[GIS] Displaying scale on ArcGIS Engine map

arcgis-enginecwpf

I embedded ArcGIS Engine into a c#/wpf application and use it to display a map.
Now for print my client needs to display the scale of the map like it is used on street maps (the small bar which shows how long 500m are, and/or the scale information like 1:25000).

Prints are always on a set paper size like A4.

Is there a simple way to achieve this in an ArcGIS Engine application?

We made the layout in ArcMap and added a scalebar. In ArcGIS Engine we use the pagelayout to display a print preview and sent it to the printer. Not sure how this works in WPF but in winforms we used the sample for synchronize map and pagelayout to get started, but customized so we could open different layouts.

[GIS] Zooming & panning to selected objects using ArcGIS Engine

suppose you have just one Layer, with the selected features & you want to zoom to the extent of all the selected features, here is how I would do it:

IMapControl2 MapControl= (ImapControl2)_mapControl;
IfeatureLayer FeatureLayer=MapControl.Layer[0];

IFeatureSelection FeatureSelection= (IFeatureSelection)FeatureLayer;

ISelectionSet SelectionSet=FeatureSelection.selectionSet;

ICursor cursor;
SelectionSet.Search(Null, true, out cursor);

IFeatureCursor featureCursor = (IFeatureCursor)cursor; 


IFeature feature;
IEnvelope envelope = new ESRI.ArcGIS.Geometry.EnvelopeClass();

while ((feature = featureCursor.NextFeature()) != null)
      {
        IGeometry geometry = feature.Shape;
        IEnvelope featureExtent = geometry.Envelope;
        envelope.Union(featureExtent);
}

MapControl.Extent=envelope;

Try using the ControlsSelectFeaturesTool it works on features instead of ControlsSelectTool that work on graphics.
