I'm trying to customize a Map Printer Style from MapPrinterStyles.xaml. I've copied the basic style into my code and given it a key. It works fine when I remove this line of code below, but I would still like it to highlight the area to be printed. <controls:PrintOverviewLayer />
I end up getting the following error message. A value of type 'PrintOverviewLayer' cannot be added to a collection or dictionary of type 'LayerCollection'.
I've tried removing and adding the MapPrintingControls reference back from the sample, but I still get the same error.
I've tried running the workaround in the post below, but I'm still getting the same error message.
Likely there is a mismatch in the referenced dll's. Double check that your main project and the project withthe printing controls reference the same ESRI dll's.
