Hi Sopan,

If I understand your scenario correctly, you are looking for a collapse/expand functionality. RadDocument does not have a mechanism that allows hiding and showing parts of the document, so unfortunately I cannot suggest a way to implement collapsible and expandable regions.

Hi Iva ,

I have added RadExpander  control dynamically to the RadDocument but when I am going to Copy the RadDocument Content with that control (RadExpander), only content is copied not control.

so is there any way to copy all the data from raddocument and seperate it as Control and text ?

Hi Iva 

Is it possible to add a span with some content dynamically to RadDocument Html string (by converting RadDocument to Html using Provider)
and make it invisible so that the expansion button work. If yes the how ?

Hello Sopan,

InlineUIContainers are not copyable elements. Thus, when you copy a part of the document that includes an inline UI container and some text and paste it, only the text will be placed. You can find a more detailed explanation in this forum thread.

When it comes to inserting text in the document, this can be done through the Insert(string text) method of RadRichTextBox and RadDocumentEditor. Having inserted the string, it will naturally be included in the HTML export.

I hope this answers your question.
