Hides the active editor saving any changes made.
Cell values are edited by editors from the DevExpress Editors Library or their descendants. Unlike the VGridControlBase.HideEditor method which simply closes the active editor, the CloseEditor method also saves the changes made to the edited cell's content. This method can be useful, for instance, when you need to close the text editor and to save its contents when the input string length reaches a predefined value.
The CloseEditor method is automatically called when the end-user accepts the edited value.
