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


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">
<Grid  Height="600" Width="525" Background="Bisque">

<TextBlock Height="23" HorizontalAlignment="Left" Margin="10,5,0,0" Name="textBlockHeading" Text="Registration Page" VerticalAlignment="Top" Width="174"  FontSize="17" FontStretch="ExtraCondensed"/>

<!--Button as a Link button using style-->

<Button Margin="451,5,12,288" Content="Login" Cursor="Hand" Click="Login_Click">

<Button.Template>

<ControlTemplate TargetType="Button">

<TextBlock TextDecorations="Underline">

<ContentPresenter />

</TextBlock>

</ControlTemplate>

</Button.Template>

<Button.Style>

<Style TargetType="Button">

<Setter Property="Foreground" Value="Navy" />

<Style.Triggers>

<Trigger Property="IsMouseOver" Value="true">

<Setter Property="Foreground" Value="Red" />

</Trigger>

</Style.Triggers>

</Style>

</Button.Style>

</Button>

<!--end Button as a Link button using style-->
