For now, I've created separate issues on your behalf myself:1 ID Q158582 (DXValidation Provider - How to validate a Text Edit by the text length), 2 ID Q158586 (DXValidation Provider - How to close a Form that contains a control with an invalid value), and will post my answers there. Ive corrected my code with your suggestion and its validating now.Its not really working as expected..instance: - I would like to make sure that the input is Greater Or Equal then 2 characters.In this example I am implementing an generic validation rule that takes a regular expression as validation rule.
If the expression matches the data is treated as valid.
if there are six textforms in a winform I think it's not a good way to write if((Textbox1.text=="")&&(Textbox1.text==null)) .
