so i want to disable the button while user selecting item from dropdownlist until the text changes.
If doing all the stuff client side then: Attach a javascript function to Dropdownlist items or to Dropdown change event. In that JS function, just disable the button. Once you are ready with all the stuff, enable it back (like while calling different function) If doing all the stuff server side then: In selectedindex change event, disable the button. After you have worked on other functions, at the end enable the button.
