Pixel and scale scaling in Silverlight

Recently in the study of Silverlight, also in preparation for the Test six, while the online found some Silverlight tutorials are beta1, in the formal version of a lot of questions, so try to translate Jesse Liberty's blog to improve themselves, At the same time also hope that through this and everyone to study together.

Note: Star translation for proportional scaling, looking for a few dictionaries, looks like star does not mean that.

In Silverlight, virtually all measurements (such as high, wide, etc.) are pixels, except when it is clearly stated that they are not.

Pixel

When you create a new shape, or set an edge indent, or fill a control's length and width, implicitly (by default, the display relative) units are pixels. Such as:

Code

<Button　Content="Button" Width="100" />
<CheckBox　Content="CheckBox" Height="20" Width="75"/>
<StackPanel Orientation="Horizontal" >
　　<RadioButton Height="29" Width="106" Content="RadioButton1" />
　　<RadioButton Height="29" Width="136" Content="RadioButton2" />
</StackPanel>
<ListBox Width="100" Height="100">
</ListBox>
<Slider Width="250" Height="25"/>
<swc:Calendar Height="150" Width="200" />

From the length of the button to the height of the Calendar control, all units above are pixels.

Proportional scaling

There are two ways to set the row height or column width of the grid, one with absolute value, pixel, and the other by proportional distribution. When you draw two rows through the mouse in the blank part of the blend, the default is not to define the size of the two rows by pixel, which is interrelated, one change, and the other changes. In the panel there will be an open lock to identify it. Also, in a XAML file, add "*" to the value.
