Printing Sample & MapUnits, Scalebar, etc

[LanceCrumbliss]

Hello All,

I've downloaded and compiled the latest print sample by dbroux. 

Using it, I noticed the print to scale functionality didn't work.  Poking around I noticed it was because the MapUnits was being detected as "Undefined" by the MapPrinter control.  Manually setting that to "Feet" in XAML resolved that. (The Projection is nothing weird, it's a state plane zone) However, two issue still remain:

• the scalebar on the printout just shows NaN.  I know what the means, but why?

• I cannot pan the map in the MapPrinterDialog window.  I can zoom in and out with the mouse wheel, but that's it.

I'm sure they're all related.

            <printing:MapPrinterDialog x:Name="MapPrinterDialog" Width="340" Height="405" Background="{x:Null}" Foreground="White" >
                <printing:MapPrinter x:Name="mapPrinterWithDialog" Map="{Binding ElementName=MyMap}" IsActive="{Binding ElementName=btnPrint, Path=IsChecked }" MapUnits="Feet" />
            </printing:MapPrinterDialog>

You likely need to set the 'MapUnit' property of the scalebar control, just as you did for the MapPrinter control.

I cannot pan the map in the MapPrinterDialog window. I can zoom in and out with the mouse wheel, but that's it.

Is there a scrollviewer in your visual tree that could catch the click events?
Try as well by removing the null background you set (Background="{x:Null}" ), this might be the reason the click events are not fired.

Ok, where...in the template of the MapPrinter control?  EDIT:  That's exactly where I changed it and the scalebar works now.

Unfortunately, changing the background color had no effect.  The MapPrinterDialog control is contained within a custom movable window control (like the "WindowPanel" user control in the Print Sample Project).  However, in our version, the ContentPresenter of that control is contained within a ScrollViewer.  So yes, I guess there is a ScrollViewer in the Visual Tree.  That may be the cause.  How can that be resolved (without removing the ScrollViewer from the equation)?

Got it working.  I created another template for the movable window that didn't have the ContentPresenter in a ScrollViewer and used that for the MapPrinterDialog's parent.
