SpeechSynthesizer with Repeater control in Asp.Net C#

May 18 2016 2:43 AM

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.

SOURCE CODE:

async="true" %>

<%@ Register assembly="AjaxControls" namespace="AjaxControls" tagprefix="cc1" %>
