I Have a large amount of data which had to the be overplayed on the map control. Since the topical data set consists of around 560 000 poly lines I have resulted in using Tiles to display the data so the map control doesn't slow down.
The problem I have is that since the user of the application is allowed to change the data which is used to generate the tiles I have be able to update loaded tiles or to force reload tiles.
At the present state the map control uses some internal chance for the tiles which results in :
if you move around the map while changing the data - some tiles are new and update some have old data present.
if you zoom out load old tiles if zoom in load the new tiles.
from the cache options i see that i can specify a folder but that doesn't effect the internal cached tiles which are used in the above scenarios.
is there a way to do the following:
Force reload on image tiles on specific layer (I have 2 the Bing map, and my custom one). The closes i have become to this effect was to move map center point so it requested some of the new tiles by some old(cached ones were used).
