try it with Dataset

Dataset ds = new Dataset();
DataAdapter dt = new dataAdapter(Com);
dt.fill(ds);

comboBox2.DataSource = ds;
comboBox2.DisplayMember = "MemberName";
comboBox2.ValueMember = "MemID";

C#

//with DataReader
try
{
// opening the connection
connection.Open();
OleDbDataReader dr = command.ExecuteReader();
if (dr.HasRows)
{
// Iterate through the table
while (dr.Read())
{
//adding item to the combobox. you can also use dr[1] to get the country name
comboBox1.Items.Add(dr["CountryName"]);
}
}
}
catch (Exception ex)
{
MessageBox.Show("The following error occured :rn" + ex.ToString());
}
finally
{
// close the connection and DataReader
connection.Close();
dr.Close();
}
}
