Getting stream for SlideLayoutPart of a slide.

[princraiParticipant]

Hi Eric,
I am creating a empty slide with one blank slide and in that I create a layout part using the below fucntion.
private static SlideLayoutPart CreateSlideLayoutPart(SlidePart slidePart)
{
SlideLayoutPart slideLayoutPart1 = slidePart.AddNewPart<SlideLayoutPart>(“rId1”);
Presentation.SlideLayout slideLayout = new Presentation.SlideLayout(
new Presentation.CommonSlideData(new Presentation.ShapeTree(
new Presentation.NonVisualGroupShapeProperties(
new Presentation.NonVisualDrawingProperties() { Id = (UInt32Value)1U, Name = “” },
new Presentation.NonVisualGroupShapeDrawingProperties(),
new Presentation.ApplicationNonVisualDrawingProperties()),
new Presentation.GroupShapeProperties(new TransformGroup()),
new Presentation.Shape(
new Presentation.NonVisualShapeProperties(
new Presentation.NonVisualDrawingProperties() { Id = (UInt32Value)2U, Name = “” },
new Presentation.NonVisualShapeDrawingProperties(new ShapeLocks() { NoGrouping = true }),
new Presentation.ApplicationNonVisualDrawingProperties(new Presentation.PlaceholderShape())),
new Presentation.ShapeProperties(),
new Presentation.TextBody(
new BodyProperties(),
new ListStyle(),
new Paragraph(new EndParagraphRunProperties()))))),
new Presentation.ColorMapOverride(new MasterColorMapping()));
slideLayoutPart1.SlideLayout = slideLayout;
return slideLayoutPart1;
}

But when I do slideLayoutPart1.GetStream() it gives empty stream. and hence when I try to integrate with powerpointbuilder for my features and try to use slideLayoutPart1.GetXDocument() it is empty. Can you suggest how can I make sure slideLayoutPart1.GetXDocument() works correct. One way is I create a string and feed that string to slideLayoutPart1. But can there is any easy way I can leverage the above function and also get the stream .

Thanks,
Prince

Hi,

I have never tried to create a slide from scratch. Instead, my approach is to create a one-slide presentation with the slide as I desire it, and then integrate the slide using PresentationBuilder, and then if necessary modify the slide after PresentationBuilder is done with it.

When you create a part, it is initially empty, but you can get the XDocument, then modify it. Following is the code to create a new comments part, and the initialize the XDocument.

    mainPart.AddNewPart<WordprocessingCommentsPart>();

newComments = mainPart.WordprocessingCommentsPart.GetXDocument();

    newComments.Declaration.Standalone = "yes";

newComments.Declaration.Encoding = “UTF-8”;

    newComments.Add(new XElement(W.comments, NamespaceAttributes));

commentNumber = 1;
