Try this... using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Data.OleDb; namespace Combobox_related_datagridview { public partial class Form1 : Form { string ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["dsn"]; OleDbCommand com; OleDbDataAdapter oledbda; 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"); dataGridView1.DataMember = "student"; dataGridView1.DataSource = ds; con.Close(); } } }
