Auto-Formatting Events

Auto-formatting may occur when any of the following events is detected.

Completion of an end tag or simple tag.
Completion of a start tag.
Pasting from the clipboard.
Formatting keyboard commands.

You can specify which events cause auto-formatting.

Name	Description
On completion of end tag or simple tag	Auto-formatting occurs when you finish typing an end tag or a simple tag. A simple tag has no attributes, for example `<Button />`.
On completion of start tag	Auto-formatting occurs when you finish typing a start tag.
On paste from clipboard	Auto-formatting occurs when you paste XAML from the clipboard into XAML view.

Quotation Mark Style

This setting indicates whether attribute values are enclosed in single or double quotation marks. The auto-formatter and IntelliSense auto-completion both use this setting.

Once you set this option, only attributes subsequently added either using the designer or manually in the XAML view are affected.

Name	Description
Double quotes (")	Attribute values are enclosed in double quotes. `<Button Name="button1">Hello</Button>`
Single quotes (')	Attribute values are enclosed in single quotes. `<Button Name='button1'>Hello</Button>`

Tag Wrapping

You can specify a line length for tag wrapping. When tag wrapping is enabled, any XAML subsequently added by using the designer will be wrapped appropriately.

Name	Description
Wrap tags that exceed specified length	Specifies whether lines are wrapped at the line length specified by Length.
Length	The number of characters a line may contain. If necessary, some XAML lines might exceed the specified line length.

Attribute Spacing

Use this setting to control how attributes are arranged in your XAML document

Name	Description
Preserve newlines and spaces between attributes	New lines and spaces between attributes are not affected by auto-formatting. `<Button Height="23" Name="button1"` `Width="75">Hello</Button>`
Insert a single space between attributes	Attributes occupy one line, with one space separating adjacent attributes. Tag wrapping settings are applied. `<Button Height="23" Name="button1" Width="75">Hello</Button>`
Position each attribute on a separate line	Each attribute occupies its own line. This is useful when many attributes are present. `<Button` `Height="23"` `Name="button1"` `Width="75">Hello</Button>`
Position first attribute on same line as start tag	When checked, the first attribute appears on the same line as the element's start tag. `<Button Height="23"` `Name="button1"` `Width="75">Hello</Button>`
