WmsLayer reloads all tiles when panned

Question

Hi,

I'm using a WmsLayer as the basemap in my application. When I pan the map slightly to one side, the WmsLayer will reload all visible tiles, even though the large portion of the tiles have already been loaded. In other words: when I pan the map just slightly, all visible map tiles disappear and load over again. This differs from the behavior of and ArcGISTiledMapLayer, which will only load the tiles that have not already been loaded. Is there some way to get a similar behaviour in a WmsLayer?

btw. I'm using ArcGIS API for WPF version 2.4.

Cheers

*Yay* it's working now. Thanks dbroux! To be specific, the following did not work (i.e. no tiles are loaded): As soon as I added a ArcGISTiledMapServiceLayer, and then set the TileMatrixSet as below, it worked as a charm: My only issue now is that the loading time of the tiles seems to slow down at times (i.e. suddenly it takes up to 30 seconds to load a new set of tiles). This is a different issue however and I will try to debug it with Fiddler. Again thanks for your help dbroux!

I just tested with WPF 2.4 and that seems working as well (see screenshot).

What is your issue exactly?

Try to use fiddler to look at requests sent to the server, that might give a clue about your issue.

That's very strange indeed. When you got it to work, did you use Runtime 1.0?

I'm using version 2.4, and I cannot get it to work, even if I create a completely new project and copy/paste your code above into it.
