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?
