Public Methods

Method	Description
OnApplyTemplate ( ) : void	When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call M:System.Windows.Controls.Control.ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in an application.
ScaleBar ( ) : System	Initializes a new instance of the ScaleBar class.

Private Methods

Method	Description
GetBestEstimateOfValue ( double resolution, ScaleBarUnit displayUnit, ScaleBarUnit &unit, double &outResolution ) : double
GetResolutionForGeographic ( MapPoint center, double resolution ) : double	Calculates horizontal scale at center of extent for geographic / Plate Carrée projection. Horizontal scale is 0 at the poles.
OnMapPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
RefreshScalebar ( ) : void	Refreshes the scalebar when the map extent changes.
RoundToSignificant ( double value, double resolution ) : double	Rounds to a value to the significant number of digits.
getBestEstimateOfValue ( double resolution, ESRI displayUnit, ESRI &unit, double &outResolution ) : double
getResolutionForGeographic ( ESRI extent, double resolution ) : double
map_ExtentChanged ( object sender, ESRI args ) : void	Handles the ExtentChanged and ExtentChanging event of the map control.
refreshScalebar ( ) : void
roundToSignificant ( double value, double resolution ) : double
