clsWebDateTimeEditorBinder

This binder adapts the modern Infragistics Infragistics.Web.UI.EditorControls.WebDateTimeEditor control generation to SAIF object binding, replacing the classic WebDateTimeEdit path for pages that use the newer editor family. It supports multiple projection modes (Date, Text, or Value), preserves a special string-target writeback behavior added to avoid a noon-display regression, and participates in the shared event, reflection, and validation pipeline inherited from clsObjectBinderBase.

Purpose

• Bind a modern Infragistics date-time editor to business-object properties in either date-oriented or text-oriented workflows.
• Preserve the library's later fix that keeps string-target object-to-control updates on the editor value path instead of forcing text formatting.
• Reuse inherited validation and change-event wiring while specializing date/time conversion behavior.

Context

• Namespace: SAIF.Presentation.Web.Binding
• Assembly/package: SAIF.Presentation.Web.Binding.Infragistics103 (embedded/bundled as source, not independently packaged)

Public members

Member	Signature	Purpose
TargetTypeIsString	Property TargetTypeIsString As Boolean	Selects whether control-to-object updates persist the editor value as a string-target payload or as a Date value.
BindProperty	Property BindProperty As String	Names the business-object property synchronized with the editor.
BindSource	Property BindSource As Object	Supplies the object being edited and validated.
WebDateTimeEditor	Property WebDateTimeEditor As WebDateTimeEditor	Attaches the modern date-time editor control that this binder drives.
Init()	Overrides Sub Init()	Wires the editor ValueChanged event for immediate reverse binding when enabled.
ObjectToControl()	Overrides Function ObjectToControl() As Boolean	Projects the source property into the editor Date, Text, or Value channel based on ControlBindProperty.
New()	Sub New()	Defaults the binder to ControlBindProperty.Value mode.

