DataSet ds;
string str;

public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
comboBox1.Text="Select any name";
OleDbConnection con = new OleDbConnection(ConnectionString);
con.Open();
str = "select * from student";
com = new OleDbCommand(str, con);
OleDbDataReader reader = com.ExecuteReader();
while (reader.Read())
{
comboBox1.Items.Add(reader["sname"].ToString());
}
reader.Close();
con.Close();
}

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection(ConnectionString);
con.Open();
str = "select * from student where sname='" + comboBox1.Text.Trim() + "'";
com = new OleDbCommand(str, con);
oledbda = new OleDbDataAdapter(com);
ds = new DataSet();
oledbda.Fill(ds, "student");
