Hello Swati,

To understand your requirement I have create a sample of UltraTabControl and created two tabs (open /close).

And to have a tooltip to these tabs I set ‘ToolTipText’ option to each tabs like this (you can also set it through design of the control)

ultraTab1.Text = "Add";
ultraTab1.ToolTipText = "This is Tab1";
           
ultraTab2.Text = "Close";
ultraTab2.ToolTipText = "This is tab2";

Now when I run the sample I can see a tooltip to each tabs.

Please also find the attached screen short of the running sample for your reference.

If this is not what you are looking for please provide a sample application or an image of your sample to to have a clear understanding of the requirement.

Let me know if you need further assistance.
