Public Property AcceptedOperation As DataPackageOperation

Property Value

DataPackageOperation

A value or bitwise combination of values that specifies which operations can be accepted by the target of the drag event.

Examples

In this example, a ListView accepts only text content. In the DragOver event handler, the AcceptedOperation is set to Copy if the DataPackage contains text; otherwise, AcceptedOperation is set to None.

private void TargetListView_DragOver(object sender, DragEventArgs e)
{
    // The list accepts only text.
    e.AcceptedOperation = 
       (e.DataView.Contains(StandardDataFormats.Text)) 
           ? DataPackageOperation.Copy : DataPackageOperation.None;
}

Remarks

This value is set in the DragEnter or DragOver event of the UIElement that is a potential drop target of the drag and drop operation. It notifies the drag source of what operations it can accept, if any, for the DataPackage that is being dragged.

For more info about data operations, see the DataPackageOperation enumeration.
