<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="Create Document" OnClick="OnButtonClicked" /> </div> </form> </body> </html>
- Include the following namespace in your MainPage.aspx.cs file.
using Syncfusion.Presentation;
Imports Syncfusion.Presentation

C#:
//Creates a PowerPoint instance
IPresentation pptxDoc = Presentation.Create();
//Adds a slide to the PowerPoint presentation
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add a textbox to the slide
IShape shape = slide.AddTextBox(10, 10, 500, 100);
//Add a text to the textbox.
shape.TextBody.AddParagraph("Hello World!!!");
//Save the PowerPoint Presentation
pptxDoc.Save("Sample.pptx", FormatType.Pptx, Response);
//Close the PowerPoint presentation
pptxDoc.Close();
