RE: Update data in TextChanged event show message when retrieve data or show data

What I usually do in this situation is create a Boolean "flag" that is a protected variable in the class. In your case I'll call this variable "bLoading" and assume it's set to false in its declaration. I would then change your code to something like this:

CODE

private void Driver_Load(object sender, EventArgs e)
{
  bLoading = true;
  string constr = "Data Source=" + value1 + ";Initial Catalog=" + value2 + ";User ID=" + value3 + ";Password=" + value4 + "";
  con = new SqlConnection(constr);
  string comdstr = "select * from Driver";
  da = new SqlDataAdapter(comdstr, constr);
  ds = new DataSet();
  da.Fill(ds, "Driver");
  dt = new DataTable();
  dt = ds.Tables["Driver"];
  totalrecord = dt.Rows.Count;
  if (ds != null)
  {
    dt = ds.Tables[0];
    currrecord = 0;
  }
  fillcontrol();
  bLoading = false;
}
 
private void textBox2_TextChanged(object sender, EventArgs e)
{
  if (!bLoading)
  {
    FleetManagment.Fleet fleet1 = new FleetManagment.Fleet();
    int a = fleet1.UpdateDriver("Data Source=" + value1 + ";Initial Catalog=" + value2 + ";User ID=" + value3 + ";Password=" + value4 + "", Convert.ToInt32(textBox1.Text), textBox2.Text, textBox3.Text, textBox4.Text);
    if (a>0)
    {
      message box.show("record successfully updated");
    }
  }
}
