openxml and powerpoint doubt

i am working on modifying powerpoint presentations using openxml

i m currently stuck in identifying if it is possible to add a bulleted point to

already existing bulleted list in powerpoint slide.

please help!

This code snippet shows some two lines of bullet points with the values 'Hi' and 'INEED TO FIND THIS'. It should give you a idea how the bullet points are added. In your case I guess the .Text will be blank if you jusut wanted an empty bullet point

paragraphProperties51.Append(bulletFont10);

paragraphProperties51.Append(characterBullet10);

A.Run run63 = new A.Run();

A.RunProperties runProperties87 = new A.RunProperties(){ Language = "en-NZ", Dirty = false, SmartTagClean = false };

A.Text text87 = new A.Text();

text87.Text = "Hi";

run63.Append(runProperties87);

run63.Append(text87);

paragraph102.Append(paragraphProperties51);

paragraph102.Append(run63);

A.Paragraph paragraph103 = new A.Paragraph();

A.ParagraphProperties paragraphProperties52 = new A.ParagraphProperties(){ LeftMargin = 285750, Indent = -285750 };

A.BulletFont bulletFont11 = new A.BulletFont(){ Typeface = "Arial", PitchFamily = 34, CharacterSet = 0 };

A.CharacterBullet characterBullet11 = new A.CharacterBullet(){ Char = "•" };

paragraphProperties52.Append(bulletFont11);

paragraphProperties52.Append(characterBullet11);

A.Run run64 = new A.Run();

A.RunProperties runProperties88 = new A.RunProperties(){ Language = "en-NZ", Dirty = false, SmartTagClean = false };

A.Text text88 = new A.Text();

text88.Text = "INEED TO FIND THIS";

run64.Append(runProperties88);

run64.Append(text88);

Hi Andrewla,

In the example you have mention above you have created new charecterbullets and bulletsfont. Which it quite easy.

What if we need to use existing bullets in slides and add a new point with this existing bullet.

Can u help me on this.

Thanks,

Pranay

Hi Mandar,

Some how I manage to do the same as you required.

Below is the code for the same.

---------------------------------------------------------

static void Main(string[] args)

       {

     string pptfilepath = @"D:\openxml\POCs\testppts\testSample\text.pptx";

   using (PresentationDocument pDoc = PresentationDocument.Open(pptfilepath1, true))

           {

               PresentationPart pPart = pDoc.PresentationPart;

               SlidePart sdl = pPart.GetSlidePartsInOrder().First();

                 AddBullets(sdl, "add with existing bulleted points");

           }

       }

public static void AddBullets(SlidePart slidePart1, string textToAppend)

       {

           Slide slide1 = slidePart1.Slide;

           CommonSlideData commonSlideData1 = slide1.GetFirstChild<CommonSlideData>();

           ShapeTree shapeTree1 = commonSlideData1.GetFirstChild<ShapeTree>();

           Shape shape1 = shapeTree1.GetFirstChild<Shape>();

           TextBody textBody1 = shape1.GetFirstChild<TextBody>();

           A.Paragraph paragraph1 = textBody1.GetFirstChild<A.Paragraph>();

           A.CharacterBullet Charbullets = (A.CharacterBullet)paragraph1.ParagraphProperties.OfType<A.CharacterBullet>().First().Clone();

           A.BulletFont bulletsfonts = (A.BulletFont)paragraph1.ParagraphProperties.OfType<A.BulletFont>().First().Clone();

           A.Paragraph paragraph2 = new A.Paragraph();

           A.ParagraphProperties paragraphProperties1 = new A.ParagraphProperties();

           paragraphProperties1.Append(bulletsfonts);

           paragraphProperties1.Append(Charbullets);

           A.Run run = new A.Run();

           A.RunProperties runProperties = new A.RunProperties() { Language = "en-US", SmartTagClean = false };

           A.Text text = new A.Text();

           text.Text = textToAppend;

           run.Append(runProperties);

           run.Append(text);

           A.EndParagraphRunProperties endParagraphRunProperties1 = new A.EndParagraphRunProperties() { Language = "en-US", Dirty = false };

           paragraph2.Append(paragraphProperties1);

           paragraph2.Append(run);

           paragraph2.Append(endParagraphRunProperties1);

           textBody1.Append(paragraph2);

           slide1.Save();

       }

-------------------------------------------------------

Note: your ppt slide shoul have at leat one bullted text in text box.

Enjoy,

Hi,     
     To add an item to the existing list, you have to add a Paragraph object to the existing TextBody.
      I have attached a sample solution. Please have a look.

Hi Pramod,

Yes you r right.

Even, I did the same in the above example.
