It is default constructor for BooleanField.

It offers no functionality but it calls the baseField's default constructor.  

_operator

_operator has been marked as protected just to allow the inheriting classes the ability to change the operator without going through the property set method, which will reset the UseInSearch flag.

		this._operator = " IN ";
		

		this._operator = " = ";
		

Holds a Boolean value that can be used for specifying weather this field can be used in grouped result set or not.

Holds a Boolean value that can be used for specifying weather this field can contain Null values. (Inherited from BaseField)

Holds a Boolean value that can be used for specifying weather this field can be used in updates/inserts or not.

This value doesn't necessarily indicate that the field will be used in the updates/inserts, but if this is true, only then the field's UseInSave property will be used.

This can be useful to the User Interface controls to be able to decide if this field will allow updates or not. (Inherited from BaseField)

Holds a Boolean value that can be used for specifying weather this field can be used in searching resultset or not.

This value doesn't necessarily indicate that the field will be used in the Search criteria, but if this is true, only then the field's UseInSearch property will be used.

This can be useful to the User Interface controls to be able to decide if this field will allow search or not. (Inherited from BaseField)

Holds a Boolean value that can be used for specifying weather this field can contain Null values.

This value doesn't necessarily indicate that the field will be used in the sort, but if this is true, only then the field's Sort property will be used.

This can be useful to the User Interface controls to be able to decide if this field will allow sorting or not. (Inherited from BaseField)

Holds a reference to the business object that contains this field. (Inherited from BaseField)

Returns a Type representation of the .NET type that is equivalent to the underlying database type. (Inherited from BaseField)

This value will be considered equallent to false value.  

GroupPosition can be used to specify the position of the column in the group by clause. (Inherited from BaseField)

Determines weather a field will be used in group by clause and the aggregate function to use (if any). (Inherited from BaseField)

IsCustom

Holds a Boolean value that can be used for specifying weather this field's name is a custom name or not.

If it is set to true the Name property can be assigned any valid sql String. This can be very useful for creating calculated columns in result sets where the calculated column is created by the database server.

	MyField.IsCustom = true;
	

Holds a Boolean value that can be used for checking if the value of this field has been modified since the business object values were loaded last. (Inherited from BaseField)

Holds a Boolean value that can be used for specifying weather this field's current value is Null or not.

When IsNull is set to True the Value is destroyed. (Inherited from BaseField)

List can be used to specify a list of values that are to be used in the search criteria.

This is only used if the SearchMode is set to List or All. (Inherited from BaseField)

Holds this field's actual column name from the database. (Inherited from BaseField)

Operator

Holds a String value that can be used for specifying search operator. Changing the Operator value also set ths UseInSearch property to true. NOTE: Starting version 3.x you can use Operators class that provides constants for each operator that is implemented.

	MyField.Operator = Operators.EqualTo;
	

	MyField.Operator = Operators.NotEqualTo;
	

	MyField.Operator = Operators.Like;
	

Holds a String value that can be used for specifying the result set name (i.e. an alias) for this column.

(Inherited from BaseField)

SearchCondition

Holds a String value that can be used for specifying search condition.

You can use MoreResults property of the business object and that will automatically assign a value to the SearchCondition property. However, by directly changing the value of this property you gain full control over the search critiria.

	MyField.SearchCondition = " AND ";
	

	MyField.SearchCondition = " OR ";
	

SearchMode is used to determine weather the field's where clause will be based on the value, list or all. (Inherited from BaseField)

SearchPostfix

Holds a String value that can be used as postfix to the search criteria for this field.

	MyField.SearchPostfix = " ) ";
	

SearchPrefix

Holds a String value that can be used as prefix to the search criteria for this field.

	MyField.SearchPrefix = " (  ";
	

Determines weather a field will be used in sort and its sort direction. (Inherited from BaseField)

SortPosition can be used to specify the position of the column in the sort order. (Inherited from BaseField)

Holds a IDataParameter value that can be used for specifying the SqlParameter Name.

SqlParam is not serialized and it is also ignored by the xml serialization.

In normal circumstances, there is no need to assign value to this property as it automatically handles it. (Inherited from BaseField)

Holds a String value that can be used for specifying the table name for this field. (Inherited from BaseField)

Holds a String value that can be used for specifying the table's result set name for this field.

This should match with the value of the business objects ResultSetName property.

In normal circumstances, there is no need to assign value to this property as it automatically handles it. (Inherited from BaseField)

This value will be considered equallent to true value.  

Holds a Boolean value that can be used for specifying weather to include this field in specifying the update command. (Inherited from BaseField)

Holds a Boolean value that can be used for specifying weather to include this field in specifying the search criteria. (Inherited from BaseField)

This property if the TrueText and FalseText properties will be used instead of the regular True and False.  

It holds a Boolean value.  

Holds a Boolean value that can be used for specifying weather to include this field in resulting dataset or not. (Inherited from BaseField)

Assigns the Value of this field into the database parameter passed in.

(Inherited from BaseField)

It returns a value that represents a parameter name appropriate for the selected database type. In normal situations it is needed to call this method as all the parameter handeling is done by business objects.
