As I already explained, you can create and add the tooltip and its content controls in the very same manner you do with other server controls, e.g as shown below:
sender, EventArgs e)
Img = (Image)sender;
RepeaterItem container = (RepeaterItem)Img.NamingContainer;
RadToolTip tip =
tip.RelativeTo = ToolTipRelativeDisplay.Element;
"Dynamically added controls"
tip.Width = Unit.Pixel(200);
tip.Height = Unit.Pixel(200);
tip.TargetControlID = Img.ClientID;
Note, that in the code above I only demonstrated the same I already explained - if you need to change the properties settings, please do so there as shown. Also, I added a LiteralControl - you can add images, labels, etc controls in the same manner.
For your convenience and reference I attach a sample page, let me know how it goes.
