You need to make sure that the ProcessingMode property is set to Local or Remote depending on where the report will be hosted. If you set it to Local, you need to set the LocalReport property, otherwise you need to use the ServerReport property when assigning the report to the control.

您需要确保ProcessingMode属性设置为Local或Remote，具体取决于托管报告的位置。如果将其设置为Local，则需要设置LocalReport属性，否则在将报告分配给控件时需要使用ServerReport属性。
