Throws:

• Exception propertyName is neither a valid property of a control nor an empty string ("").

• ArgumentException The property given by propertyName does not exist on the control.

Binding(propertyName, dataSource, dataMember, formattingEnabled)

Initializes a new instance of the Binding class that binds the indicated control property to the specified data member of the data source, and optionally enables formatting to be applied.

Throws:

• ArgumentException The property given by propertyName does not exist on the control; or the property given is a read-only property.

• Exception Formatting is disabled and propertyName is neither a valid property of a control nor an empty string ("").

Initializes a new instance of the Binding class that binds the specified control property to the specified data member of the specified data source. Optionally enables formatting and propagates values to the data source based on the specified update setting.

Throws:

• ArgumentException The property given by propertyName does not exist on the control; or the data source or data member or control property specified are associated with another binding in the collection.

Initializes a new instance of the Binding class that binds the indicated control property to the specified data member of the specified data source. Optionally enables formatting, propagates values to the data source based on the specified update setting, and sets the property to the specified value when a DBNull is returned from the data source.

Throws:

• ArgumentException The property given by propertyName does not exist on the control; or the data source or data member or control property specified are associated with another binding in the collection.

Initializes a new instance of the Binding class that binds the specified control property to the specified data member of the specified data source.

Throws:

• ArgumentException The property given by propertyName does not exist on the control; or the data source or data member or control property specified are associated with another binding in the collection.
