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; namespace Textbox { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void textBox1_Leave(object sender, EventArgs e) { textBox2.Enabled = true; foreach (Control cnt in this.Controls) { if (cnt is TextBox) { if (cnt.Text == "") { textBox2.Enabled = false; } else { textBox2.Enabled = true; } } } } private void textBox1_Enter(object sender, EventArgs e) { textBox2.Enabled = true; textBox2.Text = ""; } } }

on tab change it should not go to the next textbox,rather it should validate with the sqlquery (whether true or false) if true then it should go to the next textbox otherwise it should return and error.

This also should be done on tabcontrol change.

Need to be more clear, on tab change what you want in the textbox, what query you want to validate for the textbox
