Small Thing Learned Today

So I needed to show a type name in the textbox today. Like 'DateTime', or 'Integer' etc. I decided to create a binding source and bind to System.Type.Name like this:

this.propertyTypeBindingSource.DataSource = typeof(System.Type);
/* snip */
this.nameTextBox.DataBindings.Add(new System.Windows.Forms.Binding
("Text", this.propertyTypeBindingSource, "Name", true));
/* snip */
Type PropertyType = typeof(DateTime);
this.propertyTypeBindingSource.DataSource = PropertyType;

However, when I try to run the application, I get an exception

"Cannot bind to the property or column Name on the DataSource. Parameter name: dataMember"

So, looks like I'm not allowed to bind directly to System.Type. Maybe I have to do some simple trick ... I create a class

public class StubPropertyType
{ 
 public StubPropertyType(Type type) 
 {
  this.StubPropertyTypeName = type.Name;
 }
 private string _stubPropertyTypeName = string.Empty;
 public string StubPropertyTypeName 
 {
  get { return _stubPropertyTypeName; }  
  set { _stubPropertyTypeName = value; } 
 }
}

and my binding now looks along these lines:

this.propertyStubBindingSource.DataSource = typeof(StubPropertyType);
/* snip */
this.nameTextBox.DataBindings.Add(new System.Windows.Forms.Binding
("Text", this.propertyStubBindingSource, "StubPropertyTypeName", true));
/* snip */
Type PropertyType = typeof(DateTime);
StubPropertyType stub = new StubPropertyType(PropertyType);
this.propertyStubBindingSource.DataSource = stub;

And it works like a charm!
