  Cause:
  The error message "Cannot dismiss control &1; only blocking type control can be dismissed" suggests that the control you are trying to dismiss is not of the type that can be dismissed.

  Use Correct Methods: Make sure you are using the appropriate methods for dismissing controls. For example, if you are using a modal dialog, ensure that you are calling the correct method to close it.
  
  
  Debugging: If you are unable to identify the issue, consider using debugging tools to trace the execution flow and see where the error is being triggered. This can help you pinpoint the exact control and the context in which the error occurs.
