How to add content to Slide which gets pulled from the server

Aspose.Slides Product Family

Hi Team,


We have been using Aspose to create word documents and PPT presentations from .Net. We have been using images with source specified as absolute server URLs (as explained in this URL - https://forum.aspose.com/t/97735) so that the documents/ppt slides show updated images each time the image is updated on the server. So far so good. Now we need a way where we can also pull the textual content from the server, so that each time the content is updated on the server, the word document/ppt slide shows the updated content. Is there any way to achieve this?

Hi Haresh,

Thanks for getting back to us.

I have observed your comments and like to share that Aspose.Slide allows to add the slides and text inside the presentation no matter from which source the text arrives. You need to devise mechanism on your end to fetch the textual information from your source and then use either Aspose.Words or Aspose.Slides to populate that text in Word or PowerPoint presentation respectively as per your convenience using standard API methods. Please try using following sample code to serve the purpose on your end.

Many Thanks,

Hi Mudassir,


Thanks for the prompt response. It was indeed helpful to visit the link shared by you. What we wanted to achieve is explained in the steps below for better understanding (we are using ASP.NET):
  1. Create an PPT presentation using Aspose.Slides.
  2. Add some image placeholders to it with some absolute URLs.
  3. Add some text blocks to it with some absolute URLs.
  4. Save the PPT presentation.
  5. Download the presentation.
  6. When the user opens the downloaded presentation, the images are pulled from the server as the URL specified is a web URL, so when the images change on the server, we see new images in the downloaded file as well. (This is already implemented and is working fine)
  7. The text for the PPT is also pulled from the server. So when the text changes are done on the server, the PPT file which was downloaded earlier too has the latest updated content without forcing the user to download a fresh copy of the PPT file (This is what we wish to achieve.)
Hope the above steps would give a better understanding of our requirement.

Hi Haresh,

I have observed your requirement and like to share that in case of image you set the path of image as URL. So, when you load the presentation the images are loaded from the URL. However, this is not applicable in case of text as text is set in text frames and there is no option of linked test even in PowerPoint. The approach that you can adopt on your end is to update the text in the desired fields as soon as it gets changed on your server and you generate the presentation based on updated data in server. There is no option of run time changing of text. Even in PowerPoint the requested support is not possible. If you are able to use achieve this using PowerPoint then please share with us and I may add that as investigation in our issue tracking system.

Many Thanks,

Thanks for the response Mudassir.


Can we have kind of an iFrame in the PPT, which has a web URL linked to it, from where we can fetch data?

Hi Haresh,

I have discussed the possibility of linked text frame in Aspose.Slides with our development team and regret to share that there is no such option available in PowerPoint even to achieve this. The requested support is not possible using Aspose.Slides as well as PowerPoint. You may please devise some alternative approach on your end to achieve the goal.

Many Thanks,
