Hyperlink

Demonstrates adding, accessing, removing, and updating hyperlinks on shapes using Aspose.Slides for .NET.

Add a Hyperlink

Create a rectangle shape with a hyperlink pointing to an external website.

static void Add_Hyperlink()
{
    using var pres = new Presentation();
    var slide = pres.Slides[0];
    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
    shape.TextFrame.Text = "Aspose";
    shape.TextFrame.Paragraphs[0].Portions[0].PortionFormat.HyperlinkClick = new Hyperlink("https://www.aspose.com");
}

Access a Hyperlink

Read hyperlink information from a shape’s text portion.

static void Access_Hyperlink()
{
    using var pres = new Presentation();
    var slide = pres.Slides[0];
    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
    shape.TextFrame.Text = "Aspose";
    shape.TextFrame.Paragraphs[0].Portions[0].PortionFormat.HyperlinkClick = new Hyperlink("https://www.aspose.com");

    var hyperlink = shape.TextFrame.Paragraphs[0].Portions[0].PortionFormat.HyperlinkClick;
}

Remove a Hyperlink

Clear the hyperlink from a shape’s text.

static void Remove_Hyperlink()
{
    using var pres = new Presentation();
    var slide = pres.Slides[0];
    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
    shape.TextFrame.Text = "Aspose";
    shape.TextFrame.Paragraphs[0].Portions[0].PortionFormat.HyperlinkClick = new Hyperlink("https://www.aspose.com");

    shape.TextFrame.Paragraphs[0].Portions[0].PortionFormat.HyperlinkClick = null;
}

Update a Hyperlink

Change the target of an existing hyperlink. Use HyperlinkManager to modify text that already contains a hyperlink, which mimics how PowerPoint updates hyperlinks safely.

static void Update_Hyperlink()
{
    using var pres = new Presentation();
    var slide = pres.Slides[0];
    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
    shape.TextFrame.Text = "Aspose";
    var portion = shape.TextFrame.Paragraphs[0].Portions[0];
    portion.PortionFormat.HyperlinkClick = new Hyperlink("https://old.example.com");

    // Changing a hyperlink inside existing text should be done via
    // HyperlinkManager rather than setting the property directly.
    // This mimics how PowerPoint safely updates hyperlinks.
    portion.PortionFormat.HyperlinkManager.SetExternalHyperlinkClick("https://new.example.com");
}
