throw KeyUp event in MouseHover event in VB.NET - vb.net

Question

I am trying to capture a KeyUp event when the mouse is over the map. I am using GMaps library.
I have tried using the keypress, keydown and keyup events of my gmap control (where the map is placed), and I have tried to use the keypress, keydown and keyup from the form events, but nothing happens.
In my form, I have also some buttons, and what I see when I press one of the rows keys is that the focus is changing among the buttons, The effect is as if you wanted to select a button using the arrows on the keyboard, and I don't know why is doing that, if I have a specific code in the key events of the program.
In the MouveHover event I am using this code:
Private Sub GMapControl_MouseHover(sender As Object, e As EventArgs) Handles GMapControl.MouseHover
If Keys.Up <> Keys.None Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat + 1, GMapControl.Position.Lng)
End If
End Sub
But I have not the behavior I am looking for. Also I am trying to use the KeyUp event of the form:
Private Sub BMS_KeyUp(sender As Object, e As KeyEventArgs) Handles MyBase.KeyUp
If e.KeyCode.ToString = "Up" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat + 1, GMapControl.Position.Lng)
ElseIf e.KeyCode.ToString = "Down" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat - 1, GMapControl.Position.Lng)
ElseIf e.KeyCode.ToString = "Left" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat, GMapControl.Position.Lng - 1)
ElseIf e.KeyCode.ToString = "Right" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat, GMapControl.Position.Lng + 1)
End If
End Sub
Also I have tried the same in the KeyUp event of the GMap control:
Private Sub GMapControl_KeyUp(sender As Object, e As KeyEventArgs) Handles GMapControl.KeyUp
If e.KeyCode.ToString = "Up" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat + 1, GMapControl.Position.Lng)
ElseIf e.KeyCode.ToString = "Down" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat - 1, GMapControl.Position.Lng)
ElseIf e.KeyCode.ToString = "Left" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat, GMapControl.Position.Lng - 1)
ElseIf e.KeyCode.ToString = "Right" Then
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat, GMapControl.Position.Lng + 1)
End If
End Sub
And nothing...
Maybe someone has some ideas to do this?
Thanks!

Sorry, I have continued finding an answer and I have found the response of what I was looking for on this thread
https://social.msdn.microsoft.com/Forums/windows/en-US/ffeeea42-f6ba-420f-827e-74879fd29b26/how-to-detect-arrow-keys-in-vbnet?forum=winforms
By using the property:
Me.KeyPreview = True
In the Load method of the form, and using this code in the KeyUp of the form:
Private Sub BMS_KeyUp(sender As Object, e As KeyEventArgs) Handles MyBase.KeyUp
Select Case e.KeyCode
Case Keys.Right
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat, GMapControl.Position.Lng + 0.1)
e.Handled = True
Case Keys.Left
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat, GMapControl.Position.Lng - 0.1)
e.Handled = True
Case Keys.Up
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat + 0.1, GMapControl.Position.Lng)
e.Handled = True
Case Keys.Down
GMapControl.Position = New PointLatLng(GMapControl.Position.Lat - 0.1, GMapControl.Position.Lng)
e.Handled = True
End Select
End Sub
Anyway I would like to ask one thing I don't understand. I have tried this before but without using the Me.KeyPreview property, and without using the e.Handled = true property.
Could someone explain to me why using this two lines I have the behavior I want, and why without using them I was not able to do it?
Thanks!