Inherited public members

Member	Signature	Purpose	Origin
ContainsError	ReadOnly Property ContainsError As Boolean	Set by GetErrors()/validation processing; when true, Validate()/RefreshValidation() counts this binder toward the overall invalid result and its control receives error-state CSS via SetControlFormat().	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
IsDualBinding	ReadOnly Property IsDualBinding As Boolean	When true, ObjectToControl()/ControlToObject() read and write the display object/property while GetErrors() checks a separate validation object/property, as configured by AddDualBinder().	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
ControlPadding	Property ControlPadding As PadArgs	When UsePadding is enabled, pads or trims the value written to the control during ObjectToControl(), so fixed-width display formatting is applied without changing the underlying object value.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
ObjectPadding	Property ObjectPadding As PadArgs	When UsePadding is enabled, pads or strips padding from the value written back to the bound property during ControlToObject(), so stored data is not polluted with display-only padding characters.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
UsePadding	Property UsePadding As Boolean	Enables the ControlPadding/ObjectPadding transforms during ObjectToControl()/ControlToObject(); when false, values pass through unpadded regardless of the padding arguments configured.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
UseEvents	Property UseEvents As Boolean	When true, Init() wires the control's native change event so a user edit immediately calls ControlToObject() instead of waiting for an explicit BindToObject()/Validate() call.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
ControlErrors	ReadOnly Property ControlErrors As ArrayList	Holds the error text GetErrors() collects from the bound object's IDataErrorInfo implementation; Validate() aggregates these strings into the consolidated ErrorLabel/SAIFMessage output.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
BindType	Property BindType As BindTypes	Determines which of ObjectToControl()/ControlToObject() actually run during DataBind()/BindToObject(), controlling whether this binder is push-only, pull-only, both, or validation-only.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
FormControl	Overridable Property FormControl As WebControl	Setting this property runs ProcessControl, which applies binder-specific control setup (event wiring readiness, CSS baseline) before the control participates in binding and validation passes.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
FormControlID	Overridable ReadOnly Property FormControlID As String	Supplied to Update() and error-focus logic to locate this binder's control instance on the page without holding a direct control reference.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
Init()	MustOverride Sub Init()	Called once during AddBinder() registration; each concrete binder overrides this to hook the native control event needed for event-driven ControlToObject() and to perform any control-specific setup.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
ObjectToControl()	MustOverride Function ObjectToControl() As Boolean	Invoked by DataBind() for binders configured as ObjectToControl/TwoWay; each concrete binder overrides this to translate the bound property's value into the control-specific display state.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
ControlToObject()	Protected Friend MustOverride Sub ControlToObject()	Invoked by BindToObject() for binders configured as ControlToObject/TwoWay; each concrete binder overrides this to convert the control's current value back into the bound property's type.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
SetControlFormat(inValid As Boolean)	Protected Friend Overridable Sub SetControlFormat(inValid As Boolean)	Called by Validate()/RefreshValidation() after error collection; sets the control's CssClass to the valid/error color per BR-BIND-001, BR-BIND-002, and BR-BIND-003, giving the reader a visual cue of validation state.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
GetErrors()	Protected Friend Overridable Sub GetErrors()	Reads the bound object's IDataErrorInfo.Item(property) during Validate()/RefreshValidation() and appends any non-empty message to ControlErrors, driving both ContainsError and the consolidated error display.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
GetObjectValueAsString(inBizObject, inPropertyName)	Function GetObjectValueAsString(inBizObject As Object, inPropertyName As String) As String	Used by ObjectToControl() to fetch the bound property's current value as display-ready text, applying ObjectPadding/ControlPadding first when UsePadding is enabled.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
GetObjectValue(inBizObject, inPropertyName)	Function GetObjectValue(inBizObject As Object, inPropertyName As String) As Object	Used by ObjectToControl() and type-sensitive binders to fetch the bound property's value in its native CLR type, before any control-specific conversion or formatting.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
SetObjectValueAsString(inBizObject, inPropertyName, inValue)	Protected Function SetObjectValueAsString(inBizObject As Object, inPropertyName As String, inValue As String) As Boolean	Used by ControlToObject() to write a control-derived string back onto the bound property, applying padding/trim rules first when UsePadding is enabled, so the object receives a correctly formatted value.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
SetObjectValue(inBizObject, inPropertyName, inValue)	Protected Function SetObjectValue(inBizObject As Object, inPropertyName As String, inValue As Object) As Boolean	Used by ControlToObject() to write a converted, strongly typed value back onto the bound property, bypassing string formatting for binders that perform their own type conversion.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
ValidationKey	Friend Overridable ReadOnly Property ValidationKey As String	Computed by AddBinder() to key the bound object into m_ValidationObjects per BR-BIND-006, ensuring repeated Validate() passes re-check the correct distinct object.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase
IsSAIFFrameWorkObject	Friend Overridable ReadOnly Property IsSAIFFrameWorkObject(Optional inObj As Object) As Boolean	Detects SAIF framework objects by walking the CLR base-type chain for clsBusinessBase/clsBusinessCollectionBase.	SAIF.Presentation.Web.Binding.Infragistics103 — clsObjectBinderBase

Behavioral notes

• When TargetTypeIsString is enabled, the setter intentionally does not force ControlBindProperty.Text; the source comments tie that choice to a historical 12:00PM–12:59PM display problem.
• ControlToObject() writes WebDateTimeEditor.Value for string targets and WebDateTimeEditor.Date for non-string targets, so outbound conversion behavior differs from object-to-control mode selection.
• The event handler delegates directly to ControlToObject() without additional state checks.

Constraints and usage notes

• Callers choosing ControlBindProperty.Date or ControlBindProperty.Text for object-to-control transfer must ensure the source property can be converted with CDate or CStr respectively.
• The modern Infragistics.Web.UI.EditorControls date-time editor types used here are not backed by a matching explicit <Reference Include> entry in the scanned project file and therefore depend on unresolved indirect assembly resolution**.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
