RE: Binding Windows Form controls to a class as a data source

Setting the binding through the GUI is not currently supported but you can set this up programmatically:

Here is a simple example that binds the Text property of a textbox control to a string property.

     $set ilusing"System.Windows.Forms"
      class-id testwinform.Form1 is partial
                inherits type System.Windows.Forms.Form.
      working-storage section.
      01 mystring   string  value "TEST" property.
      method-id NEW.
      procedure division.

          invoke self::InitializeComponent
          goback.

      end method.

      method-id button1_Click final private.
      procedure division using by value sender as object e as type System.EventArgs.
          invoke textBox1::DataBindings::Add(new type Binding("Text", self, "mystring"))
      end method.
      end class.
