HTML Code(registration form):

<form id="form1" runat="server">
        <table align="center" style="border: thin solid #008080">
            <tr>
                <td colspan="3">
                    <h2>User Registration Form </h2>
                </td>
            </tr>
            <tr>
                <td>&nbsp;</td>
                <td>&nbsp;</td>
                <td>&nbsp;</td>
            </tr>
            <tr>
                <td>UserName :
                </td>
                <td>
                    <asp:TextBox ID="txtUserName" runat="server" Width="120px"></asp:TextBox>
                </td>
                <td>
                    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
                        ControlToValidate="txtUserName" ErrorMessage="!!" ForeColor="Red"
                        SetFocusOnError="True"></asp:RequiredFieldValidator>
                </td>
            </tr>
 
            <tr>
                <td>City :
                </td>
                <td>
                    <asp:TextBox ID="txtcity" runat="server" Width="120px"></asp:TextBox>
                </td>
                <td>
                    <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server"
                        ControlToValidate="txtcity" ErrorMessage="!!" ForeColor="Red"
                        SetFocusOnError="True"></asp:RequiredFieldValidator>
                </td>
            </tr>
            <tr>
                <td>Email :
                </td>
                <td>
                    <asp:TextBox ID="txtemail" runat="server" Width="120px"></asp:TextBox>
                </td>
                <td>
                    <asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server"
                        ControlToValidate="txtemail" ErrorMessage="!!" ForeColor="Red"
                        SetFocusOnError="True"></asp:RequiredFieldValidator>
                    <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
                        ControlToValidate="txtemail" ErrorMessage="invalid email" ForeColor="Red"
                        ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>
                </td>
            </tr>
            <tr>
                <td>Password&nbsp; :</td>
                <td>
                    <asp:TextBox ID="txtpassword" runat="server" Width="120px" TextMode="Password"></asp:TextBox>
                </td>
                <td>
                    <asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server"
                        ControlToValidate="txtpassword" ErrorMessage="!!" ForeColor="Red"
                        SetFocusOnError="True"></asp:RequiredFieldValidator>
                </td>
            </tr>
            <tr>
                <td>&nbsp;</td>
                <td>
                    <asp:Button ID="btnregistration" runat="server" Text="Register"
                        OnClick="btnregistration_Click" />
                </td>
                <td>&nbsp;</td>
            </tr>
            <tr>
                <td>&nbsp;</td>
                <td colspan="2">
                    <asp:Label ID="lblmsg" runat="server"></asp:Label>
                </td>
            </tr>
 
        </table>
    </form>

Step 2: Double click on the Register button in the registration form. Copy and paste the following code for saving registration details into SQL database.

Code behind(registration form):

  protected void btnregistration_Click(object sender, EventArgs e)
        {
            lblmsg.Text = "";
            string constr = ConfigurationManager.ConnectionStrings["foo"].ToString();
            SqlConnection con = new SqlConnection(constr);
            con.Open();
            string str = "insert intoUserLogin values('" + txtUserName.Text + "','" +txtpassword.Text + "','" + txtcity.Text + "','" + txtemail.Text + "')";
            SqlCommand cmd1 = new SqlCommand(str, con);
            cmd1.ExecuteNonQuery();
            con.Close();
            lblmsg.Text = "Registration Done!!";
            txtUserName.Text = "";
            txtemail.Text = "";
            txtcity.Text = "";
            txtUserName.Focus();
        }

Description:  Run the application and fill the registration details and click the register button. After saving the details it will show the message “Registration Done!!”.

Output: 

asp registration
