Question

I am facing a problem while text field creation, i.e I can create a field by using all blank spaces. I have used "allowblank:false" but still its allowing only whitespaces. My textfield id is Textfield_value.

Answer 1

Finally I got an answer to this question.

this. Field name.addListener({

            blur : function(){
                this.setValue(this.getValue().trim());
            }
        });

This trims the white spaces in the textfield

Thanks for the answers
