I'm trying to get information from one list box to populate another list box.  I'm doing a drag and drop from a list box called available to a list box called selected.  After this has been done I would like to populate another list box called selected2 based on what was in the list box called selected.  I'm able of course to get the drap and drop to work but how do you get the id's from the selected list box.

Thanks,
Mike

Hello Michael,

Please, refer to the Drag-and-drop demo. You can handle OnDropped for the second ListBox and loop through all its items. I recommend you use the Value property instead of the ID property since the latter is reserved for internal use. Here is a code sample:
protected void RadListBox_Dropped(object sender, RadListBoxDroppedEventArgs e)
        {
            if (TextBox1.ClientID == e.HtmlElementID)
            {
                TextBox1.Text = String.Empty;
                foreach (RadListBoxItem item in e.SourceDragItems)
                {
                    TextBox1.Text += item.Text + ", \n";
                }
                if (TextBox1.Text.Length > 0)
                    TextBox1.Text = TextBox1.Text.TrimEnd(new char[] { ',', ' ', '\n' });
            }
            foreach (RadListBoxItem item in RadListBox2.Items)
            
                //item.Value
            }
        }



Kind regards,

Thanks for the help.  I ended up using the radlistbox_transferred event.
