Error “cannot insert a node of this type at this location” is shown when changing value for content control of type rich text box with Level = MarkupLevel.Inline. Please see more details in the attachment.

if (sdt.Level == MarkupLevel.Inline && string.Equals(sdt.Title, "ANNEX_INSTRUMENT", StringComparison.InvariantCultureIgnoreCase))
{
    sdt.RemoveAllChildren();
    Paragraph para1 = new Paragraph(doc);
    Run run1 = new Run(doc);
    run1.Text = txtText.Text;
    para1.Runs.Add(run1);
    sdt.ChildNodes.Add(para1); => error with this line.
}

Hi there,

Thanks for your inquiry.

Please use following highlighted code snippet to fix the shared issue and let us know if you have any more queries.

Document doc = new Document(wordFilePath);

    foreach (StructuredDocumentTag sdt in doc.GetChildNodes(NodeType.StructuredDocumentTag, true))
    {
        if (sdt.SdtType == SdtType.RichText)
        {
            if (sdt.Level == MarkupLevel.Block && string.IsNullOrWhiteSpace(sdt.Title))
            {
                sdt.RemoveAllChildren();
                Paragraph para1 = new Paragraph(doc);
                Run run1 = new Run(doc);
                run1.Text = txtText.Text;
                para1.Runs.Add(run1);
                sdt.ChildNodes.Add(para1);
            }
            if (sdt.Level == MarkupLevel.Inline && string.Equals(sdt.Title, "ANNEX_INSTRUMENT", StringComparison.InvariantCultureIgnoreCase))
            {
                sdt.RemoveAllChildren();
                Run run1 = new Run(doc);
                run1.Text = txtText.Text;
                sdt.ChildNodes.Add(run1);
            }
        }
