I no wanna show Tooltip for "Corpo Docente", only for subitens ( nu_media_ponderada_Q1,nu_media_ponderada_Q2,nu_media_ponderada_Q3)

Hello Adler,

Just set the HeaderTooltip for the columns themselves:

<telerik:GridBoundColumn ... HeaderTooltip="Description 1">

Hope this helps. Please give it a try and let me know if it works for you.
