I have a web page and a modal dialog page. On clicking the save button in the show modal dialog. closes the window and returns a value. Now when the
control reaches the JavaScript function of the parent window . I wnt to perform some database operation on the basis of this returned ID.

I am using the following approach to utilize this returned value.

  1. Keeping it in the hidden field and populating the returned value in hidden control.
  2. keeping a hidden button in the parent window, performing the click event when control comes back to JavaScript function of the parent page. Thus in the server side button handler get the value from hidden field and perform database operation on the basis of returned value.

Is this approach fine. Or I can get rid of hidden field

    That’s not terribly bad provided the ID returned is not sensitive information that someone can use to modify a record that doesn’t belong to him. One can perfectly manipulate this ID on the client side for any other ID and have your logic update a different record from what you intended.

    If all you are doing is calling a server side method passing this ID; why don’t you do the whole update from the pop-window itself (at that point you already know the ID)?

    If the parent window (page) is meant to be updated; you can just perform a normal refresh of the page (ie. use window.location to redirect the user to the same page so he can see the update or use Response.Redirect to the same page.)
