Sorry, but are you sure this is on click event? because if you send email through on click event it should'nt run on page load. unless this is onPrerender event. I guess so...

I guess so... yes i am sure that this is on click event. it is working correctly. only problem is that after send mail when i refresh page it will again send the mail.

What exactly do you mean by "refresh"? If you mean you are hitting F5, that reloads the page exactly the same way you got to it including posted form values. That means clicking a button which does a postback and then hitting F5 causes the same exact postback as happened from the button. You could always add a hidden field on the page and in your button click check for a certain value and if that value is there don't send the message.

or use...

private void BtnSend_Click(... etc)
{
if (!IsPostBack)
{
//Your mail send code
}//end if (!IsPostBack)
}//End BtnSend_Click

:-D ... but anyway your problem is strange! i haven't seen any 'sending-mail on postback' problem! :confused: ok I hope it helps! good luck! :laugh:

That wouldn't work. A button click event is always a postback. So wrapping the code for sending mail in !IsPostBack defeats the purpose.
