Passing data from child window

[Santhosh]

Hello

I have a window control to get the customer details from user.   Along with i have search button, to find out existing customer details for editing.  For search, a separate kendo window control is used by showing the list of customer in the grid.  

Here how to pass the customer id from search window to customer window after selecting the particular customer in grid view.  ie, how to get the customer id from child window to parent window.

thanks & regards
