Windows Presentation Foundation (WPF) – Hello World :)

Hello, I’m going to write a series of articles about WPF.

This only pretend to be an introduction. I’m learning WPF as you, so feedback is welcome.

First of all, if you want to start with WPF, you must install .NET Framework 3.0 RTM and the WCF & WPF Extensions for .NET Framework 3.0 (At this moment, the last release is November 2006 CTP).

Then, you have to create a new Windows Application (WPF)

 

Now we have a file Window1.xaml

Replace the code with this:

<Window x:Class=”EjemplosBlog.Window1″
    xmlns=”http://schemas.microsoft.com
           /winfx/2006/xaml/presentation”
    xmlns:x=”http://schemas.microsoft.com
           /winfx/2006/xaml”
    Title=”BlogSamples” 
    Height=”300″ 
    Width=”300″>
    <Grid>
      <Button Name=”btnHelloWorld” 
              Click=”btnHelloWorld_Click”
              Height=”54″ 
              Margin=”5,5,117,0″ 
              VerticalAlignment=”Top”>
       Hello World
      </Button>
    </Grid>
</Window>

A quickly review:

• btnHelloWorld is the Id/Name of the button
• btnHelloWorld_Click is the name event Click

Also, add this code to the code behind (Window1.xaml.cs)

 void btnHelloWorld_Click(object sender, RoutedEventArgs e)
 {
     btnHelloWorld.Content = “From Ezequiel 
                              Jadib Blog”;
 }

And we are ready to launch our application

I hope this is useful. Later I will post, about how we can do it the same with Triggers.
