Hi Kumar,

Did you mean you have used it in your APEX controller?

Or, in VF page within {!.....}?

It should work in Lightning Controller as well.

Can you please post the error you are getting?

Hello Kumar,

If you are using it in component controller or component helper, you can use Javascript function to get the substring.

var str = "Salesforce";
var res = str.substring(0, 1);

-Thanks,
TK
