TTMSFNCDataGridConditionalFormatting.AddExpressionRule Method

Adds a grtExpression rule that matches rows for which a boolean expression evaluates to true.

API unit family: TMSFNCDataGridConditionalFormatting Declaring type: TTMSFNCDataGridConditionalFormatting

Syntax

FMX.TMSFNCDataGridConditionalFormatting.hppPascalC++

function AddExpressionRule(const AExpression: string): TTMSFNCDataGridFormatRuleItem;

TTMSFNCDataGridFormatRuleItem* __fastcall AddExpressionRule(const System::UnicodeString AExpression);

Remarks

The rule's scope is grsGrid, so a matching row is formatted in every column; chain TTMSFNCDataGridFormatRuleItem.ForColumn to format a single column instead. A bare condition without [ ] binds to TTMSFNCDataGridFormatRuleItem.Column, which is 0 unless set; see TTMSFNCDataGridFormatRuleItem.EffectiveExpression.

Parameters

Name	Description
AExpression	The boolean expression evaluated against each row, in the grid's filter expression syntax.

Returns

The newly added rule, owned by the collection.
