RadRichTextEditor: Memory leak in the WatermarkUIProvider when adding new documents

When adding a new document to the same instance of a RichTextEditor, the UIProviderRegistry instance of the RichTextBox will keep a dictionary entry for a SectionLayoutBox that contains a reference to a non cleaned up WaterMarkUiProvider.

This SectionLayoutBox in turn has a reference to a DocumentLayoutBox (parent) which has a reference to an old document instance.


A new dictionary entry is added and (retained) for every document loaded.


Disposing the old document makes no difference.

Hello Florens,

Thank you for the detailed explanation. I was able to reproduce the case where WaterMarkUiProvider instances are remaining in the memory. I have approved this item and updated your Telerik points accordingly. 

Unfortunately, I cannot suggest a workaround for this issue.

Thank you for your understanding.
