get database values based on text entered

[shah rah]

I have a text field grpid and based on the grpid I enter I need to populate database values for 3 other text fields in the page. Should I call a action class onchange of textfield ? Is this the right approach.

Your approach is correct.It a traditional approach and its widely used, but the disadvantage of it is it would re-load the entire page again. The other way of doing it using Ajax.

Hope this helps.

Thanks and Regards,
