[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Namespace:  Microsoft.WindowsCE.Forms
Assembly:  Microsoft.WindowsCE.Forms (in Microsoft.WindowsCE.Forms.dll)

Syntax

'Declaration
Public Class DocumentList _
    Inherits Control
'Usage
Dim instance As DocumentList
public class DocumentList : Control
public ref class DocumentList : public Control
type DocumentList =  
    class
        inherit Control
    end

Remarks

A DocumentList control provides a managed implementation of the native Windows CE DocList control, the control that is visible, for example, when you start Microsoft® Pocket Word and Microsoft® Pocket Excel. This control provides the following functionality:

  • Select, delete, copy, move, and rename files and folders.

  • Sort by a file name, date, or size.

  • E-mail files.

  • Send files by infrared to another device.

A DocumentList is a control rather then an entire dialog like such as FileDialog. Using a DocumentList control allows you include custom menus or other controls in your files selection UI.

A DocumentList should have the same width as the form on which it is placed. The length can be as long as needed.

A DocumentList only displays the files of a selected folder in the My Documents hierarchy.
