Class DataBindingItem - West Wind Toolkit for .NET

Class DataBindingItem

An individual binding item. A BindingItem maps a source object - a property/field or database field - to a property of a Control object.

The object is a child for the DataBinder object which acts as a master object that performs the actual binding of individual BingingItems.

Binding Items can be attached to controls and if the control implements the IDataBinder.

Note: This class inherits from Component so the designer can properly render the item as an extender control.

Class Members

Member		Description
	Constructor	Default Constructor
	Validate	Use this event to hook up special validation logic. Called after binding completes. Return false to indicate validation failed
	DataBind	Binds a source object and property to a control's property. For example you can bind a business object to a the text property of a text box, or a DataRow field to a text box field. You specify a binding source object (Customer.Entity or Customer.DataRow) and property or field(Company, FirstName) and bind it to the control and the property specified (Text). public void DataBind() public void DataBind(Control container)
	OnValidate	Fires the Validation Event public bool OnValidate()
	ToString	Returns a the control bindingsource and binding source member public virtual string ToString()
	Unbind	Unbinds control properties back into the control source. public void Unbind() public void Unbind(Control BindingContainerControl)
	Binder	Reference to the DataBinder parent object.
	BindingErrorMessage	An error message that gets set if there is a binding error on the control. If this value is pre-set this value is used instead of an auto-generated message
	BindingMode	Determines how databinding and unbinding is done on the target control. One way only fires DataBind() and ignores Unbind() calls. Two-way does both. None effectively turns off binding.
	BindingProperty	Property that is bound on the target controlId
	BindingSource	The binding source object that is the source for databinding. This is an object of some sort and can be either a real object or a DataRow/DataTable/DataSet. If a DataTable is used the first row is assumed. If a DataSet is used the first table and first row are assumed.
	BindingSourceMember	The property or field on the Binding Source that is bound. Example: BindingSource: Customer.Entity BindingSourceMember: Company
	BindingSourceObject	An instance of the object that the control is bound to Optional - can be passed instead of a BindingSource string. Using a reference is more efficient. Declarative use in the designer always uses strings, code base assignments should use instances with BindingSourceObject.
	ControlId	The ID of the control to that is bound.
	ControlInstance	An optional instance of the control that can be assigned. Used internally by the DataBindiner to assign the control whenever possible as the instance is more efficient and reliable than the string name.
	DisplayFormat	Format Expression ( {0:c) ) applied to the binding source when it's displayed. Watch out for two way conversion issues when formatting this way. If you create expressions and you are also saving make sure the format used can be saved back.
	EnableViewState
	ErrorMessageLocation	Determines how binding and validation errors display on the control
	HtmlEncode	Determines whether the content displayed is Html encoded to prevent script injection
	ID
	IsBindingError	Internal property that lets you know if there was binding error on this control after binding occurred
	IsRequired	If set requires that the control contains a value, otherwise a validation error is thrown Useful mostly on TextBox controls only.
	UnboundValue	The value that is to be assigned to the control after unbinding.
	UserFieldName	A descriptive name for the field used for error display
	Visible
