Hi,

{
   public Form1()
   {
      InitializeComponent();
      this.FormClosing +=new FormClosingEventHandler(Form1_FormClosing);
   }

   private void Form1_FormClosing(object sender, FormClosingEventArgs e)
   {
      if (e.CloseReason != CloseReason.UserClosing)
         return;

      if (String.IsNullOrEmpty(textBox1.Text))
      {
         if (MessageBox.Show("Are you sure you want to close the form?", "Warning", MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.No)
            e.Cancel = true;
      }
      else
      {
         if (MessageBox.Show("You want to save data or not?", "Warning", MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.Yes)
         {
