Using expressions in textColor and bgColor attributes

The textColor and bgColor attributes accept the following kinds of values:

A color value literal
A hex value
An expression that selects a text color based on the evaluation of a Boolean expression

The syntax for an expression is as follows:

(CX operator string ? true_condition : false_condition)

The symbol meanings are as follows:

CX: the column that contains the value to test. For the current column, use CX; if n is the column to evaluate, use Cn; for example, C2
operator: One of these operators: EQ (equal), GT (greater than), LT (less than)
string: Value to compare against. A literal, such as (C2 EQ Johnson ? blue : green); or numeric: (C2 LT 0 ? red : black)
true_condition: Value for textColor if condition evaluates to "true"
false_condition: Value for textColor if condition evaluates to "false"

If the string in the expression can be interpreted as a number, the comparisons in the expression are interpreted as numeric. Otherwise, the comparison is a string comparison.

This code shows an expression that displays the grid element in blue if the grid element contains the string "Pam"; or black, otherwise:

<cfgridcolumn name = "FirstName" textColor = "(CX EQ Pam ? blue : black)">

This example displays the text in red if the value in column 1 is greater than four; or black, otherwise:

<cfgridcolumn name = "FirstName" textColor = "(C1 GT 4 ? blue : black)">
