Establish banner defaults

Establish the environment-driven defaults that the render step depends on. Called from OnInit when the BannerControl is not in design mode.

Field Value
Operation ID OP-V2-002
Trigger Called from OnInit when the BannerControl is not in design mode.
Inputs AppGlobal.EnvironmentService.IsClientExternal, the current HttpContext, the template source directory.
Outputs Internal/insider flag, default link visibility flags, resolved banner path, LoggingIn flag.
Primary components BannerControl.SetBannerControlDefaults
Entry point SAIF.Presentation.Web.Controls.V2/Banner.vb

Steps

  1. Read AppGlobal.EnvironmentService.IsClientExternal and set the internal ("insider") flag to its negation. (BR-V2-015)

  2. Origin: AppGlobal.EnvironmentService is imported from the SAIF.Framework.Security namespace; its owning assembly could not be confirmed from this repository.**

  3. Default feedback, banner and logout visibility to "visible only for external clients". (BR-V2-016)
  4. If an HttpContext exists, map /RESOURCES/SITEBANNER.XML to a physical path; if the file does not exist, clear the path so rendering is skipped. (BR-V2-017, BR-V2-003)
  5. Derive the current application name from the last segment of the mapped template source directory (upper-cased) and set LoggingIn when it equals ONLINELOGIN. (BR-V2-018)

Failure and edge-case behavior

  • No exceptional failure handling beyond the branches described in Steps was found in the analysis findings.*

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.
