Telerik Points have been updated for this report.
TextBlockElements are dynamic elements in the control and changing properties of such elements at design time is not allowed. Most likely the element you change the Alignment to is a default element which gets removed when the control is started. Still, we will look into a way to prevent this exception.
To modify TextBlockElements properrties, you can use the TextBlockFormatting event. More information is available here:

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
