how to add a control to a "property box"

My PropertyGrid displays many string variables which are paths to files and folders,

I wouldn't want someone to edit them manually in textBox

is it possible to (set the read-only property field and) add a button "..." exactly the same as it appears in the Collection type

hello Gokul,

thank you so much for your help!

meanwhile I managed to read about custom editor and solved that by creating my BrowseFolderEditor,

your solution seems more elegant to me :)

my code:

public class BrowseFolderEditor : ITypeEditor
private Grid browseGrid;
private TextBox browseTextBox;
private Button browseButton;

public void Attach(PropertyViewItem property, PropertyItem info)
var binding = new Binding("Value")
Mode = BindingMode.TwoWay,
Source = info,
ValidatesOnExceptions = true,
ValidatesOnDataErrors = true

BindingOperations.SetBinding(browseTextBox, TextBox.TextProperty, binding);

public object Create(PropertyInfo propertyInfo)
browseGrid = new Grid();

var gridCol1 = new ColumnDefinition
Width = new GridLength(1, GridUnitType.Star)

var gridCol2 = new ColumnDefinition
Width = new GridLength(50, GridUnitType.Pixel)

browseTextBox = new TextBox()
IsReadOnly = true,
BorderThickness = new Thickness(0),
VerticalContentAlignment = VerticalAlignment.Center,
Grid.SetColumn(browseTextBox, 0);

browseButton = new Button
Content = "...",
browseButton.Click += BrowseFolder;
Grid.SetColumn(browseButton, 1);


return browseGrid;

public void Detach(PropertyViewItem property)
browseGrid = null;
browseTextBox = null;
browseButton = null;

private void BrowseFolder(object sender, RoutedEventArgs e)
using (var fbd = new FolderBrowserDialog())
var result = fbd.ShowDialog();
if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath))
browseTextBox.Text = fbd.SelectedPath;
browseTextBox.Focus(); //focus to refresh the value
