Table Control Dropdown List Problem

Former Member — Fri, 04 Jan 2008 01:41:06 GMT

Hi,

I have this problem with my table control.

I now have an input field (with input help) called: Reference Table, as well as a table control.

What i need is to select the table names (select from the Reference table input help) and the field names will be populated inside the table control (according to the field names inside the respective tables) as a dropdown list.

Refer to this diagram if unclear: http://img166.imageshack.us/img166/1066/tablecontrolwt4.png

Please give me sample codes as i really need help.

Will reward marks if useful.

thanks a lot.

Below is my codes:
