    I would like to know the best way to utilise a radwindow for the following scenario.

    in my application im setting a link to allow a user to mark where their location is on google maps. the google map is being loaded in a radwindow, im currently passing the record id and postcode to the map page via a querystring. is this the best way or is there an alternative?

    where im having a problem is i want to include a button whereby the user clicks after moving the marker and this function will close the window and pass the parameters for id, postcode, lat + lng coordinates to the calling page.

    the samples ive found are client side but i need the parameter values server side as i want to update a database record with the coorinates related to the location set by the user.

    i also need a way to deal with the user closing the window via the x in the corner rather than my button. maybe a prompt?

    so the main issue is, once the user clicks the button to close the window how do i get the values in my code-behind module?

    Hello Mark,

    On opening the RadWindow - I am not sure what your scenario exactly is, but using the querystring to pass arguments is one of the quickest ways to command a page that is loaded in an iframe, so if this functionailty is currently working for you I believe you can continue using it.

    Passing values through the code-behind between different pages is a general ASP task that does not depend on the RadWindow. It is up to the developer to create this functionality, yet I can suggest you use either a global class to store the information or a session variable.

    Alternatively, you can get the values on the client via JavaScript (including on the OnClientBeforeClose event, where you can also add a confirmation dialog) and pass them via JavaScript to the parent page. Then you can place the data in a hidden field and perform an AJAX request to get them to the server.

    All the best,
