// Developer Express Code Central Example:
// How to display rich text in GridView's cells, but edit their content in a popup window
// 
// This example demonstrates how to provide different editors for displaying and
// editing data. In this scenario, cells values can be edited using the
// RichEditControl located in the popup window. However, the
// RepositoryItemRichTextEdit is used to display cells content when their in-place
// editor is closed.
//
