Would you please tell me exactly where I can find the RichTextBoxAdv Class Reference documentation in Online Help.
I open the help.syncfusion.com page, then click "Class Reference".
I see two drop-down selectors, so I pick WPF in the left-hand one.
I try various selections from the right-hand selector "Tools", "SFShared" among them.
Then I try to search - and every time I get "0 results found".
My conclusion at this point in time is that the online help does not contain any Class Reference documentation for RichTextBoxAdv.
