public override void ExtractValuesFromCell (System.Collections.Specialized.IOrderedDictionary dictionary, System.Web.UI.WebControls.DataControlFieldCell cell, System.Web.UI.WebControls.DataControlRowState rowState, bool includeReadOnly);
override this.ExtractValuesFromCell : System.Collections.Specialized.IOrderedDictionary * System.Web.UI.WebControls.DataControlFieldCell * System.Web.UI.WebControls.DataControlRowState * bool -> unit
Public Overrides Sub ExtractValuesFromCell (dictionary As IOrderedDictionary, cell As DataControlFieldCell, rowState As DataControlRowState, includeReadOnly As Boolean)

The ExtractValuesFromCell method is implemented by types derived from DataControlField, such as TemplateField. This method is called to extract the values of two-way data-bound fields in the template to populate dictionaries to be passed to the data source for an update, insert, or delete operation. The field/value pair is stored in the dictionary collection that is passed to the method. The ExtractValuesFromCell method is called by the ExtractRowValues method of data controls such as DetailsView and GridView.
