custom TiledMapServiceLayer documentation or help!!

DmitryAleshkovsky — Fri, 12 Nov 2010 08:09:43 GMT

Where can i get good documentation about implementation of TiledMapServiceLayer/TiledLayer?
I need to add tiledlayer from my own URL and from tiles in WorldMercator projection(WKID = 54004).
a few questions:
1/Is it possible combine in the map tiled layers with different projection (WebMercator 102113 and WorldMercator 54004)?
2/what is the Origin property in the TileInfo?
3/ if I create function
public override string GetTileUrl(int level, int row, int col){}
where are parameters(level,row,col) come from? From the ESRI map in WebMercator projection?
so I must recalculate them in my row,col values?

This sample might be a little outdated but hopefully it can help you get started:

The following links can also be retrieved from API Reference in the SDK sample page (http://esriurl.com/slsdk2

Thank you, Jennifer!
I know this links, but I can't get answer for my questions there :confused:
the main question is about possibility to have 2 tiled layers in the map with different coordinate systems - WorldMercator and Web Mercator.

Different SpatialReference will not work because the projection of the Map is determined by the first visible layer with a SpatialReference defined. If the SpatialReference of the Map is different than a Tiled Layer, the Tiled Layer will not be displayed.
