We have introduced a fix in the RadTileView
for a few reported scenarios in which this exception used to come up. However, I am not sure if this fix will work for you as I am not sure if you're using the RadTileView
This is why, if you believe that the issue is related to the RadChart
control, you can start a new thread targeting the RadChart
control and elaborating on the issue you have with it. A sample solution will also greatly help us to better understand the case and the cause for the exception.
