Prevent user to go further when custom validation on edittable widget fires

By Stijn Poppe on 19 Jun 2015
When you use the edittable widget and expand the validation in the onrowsave action and this validation fires, the user can ignore this and change or insert other data.  This should be blocked and work the same way as the default mandatory validation so the input keeps on the current record.

if you are putting custome validation , set the controls valid property to false(in case of  validation fails) and before you save if the check the edit widget's valid property if it is true go ahead and save your stuffs else refresh the widget and it will start showing the validations.
