SAIFAJAXControlAncestor

SAIFAJAXControlAncestor is the shared root class for the AJAX display-control families in this library (auto-binding editors, hover-help/hover-panel controls, and grid-customization controls). BindingManager is a documented exception: it inherits directly from System.Web.UI.WebControls.CompositeControl rather than from this class. SAIFAJAXControlAncestor resolves the page-level model object once per control instance (caching it in RootObject) and provides a browser-detection helper, freeing every derived control from having to repeat model-lookup boilerplate.

Purpose

• Resolves and caches the page's model object (RootObject, via BindingUtility.GetObjectValue(Page, "Model")) so derived controls can read model data without repeating the lookup.
• Provides IsFirefox, a simple user-agent check used by derived controls to branch client-side rendering behavior for Firefox.

Context

• Namespace: SAIF.Presentation.Web.Controls.V2.AJAX
• Assembly/package: SAIF.Presentation.Web.Controls.AJAX.Infragistics103

Public members

Member	Signature	Purpose
RootObject	Protected ReadOnly Property RootObject() As Object	Lazily resolves and caches the page's "Model" object for use by derived controls
IsFirefox	Protected ReadOnly Property IsFirefox() As Boolean	Indicates whether the requesting browser identifies itself as Firefox

Inherited public members

Members in this section are inherited from System.Web.UI.WebControls.CompositeControl in the .NET Framework Base Class Library. They are available on this type through inheritance.

Member	Signature	Purpose	Origin
ID	Property ID As String	The programmatic identifier assigned to this control instance	System.Web.dll — System.Web.UI.Control
Visible	Property Visible As Boolean	Controls whether this control renders on the page	System.Web.dll — System.Web.UI.Control
CssClass	Property CssClass As String	The CSS class rendered on the control's container element	System.Web.dll — System.Web.UI.WebControls.WebControl
CreateChildControls	Overridable Sub CreateChildControls()	Builds this composite control's child control tree; overridden by every derived control in this library	System.Web.dll — System.Web.UI.WebControls.CompositeControl
RenderContents	Overridable Sub RenderContents(writer As HtmlTextWriter)	Renders this composite control's markup to the response stream	System.Web.dll — System.Web.UI.WebControls.CompositeControl
DataBind	Overridable Sub DataBind()	Runs the standard ASP.NET data-binding lifecycle for this control	System.Web.dll — System.Web.UI.Control

Behavioral notes

• A large commented-out ScriptManager helper region exists in this class (AJAX-enablement helpers for classic ASP.NET AJAX) but is not part of the active implementation.

Constraints and usage notes

• MustInherit: this class cannot be instantiated directly; the AJAX display-control families in this library derive from it either directly or via AutoBindControlAncestor. BindingManager is excluded from this hierarchy — it derives directly from CompositeControl.
