Hi haripriyamca05 and welcome to DaniWeb :)

Please note that there is an ASP.NET forum here at DaniWeb where you can ask ASP.NET questions.

That said, all you need to do in your popup form is listen to the form Closing event, and read the TextBox.Text properties for each text box in your form.

Example:

this.Closing += new EventHandler(form_Closing);

private void form_Closing(object sender, CancelEventArgs e)
{
   string aString = myTextBox.Text;
   // do something with aString here...

   string anotherString = myOtherTextBox.Text;
   // do something with anotherString here...

   // and so on...
}
