clsWebNumericEditBinder

clsWebNumericEditBinder binds an Infragistics WebNumericEdit control to a business-object numeric property, selecting the specific typed value property named by NumericControlProperty and handling nullable-decimal blank/NaN semantics.

Purpose

• Write to the specific Infragistics value property named by NumericControlProperty (Text, Value, ValueByte, ValueDecimal, ValueDouble, ValueFloat, ValueInt, ValueLong, ValueShort) (BR-BIND-014).
• Display a Nothing NullableDecimal value as Double.NaN (an empty editor) (BR-BIND-015).
• Store an empty Nullable(Of Decimal) when the editor text is empty, and write the editor's Text verbatim for a String target (BR-BIND-022, BR-BIND-023).

Context

• Namespace: SAIF.Presentation.Web.Binding
• Assembly/package: SAIF.Presentation.Web.Binding.Infragistics111 (ILMerged into SAIF.Presentation.Web.Infragistics111.dll)
• Base class: clsObjectBinderBase

Public members

Member	Signature	Purpose
Init	Public Overrides Sub Init()	Subscribes to ValueChange when UseEvents is True and the bind type calls for write-back (BR-BIND-007, BR-BIND-008). Overrides clsObjectBinderBase.Init.
ObjectToControl	Public Overrides Function ObjectToControl() As Boolean	Branches on the configured target type: writes Double.NaN for a Nothing NullableDecimal value, otherwise writes the specific NumericControlProperty-named property (BR-BIND-014, BR-BIND-015). Overrides clsObjectBinderBase.ObjectToControl.
ControlToObject	Public Overrides Function ControlToObject() As Boolean	Branches on target type: String writes the control's Text; NullableDecimal writes an empty nullable when the control text is empty and ValueDecimal otherwise; every other target writes the NumericControlProperty-named property (BR-BIND-022, BR-BIND-023). Overrides clsObjectBinderBase.ControlToObject.

Inherited public members

Members in this section are inherited from clsObjectBinderBase. They are available on this type through inheritance.

Member	Signature	Purpose	Origin
BindSource	Public Property BindSource() As Object	The business object (or collection) this binder reads and writes. Setting it also sets the binder's validation source unless dual binding overrides it (BR-BIND-002).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
BindProperty	Public Property BindProperty() As String	Name of the property on BindSource this binder gets/sets by reflection.	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
FormControl	Public Property FormControl() As Control	The ASP.NET/Infragistics control instance this binder targets; its UniqueID is the key used by clsObjectBindManager.Binder and Update lookups.	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
BindType	Public Property BindType() As BindTypes	Controls which directions data moves for this binder — ObjectToControl, ControlToObject, TwoWay, or ValidateOnly (BR-BIND-010).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
UseEvents	Public Property UseEvents() As Boolean	Whether this binder subscribes to its control's change event in Init (BR-BIND-007, BR-BIND-008).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
ValidationKey	Friend Overridable ReadOnly Property ValidationKey() As String	Computes the key under which this binder's validation object is registered — the business object's MyGuid for SAIF framework objects (via IsSAIFFrameWorkObject) or its type name otherwise (BR-BIND-004).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
IsSAIFFrameWorkObject	Friend Overridable ReadOnly Property IsSAIFFrameWorkObject() As Boolean	Walks the bind source's runtime base-class chain for the names clsBusinessBase / clsBusinessCollectionBase to decide whether framework-specific keying and validation applies (BR-BIND-061).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
GetObjectValueAsString	Protected Function GetObjectValueAsString() As String	Reads BindProperty from BindSource through TypeDescriptor/PropertyDescriptor and the property's TypeConverter, applying configured padding, for display in simple-value controls (BR-BIND-012, BR-BIND-013).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
SetObjectValueAsString	Protected Sub SetObjectValueAsString(inValue As String)	Writes a string value back onto BindProperty. Computes a padded value for PadTarget.Object but assigns the unpadded value to the property, so object-side padding has no observable effect.*	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
GetErrors	Public Overridable Function GetErrors() As Boolean	Selects the validation property/source for a dual binder (otherwise the bind property/source), casts it to IDataErrorInfo, and reads Item(property) to populate ControlErrors (BR-BIND-031, BR-BIND-032, BR-BIND-033).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
ControlErrors	Public ReadOnly Property ControlErrors() As ArrayList	The list of non-blank, CRLF-split, <BR>-stripped error message fragments harvested for this binder in the current validation pass.	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
SetControlFormat	Public Sub SetControlFormat(inValid As Boolean)	Applies error or valid CSS/color styling to FormControl based on control kind — errorbordercolor/errorbackcolor when invalid (BR-BIND-037, BR-BIND-038), normal/defaultbackcolor when valid, honoring an existing disabledbackcolor class (BR-BIND-039, BR-BIND-040).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase
SetDualBinding	Friend Sub SetDualBinding(inValidationSource As Object, inValidationProperty As String)	Records a validation object/property distinct from the bind object/property, so the control can display one object while validating another (BR-BIND-059).	SAIF.Presentation.Web.Binding.Infragistics111 — clsObjectBinderBase

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. Statements marked with † were retrieved from dependency library documentation via the Legends CLI RAG service. They describe inherited behavior from the indicated origin library and should be verified if the dependency version changes.
