anyone know how I can do if I want that when my CheckBoxList has chosen option but justification has nothing written and if I click the button to save, send me an error that justification is required and I change the border color field missing.
Find a demo project attached. I believe it's accomplishing the effect you're asking for.
Here are some screenshots as well.
I want that appeared after giving click the save button.
I adjusted the demo package to work as you requested. I'm not sure that's the way I would do the validation, but this should do as you ask.
Demo package attached. Note the functionality comes from the code in the form's Body onload and Script sections, as well as the IncludeHTML component on the form designer.
