How to: Insert RTF text to a document

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T532651.

Currently, ASPxRichEdit doesn't provide a functionality to insert RTF formatted text on the client side so that this format is applied automatically. This example demonstrates a workaround that allows you to insert formatted RTF text to the current document on a button click via an ASPxRichEdit callback.

To implement this scenario, initiate an ASPxRichEdit custom callback via the client-side ASPxClientRichEdit.PerformCallback method and handle the server-side ASPxRichEdit.Callback event. To add the required text in this event handler, you can use the AppendRtfText method of our non-visual RichEditDocumentServer component.
To insert this text at the current caret position in the middle of a document text, obtain this position on the client side by using the RichEditSelection.intervals array object and pass it to the server as a parameter of the ASPxClientRichEdit.PerformCallback method. Then, access this passed value in the server-side Callback event handler and use it to modify the current document position via the Document.CreatePosition method before inserting RTF text.
