I already write in the SelectedIndex Changed() event. But this method does not work while running. Can anybody help me in my problem? Thanks a lot :-)

hello @Soe i think AutoPostBack property of your Dropdown is set to False. So in such a condition when you select any value from dropdown then a postback to the server will not send So Set AutoPostBack property of dropdown as True; AutoPostBack=True;
