Storing objects in Combo and List box

[jay]

I have a structure:


public struct DATA_PAIR
{
public int ID;
public string Value;
public DATA_PAIR(int id, string val)
{
this.ID = id;
this.Value = val;
}
}

I have a combo box and I'm adding items:

....
ArrayList locations = new ArrayList();
locations.Add(new ORCASettings.Common.DATA_PAIR(0, ""));
while (Reader.Read())
{
locations.Add(new ORCASettings.Common.DATA_PAIR((int)Reader[0],
Reader[9].ToString()));
}
cboLocation.ValueMember = "ID" ;
cboLocation.DisplayMember = "Value";
cboLocation.DataSource = locations;
....


....but this doesn't work. ValueMember and DisplayMember don't get affected.
What I get in my combo box is Type of the objects: ClassName+DATA_PAIR.

Thanks,
h

Hi Jay,

You need to define ID and Value as public properties of DATA_PAIR, rather
than public fields - makes for better encapsulation too.

Thanks, it works now!
