Cancel RadUploadItem Deletion
The RadUpload allows you to cancel the deletion of a RadUploadItem.
In order to take advantage of this feature you will need to handle the RadUploadItem PreviewDelete event.
Add handler for the RadUploadItem PreviewDelete
Example 1: Subscribing to the PreviewDelete event
radUpload.AddHandler(RadUploadItem.PreviewDeleteEvent, new DeleteEventHandler(PreviewDelete));
radUpload.AddHandler(RadUploadItem.PreviewDeleteEvent, New DeleteEventHandler(AddressOf PreviewDelete))
In order to use the Telerik AddHandler overload to attach an event handler for the RadUploadItem.Delete and RadUploadItem.PreviewDelete events, you need to add the following using statement in your file:
using Telerik.Windows;
Handle the PreviewDelete event
Example 2: Handling the PreviewDelete event
void PreviewDelete(object sender, DeleteEventArgs e)
{
e.Handled = true;
}
Private Sub PreviewDelete(ByVal sender As Object, ByVal e As DeleteEventArgs)
e.Handled = True
End Sub
