When i pulse the key [ SUPR ] on a IntegerTextBox, takes place following runtime (The same it happens in demo of syncfussion):
An unhandled exception of type ''System.ArgumentException'' occurred in system.windows.forms.dll
Additional information: ''-1'' is not a valid value for ''value''.
P.D. the version of syncfussion that I am using is the 184.108.40.206
