RadToolTip for ASP.NET AJAX Version Q3 2008 released 11/25/2008 (release history)

TargetControlID property

This example demonstrates three of the most common scenarios when the TargetControlID of the RadToolTip control is useful - the following ones:

1. You have a control, that is a direct child of the form and you want to show a RadToolTip for it.
2. You have a control in an ItemTemplate of a RadGrid column and you want to show a RadToolTip for it.
3. You have a control in a UserControl and you want to show a RadToolTip for it.

In all three scenarios, you just need to set the TargetControlID property of the RadToolTip to the ID of the control, you want to tooltipify.
