Telerik Reporting Constants

The report expression context registers the following enum types. Use an enum member in an expression as =EnumType.Member.

Enum	Members	Purpose
AccessibleRoles	Ignored	Excludes an item and its descendants from the accessibility tree
AnchoringStyles	None, Top, Bottom, Left, Right	Anchors an item to its container edges
BackgroundRepeat	NoRepeat, RepeatX, RepeatY, Repeat	Sets how a background image repeats
BorderType	None, Solid, Dotted, Dashed, Double, Groove, Ridge, Inset, Outset	Sets a border line type
DockingStyle	None, Top, Bottom, Left, Right, Fill	Docks an item to its container edges
HorizontalAlign	Left, Center, Right, Justify	Sets horizontal text alignment
ImageSizeMode	AutoSize, Center, Normal, Stretch, ScaleProportional	Sets how an image fits in its item
ImageRotation	None, Auto, Rotate90, Rotate180, Rotate270	Sets image rotation
LineStyle	Solid, Dashed, Dotted	Sets the appearance of a line item
PageBreak	None, Before, After, BeforeAndAfter	Sets page breaks around a report section
PageNumberingStyle	Restart (obsolete), ResetNumbering, ResetNumberingAndCount, Continue	Controls page numbering in a report book
VerticalAlign	Top, Middle, Bottom	Sets vertical text or object alignment

The PageNumberingStyle.Restart member is obsolete. Use PageNumberingStyle.ResetNumbering instead.

Literal text

In an expression, literal text is text that is enclosed in single or double quotation marks.

Example:

="Product name: " + Fields.ProductName

or

='Product name: ' + Fields.ProductName

Because quotation marks are special characters inside the literal text, you need to double the quotation mark to escape it. Other option is to use the other quotation marks as literal delimiters (then our quotation mark will not be a special symbol). The following table shows some examples of quotation mark combinations in an expression and their result:

Expression	Result
'It''s my birthday'	It's my birthday
"It""s my birthday"	It"s my birthday
'It"s my birthday'	It"s my birthday
"It's my birthday"	It's my birthday

Some report item properties allow the usage of Embedded Expressions , which provide easy concatenation of string literals with expression terms.

Numeric constants

They are resolved to:

• Integer if decimal point is not used - for example 1, 256, 65000
• Decimal if decimal point is used - for example 1.0, 25.6

Example:

= Fields.LineTotal < 100

Date-time constants

Date values should be enclosed within pound signs #.

Example:

=Fields.Birthdate < #1/31/82#
