hi,
I have a simple program with dropdownlist and textbox.
Write any text in the textbox and change the dropdownlist.
On dropdownlistchange i alert the results.
The program works well on my computer but when i copy the project to
the server it doesn't work. It doesn't go in the
DropDownList1_SelectedIndexChanged at all!!!
Like it doesn't exist!!! it goes to the 'Page Load' function and shows
the textbox value and show nothing on the dropdownlist alert.
please tell me what i did wrong ?????????
thanks
