I have two dropdown box when a user select the first dropdown box.
the second dropdown box will be populated with data without affecting other controls in the form.

Example the first dropdown box is populated a list of department, so when theuser selects a department the second combo box will be populated the list of employees belonging to that department that was selected by the user on the first dropdown box without affecting other controls in the form?
Both dropdown box get the data from the database.

Can some one show me how to do this?

Thanks very much.

There are at least two ways to do this:

1. Call a JavaScript function in the onchange event of the first dropdown. This means that you will have to create JavaScript arrays that will hold all the possible combinations.

2. Submit the form via a JavaScript function call in the onchange event. In the backend, detect what the selected item was in the first drop down and then re-populate the options collection for the second drop down accordingly.
 
It would give a normal human mental abilities to rival mine. To think it is just a tiny ad:
