XAML PART II Contd..

Do you know?

1.

XAML doesn’t allow us to split the content property. It should be continuous.

For example the following is illegal and will not compile.

<Button>
<Button.Content>Hello</Button.content> <Button.content>World<button.content>
</Button>

2.

XAML is case sensitive. All the Object elements, Property Elements and attribute names are case sensitive.

Values of the attributes are not always case sensitve. For example

<button content="HelloWorld" background="green"/>

It depends upon the type-converter behaviour associated with the property that takes the value. In the above example Background=”Green” or “green” is OK

3.

XAML ignores all nonsignificant whitespaces. Spaces will be considered if it’s in content property.

<button content=" HelloWorld" margin="26,59,0,0" background=" aqua " width="90" verticalalignment="Top" horizontalalignment="Left" height="21"/>

If you notice the above example the space surrounding “aqua” will be trimmed whereas space in front of “ Helloworld” will be considered.

4.

XAML files must have only one root element. It should be a well formed XML file and a valid XAML file

How to write inline coding in XAML:

We can write the code either in code behind page or inline. Code behind is recommended as definitely it’s advantageous.
To write an inline code in XAML we have to use x:Code directive along with . Following is the sample for inline coding.

<button content="Hello" click="SayHello">
</button>

<x:code>
<![CDATA[
void SayHello (object sender, RoutedEventArgs e)
{
MessageBox.Show("Hello");
SayMorning();
}
void SayMorning (){
MessageBox.Show("Good Morning");
}
]]>


</x:code>
