clsWebMaskEditBinder

This binder adapts the classic Infragistics v10.3 WebMaskEdit control for standard masked-entry scenarios, letting the binding manager choose whether the control contributes text, raw text, or typed values back to a business object. It is the non-SAIF legacy InfragisticsClassicControls mask-edit implementation, parallel to but distinct from the SAIF-specific counterpart.

Purpose

• Synchronize a classic WebMaskEdit control with a bound property using the control surface selected by ControlBindProperty.
• Convert edited mask values back into string, integer, decimal, or date targets according to MaskEditTargetType.
• Optionally react to ValueChange so edits are persisted immediately when UseEvents is enabled.

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
MaskEditTargetType	Property MaskEditTargetType() As ObjectDataType	Declares which target data type the binder should produce when pulling values out of the control.
BindProperty	Property BindProperty() As String	Names the business-object property that receives and supplies the masked value.
BindSource	Property BindSource() As Object	Supplies the business object being edited and the validation source used by inherited error logic.
MaskedEdit	Property MaskedEdit() As WebMaskEdit	Attaches the classic mask-edit control instance and registers it with the base binder infrastructure.
Init()	Overrides Sub Init()	Hooks ValueChange for control-to-object and two-way bindings when event-driven synchronization is enabled.
ObjectToControl()	Overrides Function ObjectToControl() As Boolean	Pushes the bound property into the control's Text, Value, or RawText member according to ControlBindProperty.
New()	Sub New()	Defaults the control-side projection to ControlBindProperty.Text.

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

• ObjectToControl() branches across Text, Value, and RawText, so caller configuration determines which control member is authoritative during display updates.
• ControlToObject() converts control content according to MaskEditTargetType, including underscore-stripping decimal parsing and typed conversions for date and integer targets.
• String targets are written with SetObjectValueAsString, using the trimmed control text rather than the raw underlying value.

Constraints and usage notes

• Choose MaskEditTargetType to match the target property type; the binder uses direct VB conversions such as CDate, CDec, and CInt.
• m_PadLength, m_PadCharacter, and m_PadDirection are declared but not used by binder-local logic; padding behavior comes from inherited base-class services instead.
• Validation formatting and error collection come from inherited clsObjectBinderBase behavior rather than mask-specific logic.
