I have an ESRI ascii raster and would like to get the raster values at defined x y locations. 
At the moment I am capable to load the Raster Dataset and can perform several operations like querying the  Min/Max values, the origin, the pixelsize and so on....

But is there a function to get the cell value of a raster at a certain location (x y)????

Has anybody done this before?
