UnsetValue error in SfChart3D


Using the 13.1451.0.21 version, I am trying to set the visibility of the numeric axis labels in a SfChart3D depending on their value. I am binding the Interval property in the ViewModel and I have created a converter for the LabelTemplate of the NumericalAxis.

The problem is that when debugging the converter, the expected values are shown, and then there are some unknown values and an "Unable to cast object of type 'MS.Internal.NamedObject' to type 'System.IConvertible'" exception is thrown, because the value of the internal has UnsetValue. Can you provide me with a solution?

I am attaching a sample which you can run to reproduce the problem.

Thanks in advance,

Hi Theodosia,

Thanks for contacting Syncfusion support.

We have analyzed your problem, it is a framework level problem. We have resolved it in an alternate way. Please change the binding as like in below code sample.


<Binding Source="{x:Reference columnChart}" Path="SecondaryAxis.Interval"/>
