Hi Arnd...
I have some questions about that...
First I have a geo app using Openlayers/Mapserver WMS with SDE layers....
My application has a treeview with all layers, and a radiobox for each
layer... When I click in a layer´s radiobox a window with a GRID containing
all layer´s data is opened...
In that GRID, When I select a line (layer´s data), the Map should :
1-) Highlight it
2-) Zoom in data selected
Can I develope that using SLD and SLD_BODY ? Do you have any tip to how do
that?
Thanks
