c# - dropdown selectedindexchanged issue within modalpopup extender -


i'm having dropdown in modalpopupextender. dropdown values updated dynamically.

the problem while clicking on button in modal popup...the dropdown values refreshed. tried take selected value of dropdown within sectedindexchanged event. if put breakpoint control not coming.
