Hello,
I am trying to bind the display and value members to a combobox from an arrayList that contains a custon Object.

I made the object "ComboItem" that holds a name and a value.  Each of these are added to the Arraylist.  The datasource line works, but it won't accept the names of the DisplayMember or the ValueMember.

What am I doing wrong?  I've already tried changing the value variable in ComboItem as an int; and changing the case of the names.

thanks,
Sarah


 private void MainForm_Load(object sender, EventArgs e) {      
          IList aList = new ArrayList();
            ComboItem cItemNone = new ComboItem("None", "-1");
       
            aList.Add(cItemNone);

            foreach (DataRow dr in dataSet.Tables["Students"].Rows) {
                ComboItem cItem = new ComboItem(dr[1].ToString(),dr[0].ToString());
                aList.Add(cItem);
            }

            StudentComboBox.DataSource = aList;

            StudentComboBox.DisplayMember = "name";
            StudentComboBox.ValueMember = "value";
   }



 private class ComboItem {
            public string Name;
            public string Value;

            public ComboItem(string name, string value) {
                Name = name;
                Value = value;
            }
        }

Use this class istead of your class

  public class ComboItem
    {
        int _value = 0;
        string _text = string.Empty;

        public int Value
        {
            get { return _value; }
            set { _value = value; }
        }

        public string Text
        {
            get { return _text; }
            set { _text = value; }
        }
       
    }
