Can anyone help me in this regard?

I am doing it using Asp.Net with C# and OpenXML SDK.

Any help? Thanks in anticipation

Hi,

    You can add the slide in whichever position you like. Use the following code to insert the slide in an absolute position.

internal static void InsertSlide(this PresentationPart presentationPart, string layoutName, int absolutePosition)       
{           

            int slideInsertedPostion = 0;            

            UInt32 slideId = 256U;           
           slideId += Convert.ToUInt32(presentationPart.Presentation.SlideIdList.Count());
            Slide slide = new Slide(new CommonSlideData(new ShapeTree()));
            SlidePart sPart = presentationPart.AddNewPart<SlidePart>();           
            slide.Save(sPart);
            SlideMasterPart smPart = presentationPart.SlideMasterParts.First();           
            SlideLayoutPart slPart = smPart.SlideLayoutParts.SingleOrDefault(sl => sl.SlideLayout.CommonSlideData.Name.Value.Equals(layoutName));
            sPart.AddPart<SlideLayoutPart>(slPart);
            sPart.Slide.CommonSlideData = (CommonSlideData)smPart.SlideLayoutParts.SingleOrDefault(sl => sl.SlideLayout.CommonSlideData.Name.Value.Equals(layoutName)).SlideLayout.CommonSlideData.Clone();
            SlideId newSlideId = presentationPart.Presentation.SlideIdList.AppendChild<SlideId>(new SlideId());           
            newSlideId.Id = slideId;           
            newSlideId.RelationshipId = presentationPart.GetIdOfPart(sPart);
            slideInsertedPostion = presentationPart.SlideParts.Count();
            presentationPart.Presentation.Save();
          
            var returnVal = ReorderSlides(presentationPart, slideInsertedPostion - 1, absolutePosition - 1);          
} 

internal static int ReorderSlides(PresentationPart presentationPart, int currentSlidePosition, int newPosition)       
{           
            int returnValue = -1;

            if (newPosition == currentSlidePosition)            {                return returnValue;            }
            int slideCount = presentationPart.SlideParts.Count();
            if (slideCount == 0)            {                return returnValue;            }
            int maxPosition = slideCount - 1;
            CalculatePositions(ref currentSlidePosition, ref newPosition, maxPosition);
            if (newPosition != currentSlidePosition)           
            {               
                   DocumentFormat.OpenXml.Presentation.Presentation presentation = presentationPart.Presentation;               
                   SlideIdList slideIdList = presentation.SlideIdList;
                   SlideId sourceSlide = (SlideId)(slideIdList.ChildElements[currentSlidePosition]);               
                   SlideId targetSlide = (SlideId)(slideIdList.ChildElements[newPosition]);
                   sourceSlide.Remove();
                   if (newPosition > currentSlidePosition)               
                   {                   
                             slideIdList.InsertAfter(sourceSlide, targetSlide);               
                   }               
                   else               
                   {                   
                        slideIdList.InsertBefore(sourceSlide, targetSlide);               
                   }
                   returnValue = newPosition;
            }           
            presentationPart.Presentation.Save();
      return returnValue;       
} 

private static void CalculatePositions(ref int originalPosition, ref int newPosition, int maxPosition)       
{           
        if (originalPosition < 0)           
        {               
              originalPosition = maxPosition;           
        }
        if (newPosition < 0)           
        {               
               newPosition = maxPosition;           
        }
        if (originalPosition > maxPosition)           
        {               
               originalPosition = maxPosition;           
        }           
        if (newPosition > maxPosition)           
        {               
               newPosition = maxPosition;           
        }       
}

You can insert text into a ppt by any of these methods,
1. Have a pre-defined content placeholder/ text placeholder and replace the Run->Text->Value of it.
2. Create a placeholder at run-time and add it to the required slide (In this case, you need to create Run, paragraph, TextBody, Shape..).

