Introduction: In this article I have explained how we can create contact us page in Asp,net.

Contact us page is a major part of websites through which users send comments, queries feedback etc. of website to admin/website owner.

Add a new webform to website. Drag and drop the Textbox, button, validation controls from Toolbox and desgin the .aspx page as shown below:

<table align="center">

    <tr><td><h1>Contact Us</h1></td><td></td></tr>

    <tr><td>Name:</td><td><asp:TextBox ID="txtname" runat="server"></asp:TextBox><asp:RequiredFieldValidator ID="rfvName" runat="server"

                                        ControlToValidate="txtname" Display="None"

                                        ErrorMessage="Enter Name" EnableTheming="True"></asp:RequiredFieldValidator></td></tr>

     <tr><td>Email:</td><td><asp:TextBox ID="txtemail" runat="server"></asp:TextBox><asp:RequiredFieldValidator ID="rfvrequireemail" runat="server"

                                        ControlToValidate="txtemail" Display="None"

                                        ErrorMessage="Enter Email" EnableTheming="True"></asp:RequiredFieldValidator>

         <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"

             ControlToValidate="txtemail" ErrorMessage="Enter Valid Email"

             ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>

         </td></tr>

      <tr><td>Subject:</td><td><asp:TextBox ID="txtsubject" runat="server"></asp:TextBox> <asp:RequiredFieldValidator ID="rfvsubject" runat="server"

                                        ControlToValidate="txtsubject" Display="None"

                                        ErrorMessage="Enter Subject" EnableTheming="True"></asp:RequiredFieldValidator></td></tr>

       <tr><td>Description:</td><td><asp:TextBox ID="txtdescription" runat="server" TextMode="MultiLine" textl></asp:TextBox> <asp:RequiredFieldValidator ID="rfvdescription" runat="server"

                                        ControlToValidate="txtdescription" Display="None"

                                        ErrorMessage="Enter Description" EnableTheming="True"></asp:RequiredFieldValidator></td></tr>

                                        <asp:ValidationSummary ID="ValidationSummary1" runat="server"  ShowMessageBox="true" ShowSummary="false"/>

        <tr><td>&nbsp;</td><td><asp:button ID="btnsend" runat="server" Text="Send"

                onclick="btnsend_Click" /></td></tr>

    </table>

After that on button click (.aspx.cs) write the given code:

using System.Net.Mail;

protected void btnsend_Click(object sender, EventArgs e)

    {

        try

        {

            MailMessage msg = new MailMessage("Sender Email Id","Recevier Email Id");

            msg.Subject = txtsubject.Text;

            msg.Body = "Name:"+txtname.Text+"<br> Email:"+txtemail.Text+"<br>" + txtsubject.Text;

            msg.IsBodyHtml = true;

            SmtpClient smtp = new SmtpClient();

            smtp.Host = "smtp.gmail.com";

                smtp.Port = 587;

                smtp.Credentials = new System.Net.NetworkCredential("Email Id", "Password");

                smtp.EnableSsl = true;

            smtp.Send(msg);

            Clear();

            Messagebox("Mail send Successfully");

        }

        catch (Exception ex)

        {

        }

    }

    private void Clear()

    {

        txtname.Text = "";

        txtsubject.Text = "";

        txtemail.Text = "";

        txtdescription.Text = "";

    }

    //Show Message

    private void Messagebox(string Message)

    {

        Label lblMessageBox = new Label();

        lblMessageBox.Text =

            "<script language='javascript'>" + Environment.NewLine +

            "window.alert('" + Message + "')</script>";

        Page.Controls.Add(lblMessageBox);

    }

In VB (.aspx.vb)

Imports System.Net.Mail

Protected Sub btnsend_Click(sender As Object, e As System.EventArgs) Handles btnsend.Click

        Try

            Dim msg As New MailMessage("Sender Email Id","Recevier Email Id ")

            msg.Subject = txtsubject.Text

            msg.Body = (("Name:" + txtname.Text & "<br> Email:") + txtemail.Text & "<br>") + txtsubject.Text

            msg.IsBodyHtml = True

            Dim smtp As New SmtpClient()

            smtp.Host = "smtp.gmail.com"

            smtp.Port = 587

            smtp.Credentials = New System.Net.NetworkCredential("Email Id", "Password")

            smtp.EnableSsl = True

            smtp.Send(msg)

            Clear()

            Messagebox("mail Send Successfully")

        Catch ex As Exception

        End Try

    End Sub

    Private Sub Clear()

        txtname.Text = ""

        txtsubject.Text = ""

        txtemail.Text = ""

        txtdescription.Text = ""

    End Sub

    'Show Message

    Private Sub Messagebox(Message As String)

        Dim lblMessageBox As New Label()

        lblMessageBox.Text = "<script language='javascript'>" + Environment.NewLine & "window.alert('" & Message & "')</script>"

        Page.Controls.Add(lblMessageBox)

    End Sub

Run the project and check the result.
