Assembly: System.Web (in System.Web.dll)
The property specifies the path to the page or user control that contains the current control. For example, if the Web page resides at http://www.contoso.com/application/subdirectory, the property returns "application/subdirectory".
To return the application-relative virtual path ("~/subdirectory"), use the AppRelativeTemplateSourceDirectory property.
The following example uses the property twice. The first time it is used in a Control.MapPathSecure method call to obtain the path to the directory in which the control resides. The second time it is in a Directory.GetFiles method call to obtain the list of all the files contained within that directory.
// An HttpException occurs if the server control does not,; // have permissions to read the resulting mapped file. output.Write("The Actual Path of the virtual directory : "+ MapPathSecure(TemplateSourceDirectory)+"<br>"); // Get all the files from the absolute path of 'MyControl'; // using TemplateSourceDirectory which gives the virtual Directory. string  myFiles= Directory.GetFiles(MapPathSecure(TemplateSourceDirectory)); output.Write("The files in this Directory are <br>"); // List all the files. for (int i=0;i<myFiles.Length;i++) output.Write(myFiles[i]+"<br>");