You can insert the text into using the first method like this,

internal static void InsertText(this Shape shape, string content)
{     
        DocumentFormat.OpenXml.Drawing.Text textChild = shape.TextBody.GetFirstChild<DocumentFormat.OpenXml.Drawing.Paragraph>().GetFirstChild<DocumentFormat.OpenXml.Drawing.Run>().Text;
      if ((string.IsNullOrEmpty(textChild.InnerText) || string.IsNullOrEmpty(textChild.Text)) && textChild.Text != "")           
      textChild = new DocumentFormat.OpenXml.Drawing.Text(content);      else textChild.Text = content;   
    }  
}

Hope this helps.. 

Hi pramodhegde thanks for ur reply i hope it ill work but i dont know to call the insert function i tryed 3 ways but its showing invalid argument error nu can u help me?

protected void Button2_Click(object sender, EventArgs e)

       {

           InsertNewSlide(@"C:\Prabhu\ppp.pptx","hi amma",3);

       }

       public static void InsertNewSlide(string presentationFile, string slideTitle, int position)

       {

           // Open the source document as read/write.

           using (PresentationDocument presentationDocument = PresentationDocument.Open(presentationFile, true))

           {

               // Pass the source document and the position and title of the slide to be inserted to the next method.

               PresentationPart presentationPart = presentationDocument.PresentationPart;

              InsertSlide(presentationPart, slideTitle, position);

           }

       }

       internal static void InsertSlide(this PresentationPart presentationPart, string layoutName, int absolutePosition)

       {

//ur code

       }

i tryed like this and

protected void Button1_Click(object sender, EventArgs e)

       {

           using (PresentationDocument prstDoc = PresentationDocument.Open(@"C:\Prabhu\ppp.pptx", true))

           {

               slide = prstDoc.PresentationPart.InsertSlide("Title and Content",3);

               Shape shape = slide.CommonSlideData.ShapeTree.Elements<Shape>().FirstOrDefault(

                   sh => sh.NonVisualShapeProperties.NonVisualDrawingProperties.Name.Value.ToLower().Equals("Content Placeholder 2".ToLower()));

               Picture pic = slide.AddPicture(shape, @"C:\Prabhu\amma.jpg");

               slide.CommonSlideData.ShapeTree.RemoveChild<Shape>(shape);

               slide.Save();

               prstDoc.PresentationPart.Presentation.Save();

           }

       }

this also i tryed but same error

Yes. Put these methods in a class which is static (better you keep it within the same namespace).

public static class Extensions

{

   .....// keep all those methods here.

}

Hi,

Thanks u for ur reply ,

In ur old code u r slide insert function is

internal static Slide InsertSlide(this PresentationPart presentationPart, string layoutName)

{

//code

}

here u used Slide Insertslide()

so u called like this

Slide slide=prstDoc.PresentationPart.InsertSlide("Title and Content");

protected void Button1_Click(object sender, EventArgs e)

       {

           using (PresentationDocument prstDoc = PresentationDocument.Open(@"C:\Prabhu\ppp.pptx", true))

           {

               Slide slide = prstDoc.PresentationPart.InsertSlide("Title and Content");

               Shape shape = slide.CommonSlideData.ShapeTree.Elements<Shape>().FirstOrDefault(

                   sh => sh.NonVisualShapeProperties.NonVisualDrawingProperties.Name.Value.ToLower().Equals("Content Placeholder 2".ToLower()));

               Picture pic = slide.AddPicture(shape, @"C:\Prabhu\amma.jpg");

               slide.CommonSlideData.ShapeTree.RemoveChild<Shape>(shape);

               slide.Save();

               prstDoc.PresentationPart.Presentation.Save();

           }

       }

But now we are created in Void so How i can call ur new function

internal static void InsertSlide(this PresentationPart presentationPart, string layoutName, int absolutePosition)

       {

        //new code

       }

Modify the latest code by keeping the last line of the previous code, which actually returns the Slide.

return GetSlide...(..);

So, new method might look like,

internal static Slide InsertSlide(this PresentationPart presentationPart, string layoutName, int absolutePosition)

      {

       //new code

      return GetSlide...(..);

      }

Thank u my dear friend ...........thanks a lot am getting image where i need

i hope ur Text code also work
