GoogleMap: Show/Hide Markers, Center Map, Address Not found

May 4, 2009 at 5:15 PM
Greetings!

First of all, congratulations for the great work.

I apologize if these issues have been already addressed in other topics, but I really didn't have the time to search thoroughly.

The problems I am trying to solve are:

1. Show/Hide Markers based on their title (sth like a category)
    This is the code I've been using, but it hides all markers and doesn't show them again.

    Public Sub ShowHideMarker(ByVal showMarker As Boolean, ByVal categoryTitle As String)
        Dim i As Integer
        Dim mrk As GoogleMarker

        With GoogleMap1
            For i = 0 To .Markers.Count - 1
                mrk = .Markers.Item(i)

                If mrk.Title = categoryTitle Then
                    If showMarker = True Then
                        mrk.Show()
                    Else
                        mrk.Hide()
                    End If
                End If
            Next
        End With
    End Sub

2. I can't seem to center the map so that all markers are shown. Autopan=True for each marker and I have enabled the MarkerManager.

3. How can I detect whether an address is found? I add the markers through a for loop and would like to produce an html table with each address and the status of the search (that is Found or Not Found)

Many thanks in advance!
