Gets or sets the application-relative, virtual directory path to the file from which the control is parsed and compiled.
Assembly: System.Web (in System.Web.dll)
When the file that defines a TemplateControl control resides in a directory other than that of the page processing the request, use the property to return the application-relative, virtual path to the TemplateControl.
The AppRelativeTemplateSourceDirectory property is set based on the virtual path that is set in the property.
