numericupdown detect down arrrow button for negative direction

click?

Right now I have;

Private Sub numericUpDown_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles numericUpDown.Click

Dim iValue As Integer

iValue = CInt(Me.numericUpDown.Value)

numericUpDown.Text = CStr(iValue)

How do I have it decrement and show negative numbers when clicking on the down arrow and then positive on the up arrow?

Thank you.

There is no need for your Click event, NUD does it automatically. To allow for negative numbers, set the Minimum property to a value less than zero.

Private Sub numericUpDown_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles numericUpDown_Speed.ValueChanged

Try

iNumericUpDownValue = Me.numericUpDown_Speed.Value

If iNumericUpDownValueOld > iNumericUpDownValue Then

iNumericUpDownValue = iNumericUpDownValue - 1

Else

iNumericUpDownValue = iNumericUpDownValue + 1

End If

LoadedTracks_ModifySpeedFactor(iNumericUpDownValue)

iNumericUpDownValueOld = iNumericUpDownValue

Catch ex As Exception

MessageBox.Show("numericUpDown_ValueChanged exception = " + ex.ToString)

End Try

End Sub
