When viewing a map in 2D mode, this property specifies the function that determines the correct file names for your tiles.
If you have created your own tile set and are using a tile naming convention other than the standard Bing Maps tile naming convention, you must create a function that returns the correct file names for your tiles. The GetTilePath property specifies this function.
|Custom tile naming is currently not supported in 3D map mode. This feature only works when the map mode is set to MapMode.2D.|
For more information about creating custom tiles and the standard naming convention, see Working with Tile Layers.
