else though, works as them from computers at other locations, and (the really crazy part) it works as another user at their location. The only browser they have is IE, and I don't have install rights to put anything else on their PCs. I'm not sure how much help I can get, since I can't really reproduce this issue, other than some very specific conditions. I thought I would post it here though, in case anyone had any ideas...

Update: One of the users has IE 10 without compatibility on. The other user with the issue has IE 9 with IE 7 compatibility on, and it had worked for her until some recent Microsoft update (not this month's patch Tuesday, before that). The upload control renders fine for both of them.

best practice for dealing with large varieted data sets

hey all
im new kendo so id like your opinion

id like to be able to show any of your charts
but in a very dynamic way
ie, if i have a UI area in which i can change params
the chart will respond in kind

would it be best to :

bring down a full data set in a datasource, have it in mem and just filter thru the data
refresh the datasource on every param click
do it some other way you guys have thought of thats way better

thanks!

truncated tooltip (bar\column chart)

Hello!

I've noticed that tooltip gets truncated (rather than getting correctly re-positioned to fit chart area).
Bar chart (see attach): tooltip for "long" bars gets truncated.
Column chart (see attach): tooltip for most right columns ALWAYS gets truncated.

Tooltips are super important for my scenario.
How can get this working properly?

Validation Design Impractical

The current design of your validators requires you to build the validator directly into the view. This information should instead be coming directly from the model and should be applied to the view via attributes applied by the model binding. Designing it the way you have causes a great deal more coding than would otherwise required with model binding. Is there any chance I can provide a speclet for how the validators should working using binding with the model to get this in the feature pipeline?

Disable DatePicker in Popup Edit screen from Kendo Grid

Hi, I'm using a Kendo Grid which has it's editable mode to popUp. When the edit screen pops up, all the fields from my model are displayed (this is what I want to happen). Many of the fields however, I want to be readonly (or disabled actually). I have an OnEdit method for the grid which is able to make many of the fields disabled, BUT the datepickers are still able to be clicked and the user is able to select a date from the popup calendar.

How can I make the Dropdowns truly disabled so they cannot be clicked to display calendar AND also LOOK disabled?? BTW using $("#AccountLockPeriod").data("kendoDatePicker").enable(false) does not work.

Here is my method:

<script>

function onEdit(e) {

$("#Id").attr("disabled", true);

$("#UserName").attr("disabled", true);

$("#AccountLockPeriod").attr("disabled", true);

$("#IncorrectLogonAttempts").attr("disabled", true);

$("#LastLogOn").attr("disabled", true);

$("#InactivateDate").attr("disabled", true);

$("#CreateDate").attr("disabled", true);

$("#LastUpdateDate").attr("disabled", true);

$("#RegistrationStatus").attr("disabled", true);

}

</script>

Order of itemchange event firing

I am trying to create a UI where I have a tree view on the left, and an edit form on the right that corresponds to the item selected in the tree view. I have attached my test page - it is stand alone. I am binding the edit form from the observableHierarchy change event. My problem is that when I have made a field edit in the form, and then select another item from the treeview, the itemchange events for the *selection* event are fired BEFORE the itemchange for the field data change. This causes me to re-bind the form BEFORE the field edit has been fired -- thereby losing the edit. If I click away from the form, all is well. Binding to the treeview select event does not help, as it fires before any of the observableHierarchy change events.

Can you suggest a better alternative to creating the desired UI? Is there some way to force the viewmodel update from within the select event?

Thanks,
Scott

Kendo Window appearing absurdly small.

Just updated Kendo UI scripts from Q2 914 to Q3 1114 and everything was working well until I tried to use the Kendo Window. It is currently appearing incredibly small and useless on the screen. Yet when you hit escape, the window appears to resize to the correct size before it vanishes.

Would like to know whats going on please.

Misspelled ListView option: "scrollTreshold" (aka "scrollThreshold")

I'm working with the ListView control and noted a misspelling of the word "threshold" in the option "scrollTreshold" (missing "h"). I first assumed it was a typo in the documentation, but quickly realized that the widget has it misspelled internally, so the incorrect spelling MUST be used.

This is minor, but has the potential to cause confusion as users will naturally try to spell "threshold" correctly (as I did). I suggest correcting the widget, but maintaining an alias for the misspelled version to avoid breaking existing code. You can specify the old spelling as 'deprecated' in the docs to warn users to update their code because you will eventually remove the alias in some future version.
