But the whole point/reason of using the Ajax technique is NOT to have the page refreshed!

When you still want to do that, you'll have to take precautions by preserving the selected box'es values, and setting the already clicked dropdown options to 'selected=selec ted'.

on dat page im having a button which when clicked opens a pop and some data is entered in dat pop up window,when pop window is closed the data dat is entered is to be reflected in one of the dropdowns in the page.

so onclose event of pop up window i refresh d parent window for d same.

but on refresh i loose the dropdown from page which i have created using ajax.

thnx

You don't need to refresh the page for that. Just use

window.opener

to access the opening window. Once you've set the dropdown, close the popup.

hi

thnx for reply.

but problem is not opening the pop window,problem is to retain the dropdown boxes after the pop window is closed and the parent gets refreshed,i loose all the dropdowns created using AJAX and their selected values.

thnx

I think you've misunderstood my reply. See this page. You can use 'window.opener' to reference the parent window. Once you have that ref. you can manipulate the dropdowns.
