This example makes u enable to understand how to email server controls information like Gridview as it is.
Now I am considering that we have a web form which contains a GridView (containing Data) and a button
which will be used to send email.
At first include these namespaces to your code behind.
using System.Net.Mail;
using System.Text;
using System.IO;
Now in Button Click event write this code :
send_mail() Definition :
GridViewToHtml() definition :
Now browse and send mail and output will be like this one -:
Sometime one can encountered by this error -:
RegisterForEventValidation can only be called during Render();
This means that either you have forgot to override VerifyRenderingInServerForm in code behind or EventValidation is true.
So the solution is set EventValidation to false and must override VerifyRenderingInServerForm method.

string subject = "GridView Details";
string Body = "Dear Sir/Madam ,<br> Plz Check the gridview details <br><br>";
Body += GetGridviewData(Grid1); //Elaborate this function detail later

bool send = send_mail("TestUser@gmail.com", smtpFrom, subject, Body, smtpServer);//Elaborate this function detail later
if (send == true)
{

send_mail() Definition :
public bool send_mail(string to, string from, string subject, string body, string smtpServer)
{
System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage(from, to);
msg.Subject = subject;
AlternateView view;
SmtpClient client;
StringBuilder msgText = new StringBuilder();
msgText.Append(" <html><body><br></body></html>" + body);
view = AlternateView.CreateAlternateViewFromString(msgText.ToString(), null, "text/html");

GridViewToHtml() definition :
