SfRichTextBoxAdv - Get the Inline/SpanAdv of the selection

[Jimmi Day]

Is there a way to get the Inline or SpanAdv object of the selected text in a SfRichTextBoxAdv ?

I would like to let the user select text and press a button, when pressed i want to add the selected inline to a collection.

Later on i want to change the text in these inlines by casting them to a SpanAdv and setting their Text property.

Hi Jimmi,

Thank you for contacting Syncfusion support.

Our SfRichTextBoxAdv control supports API to insert/modify the text at current selection by using ‘InsertText’ method of ‘SelectionAdv’ class. As we mentioned in the forum #135190, you can preserve the ‘TextPosition’ at selection using hierarchical index and convert it back as ‘TextPosition’ using ‘GetTextPosition’ API of ‘DocumentAdv’. Then you can update the selection with the retrieved ‘TextPosition’ instances and then modify the text using above mentioned ‘InsertText’ API.
