Gauge RangePointer ignores binding after update to version 12.4451.0.24

[Steen Steiniche]

Hello Syncfusion

 

I have updated xamarin for Android to version 12.4451.0.24. I am trying to remove the error with multiple app icons on the phone. Now the gauge RangePointer has stopped working. It no longer updates when the model value changes. These lines used to work:

   

      

   var pointer = new RangePointer();

   pointer.SetBinding<LiveDataViewModel>(RangePointer.ValueProperty, m => m.Power);

 

where LiveDataViewModel is my model and m.Power is the value.

 

What must I do to have this working again?

 

Thanks in advance

Hi Steen,

Thanks for your interest in Syncfusion products.

We have already fixed the mentioned issue with "deploying two icons in android(Xamarin)", so there is no change need to be done from your end. The particular issue fix was already included in latest version "12.4.0.24" and RangePointer binding is also working fine in that version.  Could you please provide us simple issue reproducible sample, so that we could analyse on it and provide you better solution.

Please let us know, if you have any concerns.

Hello Joy

Thanks for your reply. I have attached a project that illustrates the problem. The gauge shows an initial value of a view model, but subsequent changes to the view model are not reflected. 

Hope to hear from you what I must do to make it work.

Thanks in advance

Steen

Hi Steen,

Thanks for your previous update.

The provided sample was really helpful for us to debug the mentioned issue. As the BindingContext were internally handled in CircularGauge control, we don't to set binding context separately for scale elements such as Ranges, pointers etc.

So the mentioned issue can be resolved by set the BindingContext for the CircularGauge control. For that please refer the below code snippet.

Code Snippet:

 

  SfCircularGauge g = new SfCircularGauge()

    {

       BindingContext = TestViewModel.Instance

    };

Please let us know, if you need any further assistance.
