Question

Let’s say you have a combobox and a textbox.

The combo box contains a list of items and I would want to bind the textbox “text” property to the current combobox selection.

In WPF this could be done but I’ve not found a way in WinForms.

Is there a way or is WinForms too limited?

Notes:

• I know I could use WPF instead, but the project is already in WinForms and rewriting it is out of the question.
• I’m asking about a combobox and textbox but this could be any other combinations.
• I’m looking for a way to do it from design time it at all possible.

Yes you can bind the text box to the item (Text) selected in a combo box:

   public partial class Form1 : Form {
      Binding binding;

      public Form1() {
         InitializeComponent();

         binding = new Binding("Text", comboBox1, "Text");
         textBox1.DataBindings.Add(binding);
      }
   }
