Login and Registration process in WPF application with C# .Net

In this concept I will discuss a simple application for login and registration using WPF in visual studio 2008 and onwards version. In this application I am creating three window forms one is for Registration, Login and Welcome

Now I am going to discuss in brief about this application.

Step1: Open Visual Studio 2010 -> File -> New -> Project. -> Windows-WPF Application

Then we take MainWindow.xaml for the Registration Page, if you want to change then rename it and also change the StartupUri property of application into App.xaml like as follows:

<Application x:Class="RegistrationLoginConcept.App"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

StartupUri="LoginPage.xaml">

<Application.Resources>

</Application.Resources>

</Application>

Step 2: Now design your Registration page copy which is given below in Picture following inline code.

MainWindow.xaml:

<Window x:Class="RegistrationLoginConcept.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="Registration Page" Height="540" Width="525" ResizeMode="NoResize">

<Button.Template>

</TextBlock>

</ControlTemplate>

</Button.Template>

<Button.Style>

<Style.Triggers>

</Trigger>

</Style.Triggers>

</Style>

</Button.Style>

</Button>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</StackPanel>

</ComboBox>

</Grid>

</Window>

MainWindow.xaml.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Windows;

public partial class MainWindow : Window

{

{

}

SqlConnection con;

string gen,details,course;

private void btnSubmit_Click(object sender, RoutedEventArgs e)

{

lblmessage.Content = "";

if (txtemailid.Text.Length == 0)

{

lblmessage.Visibility = System.Windows.Visibility.Visible;

lblmessage.Foreground = Brushes.Red;

lblmessage.Content = "Enter an email.";

txtemailid.Focus();

}

else if (!Regex.IsMatch(txtemailid.Text, @"^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$"))

{

lblmessage.Visibility = System.Windows.Visibility.Visible;

lblmessage.Foreground = Brushes.Red;

lblmessage.Content = "Enter a valid email.";

txtemailid.Select(0, txtemailid.Text.Length);

txtemailid.Focus();

}

else

{

if (txtpassword.Password.Length == 0)

{

lblmessage.Visibility = System.Windows.Visibility.Visible;

lblmessage.Foreground = Brushes.Red;

lblmessage.Content = "Enter password.";

txtpassword.Focus();

}

else if (txtcpassword.Password.Length == 0)

{

lblmessage.Visibility = System.Windows.Visibility.Visible;

lblmessage.Foreground = Brushes.Red;

lblmessage.Content = "Enter Confirm password.";

txtcpassword.Focus();

}

else if (txtpassword.Password != txtcpassword.Password)

{

lblmessage.Visibility = System.Windows.Visibility.Visible;

lblmessage.Foreground = Brushes.Red;

lblmessage.Content = "Confirm password must be same as password.";

txtcpassword.Focus();

}

else

{

string course = ((ComboBoxItem)cblCourse.SelectedItem).Content.ToString();

// course = cblCourse.Text;

// string password = txtpassword.Password;

foreach (UIElement ui in stackCheckBox.Children)

{

if (ui is CheckBox)

{

CheckBox chk = (CheckBox)ui;

if (chk.IsChecked == true)

{

details += chk.Content + ",";

}

if (rbGender.IsChecked == true)

{

gen = rbGender.Content.ToString();

}

else

{

gen = rbGender1.Content.ToString();

}

con = new SqlConnection("Data Source=INDIA11;Initial Catalog=WpfTest;Integrated Security=True");

// SqlCommand cmd = new SqlCommand("insert into User_Registration values('" + txtUserName.Text + "','" + gen + "','" + txtemailid.Text + "','" + txtpassword.Password + "','" + details.Remove(details.Length - 1) + "','" + course + "','" + txtaddress.Text + "')", con);

