  Hi!
  
  I've been having trouble with the maskededitbox valuechanged event. Please check the following example:
  
  

  Private Sub RadMaskedEditBox1_ValueChanging(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles RadMaskedEditBox1.ValueChanging

   

  MessageBox.Show("Value=" & RadMaskedEditBox1.Value)

   

  End Sub

  
  It does not show the proper value.
  
  Also, I'd like to know if there is a way to disable the increase/decrease value using the up/down arrows.
   
  Thanks for your help.

  Hi Mauricio,

  Thank you for writing.
  
  At this moment the value is not changed yet. So it is normal to get the old value in this event.
  You can get the actual value on ValueChanged event. Please refer to code snippet which demonstrates you can cancel the RadMaskedEditBox value based on a certain condition.

  dim oldValue as Object = ""

  Private Sub RadMaskedEditBox1_ValueChanging( sender As System.Object,  e As System.ComponentModel.CancelEventArgs) Handles RadMaskedEditBox1.ValueChanging

          me.oldValue = RadMaskedEditBox1.Value

  End Sub

   'prevent user to enter 7 as single value

  Private Sub RadMaskedEditBox1_ValueChanged( sender As System.Object,  e As System.EventArgs) Handles RadMaskedEditBox1.ValueChanged

    if me.RadMaskedEditBox1.Value = 7 then

              me.RadMaskedEditBox1.Value = oldValue

    End If

  
  I hope this helps. Kind regards,
  Peter
