[Solved] Sending GridView's only specific Columns in email.

First step: convert gridview to html table and remove the columns you don't want
private string getHTML(GridView gv)
{

this.OrderGridView.AllowPaging = false;
this.OrderGridView.AllowSorting = false;
this.OrderGridView.EditIndex = -1;

// Let's bind data to GridView
this.RefreshGrid();
OrderGridView.Columns.RemoveAt(1);
OrderGridView.Columns.RemoveAt(0);
OrderGridView.DataBind();
// Let's output HTML of GridView
StringBuilder sb = new StringBuilder();
StringWriter textwriter = new StringWriter(sb);
HtmlTextWriter htmlwriter = new HtmlTextWriter(textwriter);
OrderGridView.RenderControl(htmlwriter);
htmlwriter.Flush();
textwriter.Flush();
htmlwriter.Dispose();
textwriter.Dispose();
return sb.ToString();
}

Then send it via email:

protected void Button1_Click(object sender, ImageClickEventArgs e)
       {
          
           try
           {
string emailGR = getHTML(OrderGridView);

               System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
               System.Net.Mail.SmtpClient smptClient = new System.Net.Mail.SmtpClient("mail.*****.***");
               smptClient.Credentials = new System.Net.NetworkCredential("**@****.gr", "*****)d");

               mail.Body = "New Order From: " + "  " + username.Text + "<br/>" + "Total Amout:" + "  " + sum.Text + "<br/>" + "Notes:" + "  " + TextBox5.Text + emailGR;
               
               mail.IsBodyHtml = true;
               mail.To.Add(new System.Net.Mail.MailAddress("****@****.**"));
               mail.From = new MailAddress("customer@****.***");
               mail.Subject = "New Order From" + "   " + username.Text;
               smptClient.Send(mail);
               string Msg = "<script>alert('You have successfully sent your order!!');</script>";
               ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "alert", Msg, false);
               //Response.Write(@"<script language='javascript'>alert('You have successfully sent your order!')</script>");
           }
           catch
           {
               string Msg = "<script>alert('Mail Sending Failed..try again!');</script>";
               ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "alert", Msg, false);
               //Response.Write(@"<script language='javascript'>alert('Mail Sending Failed..try again!')</script>");
           }
           this.OrderGridView.AllowPaging = true;
           this.OrderGridView.AllowSorting = true;
           this.OrderGridView.EditIndex = -1;
           this.RefreshGrid();
           code.Focus();

       }

Hi...
See this. May its useful to u.

//Reads values from ur gridview1.
GridViewRow gvRow = (GridViewRow)(sender as Control).Parent.Parent;
//assigning gridview1 controls to strings like blow.
string username = ((Label)GridView1.Rows[gvRow.RowIndex].FindControl("lblusername")).Text;
string fathername = ((Label)GridView1.Rows[gvRow.RowIndex].FindControl("lblfathername")).Text;
string address= ((Label)GridView1.Rows[gvRow.RowIndex].FindControl("lbladdress")).Text;
string zipcode= ((Label)GridView1.Rows[gvRow.RowIndex].FindControl("lblzipcode")).Text;
string mailid= ((Label)GridView1.Rows[gvRow.RowIndex].FindControl("lblmailid")).Text;
string phoneno= ((Label)GridView1.Rows[gvRow.RowIndex].FindControl("lblphoneno")).Text;

like that reads the values from ur GridViewRow1.After that sends that values through mail.
Thank u.

THERE ARE TWO TABLES WHICH I AM SENDING TO EMAIL.
• HTML TABLE - GETTING VALUES OF MY SERVER CONTROLS IN THE HTML TABLE
• GRIDVIEW - AFTER CONVERTING IT TO HTML.
SENDING THE HTML TABLE AND GRIDVIEW(HTML FORMAT) TO EMAIL

private void emaildatatable()
    {
        string reqini = ExEMP_PERSONAL.getEmpName(Session["empCode"].ToString());

        StreamReader reader = new StreamReader(Server.MapPath("~/Email Templates/old/RequestHeader.htm"));
        string readFile = reader.ReadToEnd();
        string substring = "";
        substring = readFile;
        substring = substring.Replace("#ParentRequestNo#", parentTaskNo);
        substring = substring.Replace("#RequestInitiator#", reqini);
        substring = substring.Replace("#RequestDate#", Label39.Text);
        substring = substring.Replace("#ApprovingAuthority#", DropDownList3.SelectedItem.Text);
        substring = substring.Replace("#ApprovalHeader#", "Approval");
        substring = substring.Replace("#ApprovalDisapprovalDate#", "N/A");
        substring = substring.Replace("#RequestNotifications#", "");

        string body = "<h1 align="center">Change Management System</h1><br>";
        body += "<br><br>";
        string to = ExEMP_PERSONAL.getEmpEmail(Session["empCode"].ToString());
        MyEmail mm = new MyEmail();
        body += substring.ToString();
        body += "<br><br>";
        body += "<h3 align="center">Account Closing Request</h3>";
        body += GridViewToHtml(GridView3).ToString();
        mm.sendEmail(to, "", "", "Your Request No. " + parentTaskNo + " is Submitted for Approval -- ( " + tskctrl.getTaskImpact(parentTaskNo) + " )", body);
        
    }

private string GridViewToHtml(GridView gv)  
    {
        StringBuilder sb = new StringBuilder();
        StringWriter sw = new StringWriter(sb);
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        gv.RenderControl(hw);
        return sb.ToString();
    }
