ToolTipManager appears to be malfunctioning ONLY with Telerik controls.  If I add a another control such as a label to the controls collection and set the tooltip on the control, it works as it always has in the past.  The behaivor is that the standard tooltip is displayed, and the radtooltip renders a blank message.  Attached is a picture of the issue.  The tooltipmanager is displaying over the correct combobox, but not displaying the tooltip text.

I added a standard radtooltip control to the page and set it's target to the same radcombobox control, and it works as expected.   I can reproduce with multiple rad controls.

I'm using 2010.1.415.35

Hi Fred,

The behavior you describe most probably comes from the fact that the RadComboBox as all RadControls is complex HTML and it is formed by different standard HTML elements. Thus you should specify the exact element  which should be tooltipified because otherwise you will actually tooltipify another element which I assume is the case with you.

Please, share your code - both the combo and the tooltip manager and how you have tooltipified the combo here and I will examine it and let you know what is the exact reason for the issue. Provide also more details about the exact desired result and I will do my best to provide a solution for you.


Kind regards,
