If Field

IfField is a Field element that compares two values and inserts the text appropriate to the result of the comparison.

Field Syntax

This is how the syntax of an If field looks like:

Syntax
{ IF Expression1 Operator Expression2 TrueText FalseText }

Operators

In the table bellow are listed all the comparison operators.

Operator	Description
=	Equal to
<>	Not equal to
>	Greater than
<	Less than
>=	Greater than or equal to
<=	Less than or equal to

Expression1, Expression2

Values to compare.

TrueText, FalseText

Text that results when the comparison is true (TrueText) or false (FalseText). If FalseText isn't specified and the comparison is false, the IF field has no result. Each string containing multiple words must be enclosed in quotation marks.

Inserting

Inserting an If field is easily achieved through the RadFlowDocumentEditor's InsertField() method. It accepts code as first argument and result as second argument.

Example 1: Insert If field

editor.InsertText("Wallet: "); 
editor.InsertInline(new Run(document)); 
Run wallet = editor.InsertText("99"); 
editor.InsertBookmark("Money", wallet, wallet); 
editor.InsertBreak(BreakType.LineBreak); 
 
editor.InsertField("IF Money >= 100 \"Buy\" \"The minimum required amount is 100\"", "«T-shirt»"); 

The result of the above snippet is illustrated in Figure 1.
