    SpeechSynthesizer with Repeater control in Asp.Net C#

    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.

    Hi,
    Can you please tell that did you found rbt1 properly using FindControl?
    If yes then rbt1.Text contains proper text you want?
    I suggest you to do following:
    Instead of this:
    RadioButtonList rbt1 = (RadioButtonList)(rptCustomers.FindControl("rdOrtAna_ADesc"));
    Use this:
    RadioButtonList rbt1 = (RadioButtonList)(e.Item.FindControl("rdOrtAna_ADesc"));

    Hi,
    Thanks a lot for your valuable response.
    It is also not working for me. The rbt1 is showing null, but already we have loaded the data from db na?

    what error you got ? please elaborate so that we can help you better in order to resolve a issue.
    Meanwhile, have you tried using gridview control ? just try with it, I think it will work with gridview

    Hi,

    Nice to here to resolve the issue by your own, After I read your post I comment only one thing, OnRowCommand event for each index you make separate code, that is 100% wrong, because in post itself you mentioned that you have 100's of records, for 100 records are you maintain separate, separate code blocks? Samething if you observe in your resolution code block they wrote only one solution for all the indexes. So, keep remember this point for future development.
