Questions on Kendo UI for jQuery Forum

Hi,
I am trying to replicate chart coloring similar to what can be seen in the following screenshot, where the starting color is blue and the end color is red. No matter how many data points are in between an equal gradient will be formed - this is done dynamically and can be applied to a chart with X number of bars.

Is this possible? I am using seriesColors at the moment but they don't automatically spread the gradient across the chart. If for example there are only 2 bars on a chart, one will show blue and the other red.

Hope this was explained ok, I do not want to hard-code seriessColors for each chart as these graphs are being displayed dynamically from a datasource.

Thanks,
Andrew.

Virtual scrolling with datasource paging unstable

Hello,

I'm using a kendo grid with scrollable: { virtual: true } with a kendo datasource with serverPaging.
This works fine when the grid is only used to read data, but i'm experiencing strange effects with CRUD operations on the datasource.
Especially when a datasource.cancelChanges() is called when the grid is on another page then the first page.
When I edit any of the model fields and decide to cancel the changes this is what happens:
- the Model.set has been called due to leaving the input (blur event)
- dataSource.cancelChanges will be called.
- dataSource jumps to first page.

Side effects:
- page data is out of sync and doesn't show the first row anymore.

It even gets weirder when I use dataSource.cancelChanges(myModel) when i'm on another page then the first page.
The entire row disappears from the grid which leaves the grid showing 14 rows instead of 15 (pageSize).

All in all the whole paging mechanism appears to be extremely buggy in a real world application (including CRUD operations.. etc)

navigator question

Is the navigator in the stock chart demo only available for the stock chart? If so is there any limitation of the stock chart that will prevent it from working with other time series based data (I am interested in the line chart)?

Thanks,

Jason

Need help with autoComplete grid functionality

So I've been working on an autocomplete for a state grid field. Everything (for the most part) works fine, accept for about half the states
will display [object Object].

For example, if you add a new record and select New Hampshire as your state it will return [object Object]

Any help would be greatly appreciated!

Vertically very small search bar, how to change?

Hi,

this is perhaps a simple matter, I would like to ensure the search bar is a lot easier to hit with my fingers. This renders really nicely (e.g. larger) on iOS 6 but as soon as I put this onto iOS 7 it's tiny.

I'd like to increase it's vertical height.

here's a picture of what the search bar looks like on iOS7: https://www.evernote.com/shard/s7/sh/e254e198-74f4-473a-8148-50f6bd879988/b5dd6c1a37393840b9df3d45c82620a1/deep/0/Screen%20Shot%202013-09-26%20at%2015.30.38.png

Thanks.
