Folderbrowserdialog Unmasked: Everything You Wanted to Know About the Folder Browser Component From .net Framework

Original Article :http://www.ssware.com/articles/folderbrowserdialog-unmasked-everything-you-wanted-to-know-about-the-folder-browser-component-from-dotnet-framework.htm

Introduction

The FolderBrowserDialog, available as part of the .Net framework, provides a folder browser component for your C# and VB.Net applications. The UI consists of a modal dialog which contains a tree control displaying all the files and folders on the system. The user can then browse and select a folder from the tree. The full path of the selected folder is then returned.

Basic Usage

To display a folder explorer UI to the user, a FolderBrowserDialog instance is created and the ShowDialog method is called. This shows the modal dialog containing the folder browser control (tree) and an OK and Cancel button. If the user selects a folder and clicks the OK button, the ShowDialog method returns DialogResult.OK and the SelectedPath property contains the full path of the selected folder. If the user clicks the Cancel button, the ShowDialog method returns DialogResult.Cancel.

Advanced Usage

The FolderBrowserDialog has some additional features such as limiting the view of the file system that is displayed to the user, pre-selecting a folder when the dialog is first displayed and displaying a button to allow the user to create a new folder.

The RootFolder property can be set to the full path of the folder which is to be displayed as the root of the tree control of the folder browser component. For example, if this property is set to Environment.SpecialFolder.Personal, only folders from the 'My Documents' are displayed in the tree, so the user can only select 'My Documents' or its sub-folders.

Prior to displaying the folder browser control, the SelectedPath property can be set to the full path of a folder causing that folder to be pre-selected in the folder browser tree. For example, when this property is set to "c:", the node corresponding to the c: drive is pre-selected in the tree when the dialog is first displayed.

If the ShowNewFolderButton property is set to true, then, in addition to the folder browser tree control, and the OK and Cancel buttons, the folder browser dialog also displays an additional 'New Folder' button which when clicked, creates a new folder under the currently selected folder.

Limitations

While the folder browser component is a handy way to allow the users to browse and select folders, it suffers from many limitations, some of them preventing the component from being of practical use in applications.

Modal Functionality

The folder browser component of the most obvious drawback is that it is displayed in the form of a modal dialog user interface. Displayed, it will prevent the rest of the application until the user selects a folder. As long as the dialog box is displayed, there is no input (keyboard or mouse click) In addition to occur in the dialog box. The user must input may appear before the caller identification or the Cancel button.

This is a very annoying and limited FolderBrowserDialog function. Users are likely to be irritated, and tired when they interact with a modal dialog box each time they want to explore and select a folder. A non-modal user interface controls can be the application itself is a form or dialog box, which is a more user-friendly display of the same user-friendly way.

No Virtual (Non-file system) folders

The FolderBrowserDialog does not allow the user to select virtual (Non-file system) folders such as the Control Panel or My Computer. It only allows the user to select a file system path such as "c:" or "c:windows".

No Files

The component does not allow the user to select files. This is a major drawback since there are many circumstances where the user may need to select a file while still using the tree UI to browse to that file.

Limited Choice of RootFolder

The root folder of the folder browser control can be only set to one of the 'special folders' defined by Windows such as the 'My Documents' or 'My Computer'. This is a major limitation since this means you cannot set the root folder to a path such as the "d:" drive.

No Check Boxes

The folder explorer tree in the FolderBrowserDialog cannot show check boxes next to nodes. Ability to show multi-state check boxes can be a very handle feature for such a control.

No Filtering

The FolderBrowserDialog has no support for filtering. For example, it is not possible to display only network folders or only shared folders or only folders starting with the string "Documents" or files having a particular extension.

No Custom Controls

When using FolderBrowserDialog, you are only limited to the actual folder tree control manager to identify, cancel, and the New Folder button and description tags. This is a can not add custom control dialog box. This will be useful, in many cases, such as when you want to display thumbnails / preview of the selected file / folder, or any other relevant information.

No Appearance Control

The appearance of the FolderBrowserDialog and its constituent controls cannot be changed. Neither can attributes of individual folders show in the folder explorer control be changed. For example, it is not possible to change the background color of the tree control or to set the font and color of individual nodes/folders in the tree.

No Custom items

The FolderBrowserDialog cannot display external/custom items in the folder explorer tree. For example, it may be necessary to display items from an FTP location in addition to the file system items. This is not possible with the FolderBrowserDialog.

No Lockdown

The FolderBrowserDialog operations can freely Folder. The user can rename the folder, go drag

Beyond The FolderBrowserDialog : The FolderView Control

The Folder View Control brings a Windows Explorer-like folder browser component to your applications complete with AutoUpdate, dragdrop, icons, context menus, non-filesystem items, default key-handling, info tips and rename. It features powerful behavior control and customization functionality takes it miles ahead of Windows Explorer by adding features like filtering, checkboxes, custom items, more than one root node, dragdrop control and customization of default context menus, display names, icons and more tips.

The FolderView control is a UI control which can be dropped right inside your own forms and dialogs. A non-modal file & folder browsing/selection experience right inside your own dialogs and forms is something that users will appreciate and find intuitive and simple.

Additionally, FolderView overcomes all the limitations of the FolderBrowserDialog and provides far greater and advanced features and functionality than the FolderBrowserDialog. The following table is a quick comparison of the FolderView Control with the FolderBrowserDialog.
