QuestionHow to resolve my problem? Pin
hoang hoa tham1-Jul-08 20:11
Memberhoang hoa tham1-Jul-08 20:11 
I have to write a classic ASP page.I have a page which has a html table with some row , each row has some controls with several textboxes and 3 select controls(dropdownlist). At table's below, there is a Add button to add new row. When click on Add button, the new row will be added(with full of textboxes and select controls as same to other rows, and they have the same ID, too). What I wanna do is after selected an item from the first dropdownlist, data will be loaded from server and filled in the second dropdownlist on the same row, and after selected an item from the second one, data will be loaded form server to fill in the third one. I wonder after select an item from the first dropdownlist, I need to reload page to load data and fill the second one, and if I have some rows already has been filled data in textbox control etc will be lost. To resolve it, I've tried to use AJAX technology but It didn't work with IE though that worked with Firefox. Please help me to resolve this problem? If you can show me code better.
