Show code and name in combobox picklist

[Andrus]

I need select from list containing product code and name but show only code
in combo textbox.

Tried code below but dropdown list shows only code.
How to display code AND name in selection list ?

using System.Collections.Generic;
using System.Windows.Forms;

class testForm : Form
{
testForm()
{
ComboBox cm = new ComboBox() { DisplayMember = "DisplayMember",
ValueMember = "Code" };
List<ProductprodList = new List<Product>();
prodList.Add(new Product() { Code = "001", Name = "Wine", Cb =
cm });
prodList.Add(new Product() { Code = "002", Name = "Beer", Cb =
cm });
cm.DataSource = prodList;
cm.DataBindings.Add("SelectedValue", prodList, "Code");
Controls.Add(cm);
}

class Product
{
public ComboBox Cb;
public string Code { get; set; }
public string Name { get; set; }

public string DisplayMember
{
get
{
if (Cb.DroppedDown)
return Code + " " + Name;
else
return Code;
}
}
}

static void Main()
{
Application.Run(new testForm());
}
}

You need to override the ToString() for the Product class to display
it the way you want to see it in the combobox.

This is a great learning example, so thanks for posting it. If anyone can
answer my questions, I'd be grateful.

I see that you're creating a combobox in code; my preference would be to
have this in the xaml. What is your reasoning?

When I try to assign to mycombo.DataSource, vs2k8 says comboboxes don't have
DataSource as member. What am I missing?

This is winforms, not wpf.

How to force it to show both code and name ?

using System.Collections.Generic;
using System.Windows.Forms;

class testForm : Form
{
testForm()
{
ComboBox cm = new ComboBox()
{
ValueMember = "Code"
};
Lis<ProductprodList = new List<Product>();
prodList.Add(new Product() { Code = "001", Name = "Wine", Cb =
cm });
prodList.Add(new Product() { Code = "002", Name = "Beer", Cb =
cm });
cm.DataSource = prodList;
cm.DataBindings.Add("SelectedValue", prodList, "Code");
Controls.Add(cm);
}

class Product
{
public string Code { get; set; }
public string Name { get; set; }

public override string ToString()
{
return Code + " " + Name;
}
}
