Hi All,

I need to display multiple items on one line of text in a combo box.
Such as

C#

"One,a,b
 Two,a,b
 Three,a,b"

While the comboBox.Items.Add() only lets one object, I was hoping the AddRange() control
would it, but it doesn't seem to or is my GoogleFu weak this morning as I have done the following:

C#

cboDUTComPort.Items.AddRange(new[] {nameArray[index],"Narf"});

but this Splits onto a new line each time. giving

C#

nameArray[0]
"Narf"

rather than the hoped for

C#

nameArray[0], "Narf"

I am close but...

Have you tried:

C#

cboDUTComPort.Items.Add(string.Join(",", new [] {nameArray[index], "Narf"}));

The other solution is to create a class to hold the multiple values and override ToString in that: the combo box item is then the class instance, which means you don't have to parse or split anything later when you want to use it.

public class MyClass
{
public string Name { get; set; }
public int Baud { get; set; }
public int BitsPerChar { get; set; }
public override string ToString()
{
return string.Format("{0}, {1}, {2}", Name, Baud, BitsPerChar);
}
}
...
myComboBox.Items.Add(new MyClass() { Name = "COM1", Baud = 9600, BitsPerChar = 8 });
...
MyClass mc = (MyClass) myComboBox.Items[0];
Console.WriteLine(mc.Name);
