I am using Sharpmap v 0.9 & ASPX.NET
My shapefile has several polygons in it. Each time a user clicks inside a polygon, the polygon should be
added to a selected set. All the polygons in the selected set should have a fill color of Red.
If the user selects an already selected polygon, the polygon should be removed from the selected set and the color should be rest back to the original color
I have the code to select a polygon working. Currently, when I click on the next poylgon, the 1st polygon is deselected & the the new polygon is selected. i.e I have not saved the set.
Does SharpMap have any built-in functions/samples to achieve this?
What will be a good approach to achieve this functionality?
