Add dependency property for showing/hiding the line numbers on the left of the source code.

We could introduce API for customizing the folding region lines and their respective regions. For example, a customization could be hover-coloring of line regions, like in the latest VS:

Currently, the RadSyntaxEditor control does not have an out-of-the-box printing functionality.

Add functionality for precise positioning of the popups inside the RadSyntaxEditor control.

We want to have the option to replace texts only in a selected part of the document. 

Use Notepad++ as a reference to check this feature.

Currently, if you load a big .xml file with big number of tags, the XmlFoldingTagger takes a lot of time to execute its logic. Improve the performance in those situations.

I do have some feedback on this component. I love it, but of course there are some areas where improvement can be made. For instance, in the screenshot below, I have highlighted some words where improvement can be made.

1. ‘1,2,3,5’ – Literals in SSMS are Red
2. ‘ER – 100% OF MEDICARE’ – OF is highlighted in Blue. It is contained in a literal and shouldn’t be highlighted
3. ISNULL – Is a function and should be highlighted in Blue

---- - It looks like that the tagger is only looking for 2 – only. If there are more than 2 in sequence, it doesn’t identify it as a comment and should

We could create intellisense similar to Visual Studio.

Add support for using right-to-left characters. This includes.
    - typing from right to left
    - proper selection, navigation between RTL chars
    - proper insert, delete, cut, copy, paste operations (modifications) sign

Python is one of the most important scripting languages. It would be nice if this language was supported by default.

Hello,

We would like to use SyntaxEditor by providing our own programming language definition. It would be great to have the ability to feed SyntaxEditor with a language definition file. This file could be use an EBNF-like format to provide syntax coloration.

Thanks & regards,

Add API for inserting code snippets like in Visual Studio.
