I use the following (slightly modified) code, but most of the shapes (if not all) don’t get the formating of the layout (background color, etc). It seems that I can’t remove all of the old placeholders either (so, I get a textbox and there is the placeholder shape behind it…) :
PresentationEx presentation = new PresentationEx(@“C:\Users\User\Desktop\Template.pptx”);
//PresentationEx presentation = new PresentationEx();
presentation.UpdateDateTimeFields = true;
foreach (LayoutSlideEx layout in presentation.Masters[0].LayoutSlides)
{
int at = presentation.Slides.AddEmptySlide(layout);
SlideEx slide = presentation.Slides[at];
for (int i = 0; i < slide.Shapes.Count; i++) slide.Shapes.RemoveAt(0);
<span style="color:blue;">foreach</span> (<span style="color:#2b91af;">ShapeEx</span> shape <span style="color:blue;">in</span> slide.LayoutSlide.Shapes)

But the new shapes go to the right place without any placement code and this makes me curious.
Why doesn’t this work right???
