Thank you for writing.
To reload the data from the database, you should use the Fill method of your table adapters to repopulate your datasets with data. When you do this, RadScheduler
should automatically detect the changes and reflect them to the user interface. If this does not happen, then you can force an update by calling RadScheduler
I hope you find this useful. Feel free to ask if you have any additional questions.
All the best,
