Declaration
public Location GeoBoundsSE { get; set; }
Property Value
Location

Remarks

You can't use this property to set bounds at the same time with GeoBounds property.

Declaration
protected Dictionary<string, IMapSource> MapSources { get; }
Property Value
System.Collections.Generic.Dictionary<System.String, IMapSource>

Opacity

Gets or sets the opacity factor.

Declaration
public double Opacity { get; set; }
Property Value
System.Double

SpatialReference

Gets spatial reference of the current map source.

Apply map source modes.

Declaration
protected virtual string ApplySourceModes(string uniqueId)
Parameters
System.String uniqueId

Base source unique ID.
Returns
System.String

Unique ID of the map source with applied modes.
Remarks

Some providers (Bing, for example) can have different modes for the same base source (arial with/without labels in Bing, for example). This method allows apply this kind of modes to the base source.

CreateInstanceCore()
