Hello Gabriel,

I tried this on my end and it is working as expected. You can try the code below and check for differences if any.
aspx:

<telerik:RadToolTip ID="RadToolTip1" Title="RadComboBox" Text="values" TargetControlID="RadComboBox2" Position="TopLeft" RelativeTo="Element" runat="server">
</telerik:RadToolTip>

You can also try setting the OffsetX and OffsetY values as given in the link below.
Positioning

Thanks
Princy.
