drag and drop between different Rad Windows

[Michael]

I have a RadGrid of inventory items inside a RadWindow.  I have an invoice in a second RadWindow which contains a second RadGrid.  I would like to be able to drag items from the Inventory RadWindow into the Invoice RadWindow.

Does anyone have an example of something like this?

I tried to start with a working example of drag and drop from the Telerik website and put my two grids in different RadWindows.  However, when I start the drag, it won't let me drag the item outside that RadWindow.  It's as if the parent of the items being dragged needs to somehow be parented to the root window and not the RadWindow (that's just a guess).  See the attached image.

Beyond this, I'm not sure what needs to happen on the dropping side.  It would need to get an indication on the other side that these were in fact Inventory items and the list of Items (at least the list of IDs).  Then it could add those to it's list.

Hello Michael,

If your RadWindow instances load separate pages, the window renders an IFRAME that loads the content from your destination URL. You cannot drag HTML DOM elements from IFRAMEs into the parent window or other IFRAMEs.

Is there a way to open a radWindow (without it being an iframe) and then use an ajax request to inject the contents of another url (from the same server) into the new radWindow?

Then, shouldn't I be able to do this sort of dragging and dropping?

This scenario is not supported by RadWindow. You can define both your grids in the two RadWindow content templates on the same ASPX page, though. Thus, your RadGrid instances will live on the same page and you will be able to drag and drop rows in the same DOM tree. For more info, you can refer to the RadWindow - use as a controls container live demo.
