This client-side event is fired when a RadListView item is about to be dropped after dragging.

Fired by	RadListView
Arguments	dataKeyValues - Array of the item key fields set through the ClientDataKeyNames property of the RadListView control, itemIndex - the index of the dragged item, destinationElement - the destination HTML element, domEvent - dom event
Can be canceled	Yes

Example:

ASP.NET

<telerik:RadListView ID="RadListView1" runat="server" ClientDataKeyNames="Title, Artist">
    <ClientSettings AllowItemsDragDrop="true">
        <ClientEvents OnItemDropping="ItemDropping" />
    </ClientSettings>
</telerik:RadListView>

JavaScript

function ItemDropping(sender, eventArgs) {
    var dest = eventArgs.get_destinationElement();
    if (!dest | | !dest.id | | dest.id.indexOf("DestinationPanel") < 0) {
        eventArgs.set_cancel(true);
    }
}

To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel() or set_cancel().

The get_dataKeyValues() method is supported only with server data binding. If you are using client binding, see the Item drag and drop with client data binding KB article.
