4 Feb 202514 minutes to read

Sections helps to manage the slides of a PowerPoint presentation. If a presentation has many slides, you can organize the slides using sections to make the navigation easier.

Creating a section

Adding a new slide to a section

The following code example demonstrates how to add a blank slide to a section.

//Creates a PowerPoint presentation
IPresentation pptxDoc = Presentation.Create();
//Adds a section to the PowerPoint presentation
ISection section = pptxDoc.Sections.Add();
//Sets a name to the created section
section.Name = "SectionDemo";
//Adds a slide to the created section
ISlide slide = section.AddSlide(SlideLayoutType.Blank);
//Adds a text box to the slide
slide.AddTextBox(10, 10, 100, 100).TextBody.AddParagraph("Slide in SectionDemo");
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("Section.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Creates a PowerPoint presentation
IPresentation pptxDoc = Presentation.Create();
//Adds a section to the PowerPoint presentation
ISection section = pptxDoc.Sections.Add();
//Sets a name to the created section
section.Name = "SectionDemo";
//Adds a slide to the created section
ISlide slide = section.AddSlide(SlideLayoutType.Blank);
//Adds a text box to the slide
slide.AddTextBox(10, 10, 100, 100).TextBody.AddParagraph("Slide in SectionDemo");
//Saves the PowerPoint presentation
pptxDoc.Save("Section.pptx");
'Creates a PowerPoint presentation
Dim pptxDoc As IPresentation = Presentation.Create()
'Adds a section to the PowerPoint presentation
Dim section As ISection = pptxDoc.Sections.Add()
'Sets a name to the created section
section.Name = "SectionDemo"
'Adds a slide to the created section
Dim slide As ISlide = section.AddSlide(SlideLayoutType.Blank)
'Adds a text box to the slide
slide.AddTextBox(10, 10, 100, 100).TextBody.AddParagraph("Slide in SectionDemo")
'Saves the PowerPoint presentation
pptxDoc.Save("Section.PPTX")

Inserting a section

The following code example demonstrates how to insert a section in a template PowerPoint presentation that contains sections

//Load a PowerPoint presentation.
IPresentation pptxDoc = Presentation.Open("PPTXWithSections.PPTX");
//Create a new section to Insert.
ISection section = pptxDoc.Sections.Add();
//Name the created section.
section.Name = "InsertedSection";
//Insert the section at second position.
pptxDoc.Sections.Insert(1, section);
//Remove the unwanted created section.
pptxDoc.Sections.RemoveAt(pptxDoc.Sections.Count - 1);
//Save the PowerPoint Presentation as stream.
FileStream outputStream = new FileStream("Section.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Load a PowerPoint presentation.
IPresentation pptxDoc = Presentation.Open("PPTXWithSections.PPTX");
//Create a new section to Insert.
ISection section = pptxDoc.Sections.Add();
//Name the created section.
section.Name = "InsertedSection";
//Insert the section at second position.
pptxDoc.Sections.Insert(1, section);
//Remove the unwanted created section.
pptxDoc.Sections.RemoveAt(pptxDoc.Sections.Count - 1);
//Save the PowerPoint presentation
pptxDoc.Save("Sections.PPTX");
'Load a PowerPoint presentation.
Dim pptxDoc As IPresentation = Presentation.Open("PPTXWithSections.PPTX")
'Create a new section to Insert.
Dim section As ISection = pptxDoc.Sections.Add()
'Name the created section.
section.Name = "InsertedSection"
'Insert the section at second position.
pptxDoc.Sections.Insert(1, section)
'Remove the unwanted created section.
pptxDoc.Sections.RemoveAt(pptxDoc.Sections.Count - 1)
'Save the PowerPoint presentation
pptxDoc.Save("Sections.PPTX")

//Moves the second section to third position within the PowerPoint presentation.
pptxDoc.Sections[2].Move(3);
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("Section.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Loads a PowerPoint presentation
IPresentation pptxDoc = Presentation.Open("PPTXWithSections.PPTX");
//Moves the second section to third position within the PowerPoint presentation.
pptxDoc.Sections[2].Move(3);
//Saves the PowerPoint presentation
pptxDoc.Save("Sections.PPTX");
'Loads a PowerPoint presentation
Dim pptxDoc As IPresentation = Presentation.Open("PPTXWithSections.PPTX")
