Version compatibility

The IsDragSource method is not available prior to Windows 10, version 1607. If your app’s 'minimum platform version' setting in Microsoft Visual Studio is less than the 'introduced version' shown in the Requirements block later in this page, you must design and test your app to account for this. For more info, see Version adaptive code.

To avoid exceptions when your app runs on previous versions of Windows 10, do not call this method without first performing a runtime check. This example shows how to use the ApiInformation class to check for the presence of this method before you use it.

if (ApiInformation.IsMethodPresent("Windows.UI.Xaml.Controls.ListViewBase", "IsDragSource"))
{
    bool isDragSource = listView1.IsDragSource();
}
