I just started to implement charting but run into an issue only after adding the required references as guided on page: http://docs.telerik.com/devtools/xamarin/controls/chart/getting-started/chart-getting-started-required-assemblies

When starting my application, OnCreate method in my MainActivity throws the following exception: Java.Lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.ContentFrameLayout.setId(int)' on a null object reference

I got DataForm controls up and running, but Chart control throws, even without writing a single line of code, only adding the references break my app. If I remove the references it will start to work again.

Any ideas what may be wrong?

Hi,

i have a Xamarin iOS chart that uses custom labels. My issue is the width of the Vertical axis labels: for a certain data set, the default vertical labels look like "0.22, 0.4599999999, 1.2999999999...."; when i set the custom labels to "0.1,  0.4, 5 ....", the width of the labels remains very big, just as if the large labels were still showing. The same thing happens if i set the range to something like "0.4599999999...." - the custom labels will have a lot of padding.

How can i force the labels to resize?

Thanks!

Hey everyone,

Does Xamarin Form Charts support negative chart values? (Especially -y axis) It says it does not supports for Xamarin forms but I'm not quite sure about this info. Does anybody knows? Thanks in advance.

ps. added sample chart to the attachment

Xamarin Mobile App Development: I am looking for help on how to force the top part of the device to adopt to a color that I want, when you look at the snapshot attached, top part of the device; the blue background is not what I want. I tried changing this color with failure. If anyone has an idea, please help.

Waiting for any helpful idea. Thanks.

I have successfully used the tooltip behaviour to get tooltips with the categorical and numerical values shown when a user taps on any of the bars within a bar chart series using Xamarin UI for Telerik charts.

Is there any way to format the presentation of these values ?

For example, prefix or append some fixed test to indicate the units.

Does this tie in with the LabelFormat ?

Separately but slightly related I've only been able to get LabelFormat set on the numerical axis.

Can the categorical axis values be formatted with a formatter in the XAML (or code behind?)

Hi,

I have downloaded trail version of Telerik UI for Xamarin.Android and playing around with examples I run in some problems with ListView I can't quite figure out.
In ListViewSwipeActionsThresholdsFragment.cs example clicking in left or right section of ListView activates "Hidden buttons" without swiping the view itself.

How do you prevent hidden button to fire up until they are actually shown by swiping the top layout?

Hi:

I tried to disabled the RadListView using the IsEnabled but this propety only works in iOS and not in Android.

The idea is to disabled clicking the cells while the control is being updated.

Any idea of what could be happening.

Thanks in advanced.

Hi:

When you display the calendar as a Month view and the user does a double click inside a day cell, the calendar changes the view to Year view.  Is there a way to disable or hide the Year view, so the user would never access to that view.

Thanks in advanced.
