How to retrieve object data from combobox?

[hh2424]

//I have the following data bind to a comboBox

public struct DataContainer
{
private string pvrKey, prvValue;

public DataContainer(string parKey , string parValue)
{
this.pvrKey = parKey ; this.prvValue = parValue ;
}

public string getKey { get { return pvrKey; } }
public string getValue { get { return prvValue; } }
}



ArrayList CmbData = new ArrayList ();

while (dr.Read())
{
CmbData.Add (new DataContainer(Convert.ToString(dr.GetValue(dr.GetOrdinal("CustKey&quot)), Convert.ToString(dr.GetValue(dr.GetOrdinal("CustName&quot))));
}

this.cmbAccountName.DataSource = CmbData;
this.cmbAccountName.DisplayMember = "getValue";


// When the user selects an item from the combobox
// How can I retrieve the "Key" value of the object the user selected?
