I have a textbox which I will be using regularexpressionvalidator to check.
The textbox value must be alphanumeric.
or it can be alphabetics.
like..
abc - Pass
abc123 - Pass
123abc - Pass
abc123!@# - fail
123456 - fail
!@#1234 - fail
How to write a regular expression for that?
One of my seniors solved the problem by using this expression.
^[A-Za-z0-9 ]*[A-Za-z]+[A-Za-z0-9 ]*And trim the textbox value when retrieving it.
