New Post: HOW TO make a different color for the selected polyline on the map

thx Koval , this worked

                    If fLayer IsNot Nothing Then
                        fLayer.SelectByAttribute("[YourAttributeInLayer] = '" & YourSearchValueOrStringInLayer & "'")
                    End If

and the selected items appear as lightblue ...

Could u give me a bit more info on how to adress its colr and linewidth? how to use MapLineLayer and SelectionSymbolizer ?

A code example would help a lot...
