The problem is not getting the error via Dot Net programming, but the complete layout destruction of the report as a result of the fact that a picture (in our case a thumbnail of a provider) is unavailable. Catching the report error is not an option. It is too complicated and even if we succeed in obtaining the error, it will be very complicated to remove the unavailable url on the fly and re-render the report again. This seems to be a "known issue" for about 8 years! My question: Is it possible to keep the remaining report "intact" if such an error occurs? This shouldn't be too difficult for the development team..
