I made a print widget for my webapp, which generates the print as pdf. I can change the title of the print figure, however, when I click the PDF and want to save it, the name of PDF file is something random, like "77ca24b763574b51ae868af8406fd267.pdf"!
I was wondering how can predefine the filename of ***.pdf?
The output name is originated from the REST service at:
There is a parameter Output_File and the name is from the Display Name. It is an auto generated name.
The best way is to use your ArcGIS server printing service and create your own print template. Then, you define the name of the pdf.
