Next Generation Data Grid for Delphi: Paging (BETA)

[Sascha]

TMS FNC UI Pack 6.9 BETA

Intro


Working with large datasets can be challenging. When your grid contains thousands or even millions of rows, displaying them all at once isn't just impracticalit can bring your application to a crawl. That's where the built-in paging functionality in

comes to the rescue, providing a powerful yet simple way to split data into manageable chunks while maintaining excellent performance.

Why Paging Matters


When building data-driven applications, you'll often encounter scenarios where displaying all data at once simply isn't feasible:

Improved Performance: Only render visible rows, dramatically reducing memory usage and rendering time

Better User Experience: Users can navigate through data intuitively without overwhelming scrollbars

Reduced Load Times: Fetch and display data in chunks rather than loading everything upfront

Professional Appearance: Give your application a polished, enterprise-ready look with built-in navigation controls

Quick Start: Enabling Paging


Getting started with paging is remarkably simple. Here's the minimal code needed to enable paging in your grid:


procedure TForm1.SetupBasicPaging;
begin
// Enable paging
Grid.Paging := True;

// Make footer visible to show paging controls
Grid.Footer.Visible := True;
Grid.Footer.Paging.Visible := True;
end;

That's it! With just three lines of code, your grid now automatically splits data into pages and displays navigation controls in the footer.

The Paging Interface


When paging is enabled, TTMSFNCDataGrid provides a comprehensive set of navigation controls in the footer:

Navigation Buttons

• First Page: Jump to the beginning
• Previous Page: Move backward one page
• Next Page: Advance forward one page
• Last Page: Jump to the end

Page Selector A dropdown combobox displaying all available pages, allowing users to jump directly to any page.

Page Information A text display showing current position (e.g., "Page 3 of 15").

Customizing the Paging Experience


The default paging controls look great out of the box, but you can customize virtually every aspect to match your application's design:


procedure TForm1.CustomizePagingControls;
begin
// Configure paging control appearance
Grid.Footer.Paging.Size := 35; // Height of paging area

// Control which elements are visible
Grid.Footer.Paging.ShowPageSelector := True;
Grid.Footer.Paging.ShowPageInfo := True;
Grid.Footer.Paging.ShowNavigationButtons := True;

// Customize control widths
Grid.Footer.Paging.PageSelectorWidth := 120;
Grid.Footer.Paging.NavigationButtonWidth := 30;
Grid.Footer.Paging.PageInfoWidth := 180;
end;







Programmatic Navigation


While the visual controls are convenient for users, you'll often need to navigate pages programmatically. TTMSFNCDataGrid provides a rich API for this:


// Basic navigation
Grid.FirstPage; // Go to first page
Grid.LastPage; // Go to last page
Grid.NextPage; // Move forward one page
Grid.PreviousPage; // Move backward one page

// Direct page access
Grid.GoToPage(5); // Jump to page 6 (0-based index)
Grid.PageIndex := 3; // Alternative: set page directly

// Query current state
ShowMessage(Format('Currently on page %d of %d',
[Grid.PageIndex + 1, Grid.PageCount]));
Responding to Page Changes


To create a responsive application, you'll want to react when users navigate between pages. The grid provides several events for this:


procedure TForm1.GridPageChanged(Sender: TObject;
AOldPageIndex, ANewPageIndex: Integer);
begin
// Update status bar
StatusBar.Panels[0].Text := Format('Viewing page %d of %d',
[ANewPageIndex + 1, Grid.PageCount]);

// Log navigation for analytics
LogPageView(ANewPageIndex);

// Update related UI elements
UpdateDataSummary;
end;
