Hi Greg,
Thanks for bringing this to our attention. It is an inconsistency in our MaskedEditBox when compared to the .Net TextBox. However, you could work around this by setting a desired PopupMenu to the control as shown in the
sample application attached here. Please let me know if this works for you. We appreciate your feedback, and thanks for choosing Syncfusion products.
