Hi,

We are using Xamarin forms controls of telerik UI for Xamarin.

Bar series in Charts is not rendering it's bars in iOS. This is a case where I first bind chart to a collection with Zero Values(for Numberic Axis) and change data of values to Non-Zero values, then it does not redraw Bars but it shows labels (data points) with updated numbers/values.

In other case, i.e., bind chart to collection with Non-zero values first then change to zero values, works fine.

I am able to reproduce this with your samples (SDKBrowser). Is there any way to force redraw bars??

Thanks,

How can i render a picker in dataform. PFA

I have checked the sample code but the items of picker are harcoded in it. 

In my case, the  data source or items for picker is coming from a web API. How can i bind the data to this kind of picker

Hi

I am trying to create a dynamic dataform with dynamic questions, using a json retrieved from a database.

These questions can be different types (text, int, picker, date, etc.).

As far as i understand the only data source you can assign to the dataform is a class of type NotifyPropertyChangedBase. Each property declared in the class is a question in the dataform. 

How can i dynamically create these properties and set the proper editor based on the type? The json contains the question text and type (among other things but they are not relevant for my problem).

Thanks for any advice!

I am wondering if anyone has seen behavior like this.

I am using MVVM and Prism as well.

Everything appears totally fine and the Provider gives the list of items to select from and works perfectly ... on the first selection.

The remaining selections do not update the form (Set is never called).

If you force a page refresh (change device orientation) everything updates correctly, set is called and you are good again ... for ONE selection.

Then you are back in the same boat.

Any help appreciated.

I am not able to find any control for xamarin forms which can be used to browse file and select one or multiple files from device. 

Please let me know if i am missing something or there is some approach so that i can browse and select file?

I m using rad calendar and have a button outside where i fetch the events and i want to set them in the calendar. On the click I have fetch the events and set them to the AppointmentsSource of the calendar. But the calendar view does not seem to get updated, so the events not visible in the calendar. 

I can see the events are set to the AppointmentsSource but not visible in the view.

how to solve this. 

Thank you,

I have a subclass of RadCalender which has an additional collection of items, which I'm binding to the calendar using a custom cell.

So, I have two issues...

1. How do I asynchronously bind this additional collection to the calendar? (The data comes from a web service.)

2. How do I reload the data when it's changed?
