Hi yadagiri,

Sorry to respond you a little late. The problem that I can see in your page is that you're not grabbing the Text Editor properly. Do like this inside your script block:

Hi yadagiri,

sorry to ask you but It's really a bit annoying navigating through all these code with so many commented lines. Suggest you to share your project in whole or slice the relevant part only.

Hi yadagiri,

Use the pattern below:

{
if (e.KeyCode == Keys.Enter)
{
btnSendMessage.PerformClick();
}
}
--------------------------------------------
