    I have two ListBoxes that I am allowing a user to drag items from onto a GridView. Depending on which ListBox they are dragging from, I need to perform different operations.

    So my question is how do I determine which ListBox control the user is dragging an item from at the time of drop?

    Hello Michael Hassinger,

    You could take advantage of the property e.Options.Source which keep track of the source element being dragged (in your case this could be ListBoxItem) and then check which listbox it belongs to. Let me know if you have any questions regarding this scenario.

    Yes, I am able to get to the parent ListBox control name once I create a ListBoxItem and set it to e.Options.Source.

    Thanks!
