Hi Deva, 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 Treeview_Node__Related_data { 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) { treeView1.Nodes.Add("Please select any table"); treeView1.Nodes.Add("student"); treeView1.Nodes.Add("employee"); treeView1.Nodes.Add("product"); } private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { OleDbConnection con = new OleDbConnection(ConnectionString); if (treeView1.SelectedNode.Text == "Please select any table") { } else if (treeView1.SelectedNode.Text == "student") { con.Open(); str = "select * from student"; com = new OleDbCommand(str, con); oledbda = new OleDbDataAdapter(com); ds = new DataSet(); oledbda.Fill(ds, "student"); dataGridView1.DataMember = "student"; dataGridView1.DataSource = ds; con.Close(); dataGridView1.Visible = true; dataGridView2.Visible = false; dataGridView3.Visible = false; } else if (treeView1.SelectedNode.Text == "employee") { con.Open(); str = "select * from employee"; com = new OleDbCommand(str, con); oledbda = new OleDbDataAdapter(com); ds = new DataSet(); oledbda.Fill(ds, "employee"); dataGridView2.DataMember = "employee"; dataGridView2.DataSource = ds; con.Close(); dataGridView1.Visible = false; dataGridView2.Visible = true; dataGridView3.Visible = false; } else if (treeView1.SelectedNode.Text == "product") { con.Open(); str = "select * from product"; com = new OleDbCommand(str, con); oledbda = new OleDbDataAdapter(com); ds = new DataSet(); oledbda.Fill(ds, "product"); dataGridView3.DataMember = "product"; dataGridView3.DataSource = ds; con.Close(); dataGridView1.Visible = false; dataGridView2.Visible = false; dataGridView3.Visible = true; } } } } Thanks If this post helps you mark it as answer
