| How to add click event for VB.Net ? We are have a vb.net app and are able to display a map with pushpins that represent the results from a sql server database query. This works fine. Now....I need to be able to let the user double-click on one of the pushpins and then display a modal dialog that contains some detailed info about the pushpin location. Is this possible? I saw some articles and posts that mention the SelectedChange event....but I am having problems getting this to work. If anyone knows of a good sample or article that would be appreciated. Thank you         |

Well, if you're looking to trap what they've selected, you can use the selection changed event like so: Code: Private Sub MapCtrl_SelectionChange(ByVal sender As Object, ByVal e As AxMapPoint._IMappointCtrlEvents_SelectionChangeEvent) Handles MapCtrl.SelectionChange
If TypeOf (e.pNewSelection) Is MapPoint.Pushpin Then
' A pushpin has been selected, get a reference to it
Dim pin As MapPoint.Pushpin = e.pNewSelection
' Call your method to display the box
Me.DisplayPinDetails(pin)
End If
End Sub
E.G. Code: Private Sub MapCtrl_DblClick(ByVal sender As Object, ByVal e As AxMapPoint._IMappointCtrlEvents_BeforeDblClickEvent) Handles MapCtrl.DoublClick
Dim searchResults As MapPoint.FindResults = Me.ActiveMap.ObjectsFromPoint(e.x, e.y)
Dim pin As MapPoint.Pushpin
For Each result As Object In searchResults
If TypeOf result Is MapPoint.Pushpin Then
pin = result
Exit For
End If
Next
' Call your method to display the box
Me.DisplayPinDetails(pin)
End Sub
BEWARE: This may cause your app to hang if your "DisplayPinDetails" method takes too long to run (I'm having problems along that line due to OleServer timeouts). Hope this helps. MR |
