Re: Grid map example in C#
Hi,
I've posted this example in response to a specific query about how to create a grid map image for a website using .NET. I've written it in c#, it is not polished, but does show the priciples of how to set year filters, colours, etc. I've included an image of what the form looks like when I use it specifying the key for Water Vole (NHMSYS0000080205). The code beneath the image is a full dump of GridMapQuery.cs file showing all the auto-generated code too, so just pick out anything that is useful.
