<Browsable(True)>
Public Overridable Property AutoConvert As Boolean

If the AutoConvert property is set to true, all convertible characters are automatically converted accordingly to the input mask. For example, if the input mask is set to "A", then pressing a lower case character automatically converts the character into upper case.

If SBCS is entered in a DBCS mask input, the entered character is automatically converted to DBCS. Also a DBCS space is automatically converted to a SBCS space when the control allows only SBCS.
