How do I get the selected template from the print dijit?

RyanClancy

I'm getting a list of templates from my Export Web Map task and putting them in the print dijit like in this sample. I want to record metrics about the usage of our print service and I want this to include which template the user selected for printing the map. However, it looks like the selected template is not a property of the print dijit. When I do something like this:

print.on("print-start", function(evt){
     console.dir(evt);
});

I do not see anything in the print dijit that gives me what I need. I can see the entire list of all available templates, but no way to tell which one the user selected. Anybody have any ideas?

Ryan,

You don't need to extend the print widget. Just add the setReqeustPreCallback to your app. Here's how you can test this.

1. View the print widget sample in the sandbox.

2. Paste the code below right after the line that sets the proxy then run the app and you should see an alert box with the selected print layout name each time you make a selection.

 

        esriRequest.setRequestPreCallback(function(ioArgs){
          if(ioArgs.url === "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task/execute"){
            alert(ioArgs.content.Layout_Template);
          }
          return ioArgs;
        });
