Cannot change value for content control of type rich text box with Level = MarkupLevel.Inline

[long.nguyen2]

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.

}
