I am trying to assign a classified renderer to a GdbRasterCatalog layer with no luck. I have examined the samples that are provided, but have not been able to make it behave.
I have developed code that allows a user to specify a date range, retrieve GRIDS falling within the range, build, and populate a GdbRasterCatalog, and add it to the ArcMap session. I was hoping the classification renderer assignment would be as straight forward as it is with a standard stand alone raster.
For the portion of the application that retrieves the stand alone GRIDS, it is pretty straight forward to assign an existing renderer derived from a .lyr file that contains the proper renderer classification definition. The GdbRasterCatalog apparently does not offer the option of assigning a renderer in that fashion.
Through the ArcMap interface, I am able to go through the process of adding the classified renderer type and removing the other non needed rendering types and building the appropriate classified renderer. I need to be able to do this programmatically through C#. I understand that the classification renderer is not one of the ???default??? renderers associated with the GDBRasterCatalog layer.
I have examined the IRasterCatalogRendererPicker bit, with no luck.
If need be, I can go through the effort of building the classified renderer directly from the catalog and abandon trying to use the renderer derived from the .lyr file. However, I still need to know how to assign the renderer to the GdbCatalog layer.
Any assistance would be greatly appreciated
