Introducing a way to replace text with other document elements.


To achieve this we will iterate the document elements of type Run and will compare their text with the desired string. If there is a match we will store the Run index and we will insert the desired element (in our example: Break on this specific index in the Inlines collection. Finally we will remove the Run.

RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document); 
editor.InsertText("First line"); 
editor.InsertText("Second line"); 
foreach (Run run in document.EnumerateChildrenOfType<Run>().ToList()) 
    if (run.Text == "NewLine") 
        Paragraph paragraph = run.Paragraph; 
        int childIndex = paragraph.Inlines.IndexOf(run); 
        Break br = new Break(document); 
        br.BreakType = BreakType.LineBreak; 
        paragraph.Inlines.Insert(childIndex, br);
