WebFileManager Configuration Options

KB235 Last reviewed 03 August 2015
Configuration variables for WebFileManager.

Overview

WebFileManager has a number of configuration options or variables that may be used to control appearance and functionality. All of these variables have default values and, in some cases, the availability of variables and their values may vary depending on other variables.

By default, WebFileManager operates in a "locked down" mode where it is only possible to view folder and file listings. To enable a specific item of functionality, it has to be manually configured. For example, to enable folder creation, the FolderCreate variable must be enabled.

IIS Permissions

To be able to use any file system actions - like folder creation, file deletion etc - the user account or IIS AppPool used for the host IIS website must have corresponding permissions. Simply enabling functionality within WebFileManager will not enable to corresponding security permission in Windows.

For example, if you enable the FileDelete variable, you must enable File Delete permissions for your IIS website.

Defining Variable Values

WebFileManager configuration values are defined through the Config property of the WebFileManager control. It is recommended that these values are defined at the Load event in the ASP.Net Page Cycle and are redefined even on Postbacks.

The following example shows the simplest configuration

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        ' WebFileManager configuration
        WebFileManager.Config.BaseFolderPath = "~/user"
    End Sub

Configuration Variables

Configuration variables may be categorised as follows:

Group Description
Core Permissions The variables required for WebFileManager to work.
Generic IO Generic FileSystem and IO configuration variables
Files Variable options for managing files including read/write and upload permissions
Folders Variable options for managing folders including write, move and rename permissions
User Interface User Interface (UI) options
3rd Party Integration Generic options for integrating WebFileManager with third party plugins and controls
ckEditor Integration Options for integrating WebFileManager with ckEditor.
