FolderBrowserDialog Control

What is Folder Dialog Box Control ?

For browsing and selecting a folder on a computer, a FolderBrowserDialog control is used. A typical FolderBrowserDialog is a control where we can see Windows Explorer-like features to navigate through folders and select a folder.
We often have to prompt users to select a folder in Windows applications we create, most often to save a set of files. The Windows Forms FolderBrowserDialog component allows us to easily accomplish this task.

To choose folders with the FolderBrowserDialog component

• In a procedure, check the FolderBrowserDialog component's DialogResult property to see how the dialog box was closed and get the value of the FolderBrowserDialog component's SelectedPath property.
• If you need to set the top-most folder that will appear within the tree view of the dialog box, set the RootFolder property, which takes a member of the Environment. SpecialFolder enumeration.
• Additionally, we can set the Description property, which specifies the text string that appears at the top of the folder-browser tree view.

 

Example:

In the example below, the FolderBrowserDialog component is used to select a folder, similar to when we create a project in Visual Studio and a folder to be saved in is prompted to select. The name of the folder will then be displayed on the form in a TextBox control. Placing the location in an editable area, such as a TextBox control, is a good idea to allow users to edit their selection in case of error or other problems.

private void btnBrowse_Click(object sender, EventArgs e)
        {
            DialogResult result = folderBrowserDialog1.ShowDialog();
            if(result==DialogResult.OK)
            {
                txtFolder.Text = folderBrowserDialog1.SelectedPath;
            }
        }

 

Complete Code :

using System;
using System.Windows.Forms;

namespace FolderBrowserDialogControl
{
    public partial class frmFolderDialog : Form
    {
        public frmFolderDialog()
        {
            InitializeComponent();
        }

        private void btnBrowse_Click(object sender, EventArgs e)
        {
            DialogResult result = folderBrowserDialog1.ShowDialog();
            if(result==DialogResult.OK)
            {
                txtFolder.Text = folderBrowserDialog1.SelectedPath;
            }
        }
    }
}
