WPF-Callable Folder Browser Source Code [modified]

Mark Salsbery

Here's a simple wrapper around the SHBrowseForFolder() shell function. *EDIT* Updated with more features!

using System;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows;
using System.Windows.Interop;

namespace CommonDialogWrappers
{
/// <summary>
/// Represents a common dialog box (Win32::SHBrowseForFolder()) that allows a user to select a folder.
/// </summary>
public class BrowseForFolderDialog
{
#region Public Properties

    /// <summary>
    /// Gets the current and or final selected folder path.
    /// </summary>
    public string SelectedFolder { get; protected set; }
    /// <summary>
    /// Gets or sets the string that is displayed above the tree view control in the dialog box (must set BEFORE calling ShowDialog()). 
    /// </summary>
    public string Title
    {
        get { return BrowseInfo.lpszTitle; }
        set { BrowseInfo.lpszTitle = value; }
    }
    /// <summary>
    /// Gets or sets the initially selected folder path.
    /// </summary>
    public string InitialFolder { get; set; }
    /// <summary>
    /// Gets or sets the initially selected and expanded folder path.  Overrides SelectedFolder.
    /// </summary>
    public string InitialExpandedFolder { get; set; }
    /// <summary>
    /// Gets or sets the text for the dialog's OK button.
    /// </summary>
    public string OKButtonText { get; set; }
    BROWSEINFOW browseInfo;
    /// <summary>
    /// Provides direct access to the Win32::SHBrowseForFolder() BROWSEINFO structure used to create the dialog in ShowDialog().
    /// </summary>
    public BROWSEINFOW BrowseInfo
    {
        get { return browseInfo; }
        protected set { browseInfo = value; }
    }
    /// <summary>
    /// Provides direct access to the ulFlags field of the Win32::SHBrowseForFolder() structure used to create the dialog in ShowDialog().
    /// </summary>
    public BrowseInfoFlags BrowserDialogFlags
    {
        get { return BrowseInfo.ulFlags; }
        set { BrowseInfo.ulFlags = value; }
    }

    #endregion


    #region Public Constructors

    /// <summary>
    /// Constructs a BrowseForFolderDialog with default BrowseInfoFla

Heh thanks. I think the only comments are the ones copied from SDK headers. I matched the ShowDialog prototypes to Microsoft.Win32.OpenFileDialog's ShowDialog() methods, hence the Nullable<bool> return type.
