TMS FNC DataGrid

TMS FNC DataGrid is the UI Pack component for tabular data. It is designed for VCL, FMX, and WEB projects and exposes the same primary component class, TTMSFNCDataGrid, across framework-specific units.

Supported Frameworks

Framework	Unit family	Notes
FireMonkey	`FMX.TMSFNCDataGrid*`	Desktop, mobile, and Linux FMX applications.
VCL	`VCL.TMSFNCDataGrid*`	Windows desktop applications.
TMS WEB Core	`WEBLib.TMSFNCDataGrid*`	Browser applications using the WEB Core runtime.

Quick Start

Create the grid, assign a parent, set the row and column count, then write values through the indexed cell API.

procedure TForm1.FormCreate(Sender: TObject);
begin
  Grid := TTMSFNCDataGrid.Create(Self);
  Grid.Parent := Self;
  Grid.Align := TAlignLayout.Client;

  Grid.ColumnCount := 3;
  Grid.RowCount := 5;

  Grid.Cells[0, 0] := 'ID';
  Grid.Cells[1, 0] := 'Name';
  Grid.Cells[2, 0] := 'Country';

  Grid.Cells[0, 1] := 1;
  Grid.Cells[1, 1] := 'John Doe';
  Grid.Cells[2, 1] := 'USA';
end;

API Map

The DataGrid API is split across a registered component, a protected base class, and owned helper objects. Application code usually works with TTMSFNCDataGrid; the related classes below explain where layout, data, rendering, options, adapters, and export behavior live.

Role	API	Ownership and use
Registered component	`TTMSFNCDataGrid`	Drop this on a form or create it in code. It publishes the main API inherited from `TTMSFNCCustomDataGrid`.
Base component	`TTMSFNCCustomDataGrid`	Declares most public and published grid members exposed by the registered component.
Geometry and layout	`TTMSFNCDataGridCore`	Owns row and column counts, fixed/frozen regions, visibility, coordinates, and scrolling.
Cell data and operations	`TTMSFNCDataGridData`	Stores cell values and coordinates sorting, filtering, grouping, calculations, and conversion.
Rendering layer	`TTMSFNCDataGridRenderer`	Draws cells, cell controls, appearance states, selection visuals, and interaction feedback.
Options	`TTMSFNCDataGridOptions`	Groups behavior switches for selection, interaction, sorting, editing, and display options.
Appearance	`TTMSFNCDataGridCellAppearance`	Holds reusable cell layouts for normal, selected, focused, fixed, summary, and grouped states.
Columns	`TTMSFNCDataGridColumns`, `TTMSFNCDataGridColumn`	Define column-level behavior, text, size, visibility, appearance overrides, and editor choices.
Database binding	`TTMSFNCDataGridDatabaseAdapter`	Connects the grid to dataset-backed data sources and maps dataset fields to grid columns.
XLS/XLSX IO	`TTMSFNCDataGridExcelIO`	Imports and exports spreadsheet data.
PDF export	`TTMSFNCDataGridPDFIO`	Exports grid output through the PDF pipeline.
Printing	`TTMSFNCDataGridPrintIO`	Sends paginated grid output to printer targets.
Column editor dialog	`TTMSFNCDataGridColumnsEditor`	Provides the column visibility and ordering editor.
