Please tell me

Hi,

I have 2 combo box out of which first is filled with data from a field from DB and the second should be populated on the basis of the selection of the first.
Could you please help me how to achieve this

Well you either have to submit your form back to the server or use Ajax.

It is normally called a "Double Combo" or "LInked Selects" and it has been discussed many times in this forum.

Hi,

I suggest doing something similar to this:

All we need to display some option is to get the corresponding ID and set selected as true on that.

Thanks,
Sandip

No, you don't. There is no such thing as a "combo box" in HTML. Please read this for more information.
