How to Use the New Memory Print Destination
If you only want to generate a report as a container, byte array or memory stream, in order to send it to a web service or to implement some other custom scenarios, you don’t have to use the File print destination. You can use the new Docentric print destination called Memory that enables printing report to a container (byte array or memory stream) using either the original built-in SSRS report design or one of the related Docentric designs (aka templates).
Print Customer Invoice to Memory
In the following example we are going to generate Customer Invoice using its default Docentric design (aka template) and save it to a memory stream or container using the Docentric Memory print destination.
