Function to retrieve date parameters and either show error message or call Binding function:

private void LoadData() {
  try {
    DateTime date1 = Convert.ToDateTime(TextBox1.Text);
    DateTime date2 = Convert.ToDateTime(textbox2.Text);
    if (date1 >= date2) {
      label1.Text = "Invalid Dates";
    } else {
      BindDataInGridview(date1, date2);
    }
  } Catch (Exception ex) {
    // log and report exception
  } 
}

Function to bind the data:

private void BindDataInGridview(DateTime date1, DateTime date2) {
  // Logic to retrieve your data based on date parameters and bind it to the GridView
}
