namespace MyControlTest

public class MyControl : System.Windows.Forms.Control
{
private System.ComponentModel.Container components;
private string myfield = "";

public MyControl()

InitializeComponent();
}

protected override void Dispose(bool disposing)
{
if (disposing)
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose(disposing);
}

void InitializeComponent ()
{
this.components = new System.ComponentModel.Container ();
}

//PropertyEditor Assign
[
Category("Mycategory"),
Editor(typeof(MyEditor), typeof(UITypeEditor)),
DefaultValue("")

public string MyField
{
get
{
return myfield;
}
set
{
myfield = value;
}
}

}

//Define My property Editor
public class MyEditor : System.Drawing.Design.UITypeEditor
{

public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
{
//Show my dialog
value = "";
return value;
}

public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
