Organize slides into sections

Overview

Use sections to organize a presentation into parts such as an introduction, results and appendix. Create or read section names, associate slides with sections, and move a section together with its slides. Sections help keep larger decks organized as content changes.

Usage example (C# / .NET)

Install Aspose.Slides for .NET before running this standalone example.

This C# example creates four named slides and two sections. Each section starts at a specific slide and includes the following slides up to the next section. The saved PPTX keeps Introduction on slides 1–2 and Results on slides 3–4.

using Aspose.Slides;
using Aspose.Slides.Export;

using var presentation = new Presentation();
presentation.Slides[0].Name = "Opening";
for (var i = 1; i < 4; i++)
{
    var slide = presentation.Slides.AddEmptySlide(presentation.Slides[0].LayoutSlide);
    slide.Name = "Page " + (i + 1);
}
presentation.Sections.AddSection("Introduction", presentation.Slides[0]);
presentation.Sections.AddSection("Results", presentation.Slides[2]);
presentation.Save("slide-sections.pptx", SaveFormat.Pptx);

FAQ

Can a section move with its slides?

Yes. Use the section-reordering workflow when you want to move the group rather than rearrange each slide separately.

What happens to a section when its slides are removed?

Removing only a section definition retains its slides; removing a section together with its slides deletes both. After editing slides, query the section again rather than assuming its old range still applies.

How do I identify the first slide in a section?

Read the section’s starting slide. An empty section has no starting slide, so check for that case before reading slide properties.
