You mean ur textbox accepts only alphabets? if user enters numbers or special symbol then redirect to exceptionpage.aspx and display the error message? right..

Try this:

C#

protected void btnsubmit_Click(object sender, EventArgs e)
{
    Match match = Regex.Match(txtname.Text, @"(?i)^[a-z]+");
    if (match.Success)
    {
    
    }
    else
    {
        Response.Redirect("Exceptions2.aspx");
    }
}
