Jess,

>I have an mmUltraNumericEditor control in a form where bindingsourcemember property is set to a tinyinteger data type column of a database table. Upon running the system, it gives no compilation error but when activating the form, it gives me this annoying error: Input string was not in a correct format. The error message is pointing me to OnBindData event of the mmUltraNumericEditor control line: mmBindingStrategySimple.BindData(this, bindingSource, e);.

Can you post the error and the entire stack trace?

Best Regards,
