    'Usage
 

    Dim instance As CellEditorContext

[NameScopeProperty("NameScope", System.Windows.NameScope)]
public class CellEditorContext : System.Windows.DependencyObject
    Remarks
    Whether a foreign key constraint or enum is automatically detected or manually provided, the end result is that a ComboBox is used to edit the content of the corresponding cell unless a cell editor has been explicitly provided, in which case, the provided cell editor will be used. Cell editors that are created to edit foreign key constraints can access information about their parent cell, such as the CellContentTemplate to use, through the CellEditorContext attached property (see Example).
