How to pass Form Template Edit Form textbox value to code behind

[ILJIMAE]

I have a RADGrid named 'RadGrid1' in my aspx page.

RadGrid1 has a form template edit form and this edit form contains:

• A text box with an ID 'txtEmail' for editing the email address of the selected record
• A button with an ID 'ButtonA'

What I am trying to do is:

When user click the 'ButtonA' button,
I want to send the email address information shown in the 'txtEmail' text box of the selected record to the code behind file's 'ButtonA' onClick event procedure.

I need to know the correct syntax/code for doing this.

Code behind file:

protected void ButtonA_Click(object sender, EventArgs e)
{
    string EmailAddress = // How can I get the email address information shown in the ‘txtEmail’
                   //  text box in the Form Template Edit Form
}

Thank you. :D

Thank you very much for you perfect, crystal clear solution Mr Goyani.
Also, thank you for the bonus button click event code for the button placed outside the form template edit form. :D
