HoverPanelControl

HoverPanelControl is the headered variant of this library's hover-popup family — it renders a title/header row above an indented content row, unlike the plain HoverPanel. It is composed into HoverHelpControl to give static help popups a visible "Help" title bar.

Purpose

• Renders a two-row popup table (header row + indented content row) anchored to a target control via HoverMenuExtender, only when ContentText is non-empty.
• Provides a configurable content indent (ContentIndentPixels) so the content row visually aligns under the header.

Context

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

DEFAULT_PANEL_WIDTH	Public Const DEFAULT_PANEL_WIDTH As Integer = 300	Default popup panel width in pixels
HeaderText	Property HeaderText() As String	The title text shown in the popup's header row
ContentText	Property ContentText() As String	The content text rendered in the popup's content row; the popup is only rendered when this is non-empty
TargetControlId	Property TargetControlId() As String	The ID of the control that triggers the popup on hover
PopupPosition	Property PopupPosition() As AjaxControlToolkit.HoverMenuPopupPosition	Where the popup appears relative to the target control
ContentIndentPixels	Property ContentIndentPixels() As Integer	Left-indent width, in pixels, applied to the content row relative to the header
PanelWidth	Property PanelWidth() As Integer	The width of the popup panel

Inherited public members

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

Member	Signature	Purpose	Origin
RootObject	Protected ReadOnly Property RootObject() As Object	Lazily resolves and caches the page's "Model" object for use by this control	SAIFAJAXControlAncestor
IsFirefox	Protected ReadOnly Property IsFirefox() As Boolean	Indicates whether the requesting browser identifies itself as Firefox	SAIFAJAXControlAncestor
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
CreateChildControls	Overridable Sub CreateChildControls()	Builds this composite control's child control tree	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

Behavioral notes

• Only renders the header cell's label control if HeaderText is non-empty at CreateChildControls time — an empty header still reserves the header row/cell in the table layout*.

Constraints and usage notes

• TargetControlId must reference a valid control's UniqueID on the same page for the hover popup to trigger correctly.

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.
