I add datapoints to the RadChartView using CategoricalDataPoints. The values can be quite large and then I get the following error:

Value was either too large or too small for a decimal.

 

Then I did this test:

radChartView->Series[0]->DataPoints->Add(gcnew Telerik::Charting::CategoricalDataPoint(Decimal::ToDouble(Decimal::MaxValue), 0));

I still get the exception: Value was either too large or too small for a decimal.

 

What is the max value that can be set?

Hello, 

I was able to reproduce the error that causes System.OverflowException indicating that the value was either too large or too small for a decimal. The CategoricalDataPoint works with double values and is expected to work correctly with min/max values when converted to decimal.

Thank you so much for the response. Is there any work around for this? Do you perhaps know what the max and min values are so that I can limit the input so that the user does see that exception?

Hello,

Due to the specifics of the issue, I am not able to suggest a workaround. However, I would like to note that our developers are already working on this issue and we may introduce a fix when the testing is complete. When the fix is ready the CategoricalDataPoints should be able to accept decimal.Min/Max values. Make sure you have followed this feedback item in order to get notified when its status has changed. Please excuse us for the inconvenience caused. 

I hope this information is useful. Please let me know if you have any other questions.
