It seems this thread is very similar to your previous one on the same subject: http://www.telerik.com/community/forums/aspnet-ajax/tooltip/getting-two-tooltips.aspx
. You have not answered any of my questions there, so I would ask that you try my suggestions and let me know what the result is. In case you are using AJAX you can also try moving the RadToolTipManager out of any update panels or AJAX settings to avoid disposing it. You should also make sure it is the only tooltip manager on the page with AutoTooltipify set to true.
What I see in this screenshot is some strange behavior and I cannot find a reason for it in the code snippet you have pasted. It seems to work fine on my end (you can find attached my test page and a video from my experiment). Note that when AutoTooltipify is enabled setting the text manually in the tooltip is not needed. In case comparing them with your actual setup does not help, nor do my ideas from the other thread, I advise that you open a support ticket and send me a simple, runnable project
that shows the problem so I can debug it.