SqlCommand cmd = new SqlCommand("insert into User_Registration values(@UserName,@Gender,@EmailId,@Password,@Details,@Course,@Address)", con);

cmd.Parameters.AddWithValue("@UserName", txtUserName.Text);

cmd.Parameters.AddWithValue("@Gender", gen);

cmd.Parameters.AddWithValue("@EmailId", txtemailid.Text);

cmd.Parameters.AddWithValue("@Password", txtpassword.Password);

cmd.Parameters.AddWithValue("@Details", details.Remove(details.Length - 1));

cmd.Parameters.AddWithValue("@Course", course);

cmd.Parameters.AddWithValue("@Address", txtaddress.Text);

con.Open();

cmd.ExecuteNonQuery();

con.Close();

lblmessage.Visibility = System.Windows.Visibility.Visible;

lblmessage.Foreground = Brushes.Green;

lblmessage.Content = "Registration Successfully ";

}

// Resert all control

private void btnReset_Click(object sender, RoutedEventArgs e)

{

ResetAllClear();

}

private void ResetAllClear()

{

foreach (UIElement ui in ChildGrid.Children)

{

if (ui is TextBox)

{

TextBox tt = (TextBox)ui;

tt.Text = "";

}

if (ui is PasswordBox)

{

PasswordBox pp = (PasswordBox)ui;

pp.Password = "";

}

foreach (UIElement ui in stackCheckBox.Children)

{

if (ui.GetType() == typeof(CheckBox))

{

CheckBox chk = (CheckBox)ui;

chk.IsChecked = false;

}

cblCourse.SelectedIndex = 0;

}

private void btnCancel_Click(object sender, RoutedEventArgs e)

{

Close();

}

private void Login_Click(object sender, RoutedEventArgs e)

{

LoginPage ll = new LoginPage();

ll.Show();

}

Now I am taking another form for login as follows:

LoginPage.xaml………………………….

<Window x:Class="RegistrationLoginConcept.LoginPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="LoginPage" Height="500" Width="476">

please click on

</TextBlock>

</TextBlock>

</StackPanel>

</Label>

</StackPanel>

</Window>

{

}

WelComePage wc = new WelComePage();

private void Button_Click(object sender, RoutedEventArgs e)

{

if (txEmailId.Text.Length == 0)

{

errormessage.Text = "Enter an EmailId";

txEmailId.Focus();

}

else if (!Regex.IsMatch(txEmailId.Text, @"^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$"))

{

errormessage.Text = "Enter a valid email.";

txEmailId.Select(0, txEmailId.Text.Length);

txEmailId.Focus();

}

else

{

string email = txEmailId.Text;

string password = txtPassword.Password;

SqlConnection con = new SqlConnection("Data Source=INDIA11;Initial Catalog=WpfTest;Integrated Security=True");

con.Open();

SqlCommand cmd = new SqlCommand("select * from User_Registration where EmailId='" + email + "' and Password='" + password + "'", con);

cmd.CommandType = CommandType.Text;

SqlDataAdapter da = new SqlDataAdapter();

da.SelectCommand = cmd;

DataSet ds = new DataSet();

da.Fill(ds);

if (ds.Tables[0].Rows.Count > 0)

{

wc.tbname.Text= ds.Tables[0].Rows[0]["Name"].ToString();

wc.tbgender.Text = ds.Tables[0].Rows[0]["Gender"].ToString();

wc.tbemailid.Text = ds.Tables[0].Rows[0]["EmailId"].ToString();

wc.tbdetails.Text = ds.Tables[0].Rows[0]["Details"].ToString();

wc.tbcourse.Text = ds.Tables[0].Rows[0]["Course"].ToString();

wc.tbaddress.Text = ds.Tables[0].Rows[0]["Address"].ToString();

wc.Show();

Close();

}

else

{

errormessage.Text = "Sorry! Please enter existing emailid/password.";

}

con.Close();

}

private void Hyperlink_Click(object sender, RoutedEventArgs e)

{

MainWindow mm = new MainWindow();

mm.Show();

}

Result

Now I am taking another form for WelComePage as follows:

WelComePage.xaml………………………….

<Window x:Class="RegistrationLoginConcept.WelComePage"
