The ExtractValuesFromCell method is a helper method used to retrieve the values of the fields from the specified DataControlFieldCell object in an ImageField object.


This method is used primarily by control developers.

This method does not have a return value. Instead, the field values are returned by reference through the IOrderedDictionary object passed in for the dictionary parameter. After the method has been called, iterate through the IOrderedDictionary object to access the field values.


To include the read-only field values in the DataControlFieldCell object, pass in true for the includeReadOnly parameter.
