XAML File In WPF

XAML stands for eXtensible Application Markup Language (pronounced as zammel). There are some points about XAML which are required to write here so that reader will get some idea about it.

XAML is the file with .xaml extension.
This file contains mark ups. These mark ups is used to define UI elements.

If have already worked with HTML then you have the fair idea about what I mean by mark ups here. But still to make it more clear I am giving a sample XAML.

<window
	xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”
	xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”><Button x:Name=”blueButton”
        Width=”100”
        Height=”40”
        Background=”Blue”
        Content=”Click Me” /></window>

Xmlns:x resolves XAML language definition. Consider the following example

<StackPanel x:Name=”stack”></StackPanel>

Here StackPanel is resolved by default namespace and “Name” attribute is resolved by xmlns:x namespace.

It is important to note that “x” is instance name and you can give any name based on your needs.

X:Class Attribute

This attribute specifies the class name which is associated with XAML file i.e. code behind of XAML file.
