Can anyone please help me to solve is issue.
Am using repeater control to load the data from database. Its working properly, though am going this for visually impaired persons I am using SpeechSynthesizer to serve an audio output to the users.
Without using repeater the audio is working perfectly , but I need to load 100’s of data to the page, so I bound to repeater. Using repeater the SpeechSynthesizer is not functioning. Please check my code and do the needful.
