How to avoid special character in string box

[AnkitG]

Hi,

is there a way that a special character can be avoided in a string box, like permitting only a-z and 0-9 to enter in a string box

Hi Bijay,

Thanks for the example, this works but this will only tell me if there are specials characters present, Is there a way in which user cannot enter any special character even on rpessing the key for those special character.

Thanks,

Ankit

Hi Ankit,

did you read Darin's comment in the 2nd message of this thread? The answer is already given!

[AnkitG]

Yes,I read that but I am not able to implement that and there is no proper examples for that.

Hi Ankit,

there are examples showing usage of event structure!

Hello All,

Darin.K's method is simple. 

AnkitG : You need to modify the code.

Good Learning for me.
