I want to place in a cell of the table my UserControl. I understand that for this purpose it is necessary to realise interface IProvidesEmbeddableEditor. Prompt please as to me it to make?
With the release of 9.2, the ControlContainerEditor is available to support putting custom controls within the cells of an UltraGrid. Prior to 9.2, you will have to implement the IProvidesEmbeddableEditor interface, as you mentioned, which is not trivial; the closest example is the C# RichTextEditor sample that ships with the product samples, or if you have the source code take a look at how some of the editors are implemented. This is generally not worth implementing since it could take you at least several days to properly implement this interface, which is why the ControlContainerEditor was created.
