I have code for updating URL. but if I set link.Text then its not working.
if (obj is PdfTextWebLinkAnnotationWidget)
{
PdfTextWebLinkAnnotationWidget link = obj as PdfTextWebLinkAnnotationWidget;
link.Url = "#";
//link.Text = "Click Here";//This is not working
}

Thank you,

Dear Kiran,

Thanks for your inquiry.
Sorry that at present Spire.PDF doesn’t support to update text of the Hyperlink. But there is a method covering new text on it to achieve your target, simple code for your reference:

Code: Select all

            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(@"F:\testing\pdf form testing\original document\6363.pdf");
            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 10, FontStyle.Underline));
            PdfSolidBrush brush = new PdfSolidBrush(Color.Blue);
            //find the text you want to change and then cover new text on it
            foreach (PdfPageBase page in doc.Pages)
            {
                PdfTextFindCollection loFinds = page.FindText("Hello world");
                foreach (PdfTextFind lofind in loFinds.Finds)
                {
                    page.Canvas.DrawRectangle(new PdfSolidBrush(Color.White), lofind.Bounds);
                    page.Canvas.DrawString("updated text", font, brush, new PointF(lofind.Bounds.X, lofind.Bounds.Y));
                }
            }
            doc.SaveToFile("6363res.pdf");

If there is any question, welcome to get it back to us.

Hello Support,

Thanks for your quick response.

Your code is working fine. But it will not help to me.
Because I have to replace URL and Text of hyperlink.

I can't be able to place covering new text exactly on hyperlink because of
1> link.Text returns = "" (So can't find link based on text)
2> link.Location returns {X = 0.0 Y = 0.0}. (location returns 0)

Also what is the use of (PdfTextWebLinkAnnotationWidget) link.SetText()?

Thank you,
Kiran

Dear Kiran,

You need to know hyperlink text in advance, and then find it and cover it. Sorry that at present there is no way to find hyperlink text programmatically. The link.SetText() is used to set the name of the filed. It is not used to update the hyperlink text.
