  • PasteFormatting: Pastes the currently copied formatting on the current selection.

Copying and Pasting Formatting

this.radRichTextEditor1.RichTextBoxElement.CopyFormatting();

DocumentPosition start = new DocumentPosition(this.radRichTextEditor1.Document.CaretPosition);
DocumentPosition end = new DocumentPosition(start);

start.MoveToFirstPositionInDocument();
end.MoveToEndOfDocumentElement(start.GetCurrentParagraphBox().AssociatedParagraph);

this.radRichTextEditor1.Document.Selection.SetSelectionStart(start);
this.radRichTextEditor1.Document.Selection.AddSelectionEnd(end);

this.radRichTextEditor1.RichTextBoxElement.PasteFormatting();

Me.radRichTextEditor1.RichTextBoxElement.CopyFormatting()
Dim start As DocumentPosition = New DocumentPosition(Me.radRichTextEditor1.Document.CaretPosition)
Dim [end] As DocumentPosition = New DocumentPosition(start)
start.MoveToFirstPositionInDocument()
[end].MoveToEndOfDocumentElement(start.GetCurrentParagraphBox().AssociatedParagraph)
Me.radRichTextEditor1.Document.Selection.SetSelectionStart(start)
Me.radRichTextEditor1.Document.Selection.AddSelectionEnd([end])
Me.radRichTextEditor1.RichTextBoxElement.PasteFormatting()

The example uses the DocumentPosition and DocumentSelection APIs to create different positions and select content. More information about these APIs is available in the Positioning and Selection topics.
