TTMSFNCDataGridCore.RealToVisualRow Method

Converts a physical storage row index to the 0-based row index in the currently rendered output (sort applied, and filtered/hidden rows skipped). Returns -1 when the row is filtered or hidden.

API unit family: TMSFNCDataGridCore Declaring type: TTMSFNCDataGridCore

Syntax

function RealToVisualRow(ARow: Integer): Integer;

Remarks

This is distinct from RealToDisplayRow, which only accounts for sort/reorder. Use this when you need the visual row position (e.g. the slot the user sees on screen). Fixed top/bottom rows always render and map to their display-order index unchanged. Note: not to be confused with VisibleRowCount, which refers to viewport (scroll-window) extent.

Parameters

Name	Description
ARow	Zero-based row index used by the operation.

Returns

The resulting zero-based index or count.
