    I'm using dragandrop with multiple elements that pull a ListBoxItem a canvas and I wonder if there is a way of identifying the elements I have in the canvas, I understand that the location coordinates I can do with e . Options.CurrentDragPoint.X.ToString () ,but I can not identify each one of these with a name or identifier

    Help me please

    Hello Xola,

    I am not sure that I fully understand what your concern is. When you add the item in the Canvas, you can set the item's Name property and then, if you want to retrieve it, you can use the Canvas' FindName method.

    TextBlock textBlock = new TextBlock() { Text = "Unmodified" };
    textBlock.Name = "textBlock1";
    canvas1.Children.Add(textBlock);
    TextBlock retrievedTextBlock = canvas1.FindName("textBlock1") as TextBlock;
    retrievedTextBlock.Text = "Modified";

    If this does not answer your question, could you please elaborate a little bit more on what are you trying to achieve and what the actual proble with RadDragAndDropManager is. I'd be glad to further assist you.

    Sincerely yours,
