Communication between parent page and NavigateUrl's page

[Julien]

Hi,

Since i don't really know what is possible, i'll explain my goal :
I have a page which contains a radwindow, and this radwindow contains a form with informations to fill.
In that form i have a hidden field which is empty if no inputs has changed, and filled if any of the inputs has changed.
I'd like that on the close button's click of the radwindow, a test is performed against the hidden field to see if i have to display a javascript confirm like "changes have been made, are you sure you want to close?".

So, how can i proceed to reach the value of the hidden field in the navigate url's page, so i can display the confirm or not?

Or maybe if you have a different solution, i'd like to read it

Thanks and sorry for my english (am i understandable enough?)

Hello Julien,

The OnClientBeforeClose event is handled in the main page, so this is where the confirmation logic must reside. In order to check the hidden filed you need to access the RadWindow's iframe first and call a function that will return the value of the hidden field. The approach for calling such a function is explained in this help article: http://www.telerik.com/help/aspnet-ajax/window-programming-calling-functions.html.
