XAML stands for eXtensible Application Markup Language. It is the language used to instantiate.NET objects. It is the language developed by Microsoft to write USER interface for next generation APPLICATIONS.

XML is designed to STORE data or to work with the stored data, whereas XAML is the extended version of XML used for.NET programming.

The advantage of using XAML is:

• XAML code is clear to read, and they are SHORT
• Separation of designer code and LOGIC
• Tools like expression blend used for GRAPHICAL design require XAML as SOURCE
• It clearly separates the ROLES of designer and developer

The advantage of using XAML is:

DISPLAYING “HELLO World.”

<page xmlns= ‘’ ‘’>
<TEXTBLOCK>
Hello, World!
</TextBlock>
</Page>

Displaying “Hello World.”

<page xmlns= ‘’ ‘’>
<TextBlock>
Hello, World!
</TextBlock>
</Page>

In XAML, graphic COMPONENTS are specified with by open or CLOSED TAGS with ATTRIBUTES.

For example,
Tag with contents
<Button&GT;
Click
</Button>
Tag without contents
< Button/>

In XAML, graphic components are specified with by open or closed tags with attributes.

For example,
Tag with contents
<Button>
Click
</Button>
Tag without contents
< Button/>

In XAML, attribute syntax sets a value for a property or names the event handler for an event, by declaring an attribute on an element.The attribute value should be enclosed within two QUOTATION marks (“).

For example,

&LT; Button Background = “Black” FOREGROUND “Red” CONTENT = “This is an operating button”/>

XAML represents a LANGUAGE FEATURE whereby a class can allot exactly ONE of its PROPERTIES as XAML property

MARKUP extensions are PLACEHOLDERS in XAML that are USED to resolve property at runtime. A markup extension ALLOWS you to extend XAML and using attribute SYNTAX you can also set any property that can be set in XAML.The purpose of the mark up extension is to process a string and return an object. Some of the standard markup extensions are xNull, x: Array, :StaticResource and DynamicResource.

The FOUR general kind of XAML elements are:

1. ROOT Elements
2. Panel Elements
3. CONTROL Elements
4. GEOMETRIC Elements

The four general kind of XAML elements are:

The X: PREFIX is used to MAP the XAML NAMESPACE in templates.

The X: prefix is used to map the XAML namespace in templates.

1. x: Key à It sets a unique key for each resource in a Resource Dictionary
2. x: Classà It specifies the CLR ( Common LANGUAGE Runtime) NAMESPACE and class NAME for the class that provides CODE
3. x: Name à It specifies a run-time object name for the instance that exist in run time code after an object element is processed
4. x: Static à It enables a reference that returns a static value which otherwise an XAML compatible property
5. x: Type à It constructs a Type reference based on the type name

To avoid MARK up EXTENSION you have to use an empty pair of CURLY braces like

Content = “{} {This is not a MARKUP extension}”/>

To avoid mark up extension you have to use an empty pair of curly braces like

Content = “{} {This is not a markup extension}”/>

Three types of CHILDREN an object ELEMENT can have:

1. Collection Items
2. A VALUE for the content property
3. The value that can be type-converted to the object element

Three types of children an object element can have:

The type converter is helpful to convert a STRING into the appropriate value type where there is no MARKUP extension usage. Type Converter DEFINES four members for CONVERTING to and from string for xaml PURPOSES.

• CanConvertTo
• CanConvertFrom
• ConvertTo
• ConvertFrom

The type converter is helpful to convert a string into the appropriate value type where there is no markup extension usage. Type Converter defines four members for converting to and from string for xaml purposes.

To instantiate a CLR CLASS or STRUCTURE by declaring an XML element, an XAML markup SYNTAX is used. This syntax is referred as Object Element Syntax.

To instantiate a CLR class or structure by declaring an XML element, an XAML markup syntax is used. This syntax is referred as Object Element Syntax.

To declare objects in XAML, there are three ways:

1. DIRECTLY, using OBJECT element syntax: This syntax is used to declare root objects or NESTED objects that set property values
2. Indirectly by using attribute syntax: This syntax uses an INLINE string value which has an instruction on how to create an object. To set the value of the property to a newly created reference, the XAML parser uses this string
3. Using a markup extension.

To declare objects in XAML, there are three ways:

In XAML document, the root ELEMENT CONSISTS only certain elements, and these elements are WINDOW, a CANVAS or panels.

Data binding PROVIDES a simple way to DISPLAY and interact with data. An EXAMPLE will show how you can do data binding in XAML. The binding in XAML is done by using {binding….} syntax.

ONE WAY of displaying data at run TIME and design time is to declare your data in XAML.
Another way of doing it is by declaring it in XAML by using various data attributes from the DESIGNER XML namespace. With a d: prefix, this namespace is typically declared.

X: KEY uniquely identifies ELEMENTS that are created and referenced in an XAML defined DICTIONARY. By adding an x: Key VALUE to an XAML object element a resource in the resource dictionary can be identified and is the most COMMON way to identify.

With the HELP of property element SYNTAX, you can ADD CHILDREN element with a NAME in the form of parent.propertyName.

With the help of property element syntax, you can add children element with a name in the form of parent.propertyName.

Custom classes are USED in two WAYS:

1. With the code that produces the Primary Windows Presentation Foundation (WPF) APPLICATION or within the code behind.
2. In a SEPARATE assembly as a class, such as an executable or DLL used as a class library.

Custom classes are used in two ways:

NAMESPACE can be DEFINED as an environment or an ABSTRACT container used to hold a logical grouping of unique identifiers or SYMBOLS.

Namespace can be defined as an environment or an abstract container used to hold a logical grouping of unique identifiers or symbols.
