clsWebDatePickerBinder

This binder connects the modern Infragistics Infragistics.Web.UI.EditorControls.WebDatePicker control family to SAIF business-object properties, acting as the newer-editor counterpart to the classic date-entry binders. It keeps the picker on the standard base-class validation path, can treat the target property as either a Date value or a string-backed text field, and optionally writes changes back immediately when the picker raises ValueChanged.

Purpose

  • Bind a modern Infragistics date picker to a business-object property through the common manager/binder workflow.
  • Support both date-valued and string-valued targets through the TargetTypeIsString switch.
  • Reuse inherited validation/error gathering while specializing date-picker value transfer.

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 Switches reverse binding between saving picker text as a string and saving the picker value as a date/object value.
BindProperty Property BindProperty As String Names the object property synchronized with the picker.
BindSource Property BindSource As Object Supplies the bound object and the validation target used by inherited error lookup.
WebDatePicker Property WebDatePicker As WebDatePicker Attaches the picker control instance and registers it for inherited formatting/validation operations.
Init() Overrides Sub Init() Wires ValueChanged when immediate control-to-object synchronization is enabled.
ObjectToControl() Overrides Function ObjectToControl() As Boolean Pushes the current object value into the picker's Value property.
New() Sub New() Defaults the binder to ControlBindProperty.Value for date-value binding.

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

  • Setting TargetTypeIsString to True also changes the control-bind property to Text, aligning string targets with the picker's textual representation.
  • ControlToObject() writes WebDatePicker.Text when targeting strings and WebDatePicker.Value otherwise.
  • The value-changed event handler does no extra validation work of its own; it simply delegates to ControlToObject().

Constraints and usage notes

  • Object-to-control transfer always writes the picker Value, so callers relying on custom text formatting still depend on the control's own formatting behavior.
  • This binder targets the modern WebDatePicker editor family rather than the classic Infragistics date chooser controls.
