How to replace date field with some text in the ViewMaster (Vertical) for word/pdf using Aspose?-CodePudding

Aspose code is inserting Viewmaster(vertical) with default date to select as a text inside. I want to replace with some text as shown in the image.

Followed the code mentioned in

CodePudding user response：

Date is set in structured document tag. You can use code like this to get and modify value of this SDT:

// Get structured document tags from footer.
NodeCollection tags = doc.FirstSection.HeadersFooters[HeaderFooterType.FooterPrimary].GetChildNodes(NodeType.StructuredDocumentTag, true);
foreach (StructuredDocumentTag tag in tags)
{
    if (tag.Title.Equals("Date") && tag.SdtType == SdtType.Date)
    {
        tag.IsShowingPlaceholderText = false;
        tag.FullDate = DateTime.Now;
        // By default SDT is minded to XML. We can simply remove mapping to use value set in FullDate property.
        tag.XmlMapping.Delete();
    }
}

If you do not need date, but need to insert some custom text, you can remove the tag and insert a simple paragraph with text instead. For example:

// Get structured document tags from footer.
NodeCollection tags = doc.FirstSection.HeadersFooters[HeaderFooterType.FooterPrimary].GetChildNodes(NodeType.StructuredDocumentTag, true);
foreach (StructuredDocumentTag tag in tags)
{
    if (tag.Title.Equals("Date") && tag.SdtType == SdtType.Date)
    {
        // Put an empty paragraph ater the structured document tag
        Paragraph p = new Paragraph(doc);
        tag.ParentNode.InsertAfter(p, tag);
        // Remove tag
        tag.Remove();
        // move DocumentBuilder to the newly inserted paragraph and insert some text.
        builder.MoveTo(p);
        builder.Write("This is my custom vertical text");
    }
}
