How would you go about creating dynamic tooltips such as the ones found here:
http://freelance.geekinterview.com/143141-issues-with-jquery-cluetip.html
Basically I got a glossary table in my database with definitions that I want to display as a tooltip in my aspx (c#) pages wherever the a keyword will match that of the glossary..
Something basic will do, such as:

You can refer to the following online demos which illustrate with examples different scenarios of displaying RadToolTips. Probably this should help you get started:
RadToolTip
Tooltipify Specific Area
Thanks

The RadToolTip provides functionality which offers dynamic creation of tooltips both on the server and on the client.
1) To create a RadToolTip on the server you should use the standard approach you use to dynamically create controls, e.g :
RadToolTip tooltip = new RadToolTip();
tooltip.TargetControlID = myTargetControlID;
//set different properties here
this.form1.Controls.add(tooltip);
2) To create a tooltip on the client you should use the RadToolTipManager's client API and its createToolTip() method which demonstrated in the demo below:
http://demos.telerik.com/aspnet-ajax/tooltip/examples/radtooltipmanagerclientapi/defaultcs.aspx
Since there is ability to create and configure tooltips both on the server and on the client and also to configure them, we believe that this is teh basic needed functionality a control should offer as a built-in functionality. If you expect another built-in functionality, please provide detailed explanations and in case we fpund it useful in enough scenarios and basic enough, we can consider it as a feature request and we can implement it.

As far as I understand your scenario is too specific to implement it as an embedded functionality. Furthermore you are the first one who has such a request for a feature. The controls offer a very rich API which provides teh ability to implement a lot of particular scenarios and we do not intend to implement so specific functionality if we do not have a lot of customers requests.
Please, use the API of the control to achieve what you need and in case you experience problems, do not hesitate to contact us again!

I am trying to create tooltip dynamically, but I failed an exception was thrown
Script control 'TT_1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
here is my code maybe i am wrong:
Telerik.Web.UI.RadToolTip TT =
new Telerik.Web.UI.RadToolTip();
TT.Width = 240;
TT.Height = 130;
TT.OffsetX = 5;
TT.Style.Add(
"background", "url(../../App_Themes/Theme_1280/Images/tooltip.jpg) no-repeat");
TT.TargetControlID =
"cell_1" ;
TT.Position = Telerik.Web.UI.ToolTipPosition.MiddleRight;
TT.HideEvent = Telerik.Web.UI.ToolTipHideEvent.LeaveTargetAndToolTip;
TT.ID =
"TT_1" ;
TT.Controls.Add(table);
Cell.Controls.Add(TT);
greetings

The only thing I can assume without having your code is that you have missed to declare a ScriptManager before teh tooltip is added to the page. If so, please note that script controls should be registered in the ScriptManager and this is the most probable reason for this error. Another option is that you are adding the tooltip in some event which is not suitable considering the page lifecycle but I cannot tell you the exact reason until I am able to see what is actually goind on.
This being said, if the problem persists, please provide code on base of which a fully runnable reproduction page could be created and I will do my best to help.
