How to change the Index of slides in powerpoint presentation?

[ishan]

I have developed an application in ASP.net and have used syncfusion to control powerpoint. Now i have generated a presentation and I want to change the order of the slides. Is there any functionality in syncfusion which allows me to do so? If yes, kindly let me know how can I change the index of slides in an existing presentation?

Hi Ishan, 

Thank you for contacting Syncfusion support. 

We can change the slide order in a PowerPoint Presentation with the below code snippet. In this code snippet, we have swapped the positions of slide 3 and 2.   

//Open an existing Presentation    

IPresentation presentation = Presentation.Open("Sample.pptx");               

//Clone the slide to which we need to change the position. Here we have cloned the slide at index position 2  

ISlide slide = presentation.Slides[2].Clone();               

//Insert the cloned slide in the required index position   

presentation.Slides.Insert(1, slide);               

//Remove the existing slide which we have inserted in another position. Now its position in the presentation will be incremented, because we have inserted the same slide in a previous position 

presentation.Slides.RemoveAt(3);               

//Save the Presentation in file system   

presentation.Save("Output.pptx");   

 

Please find the complete sample in below link,
