Actually, If there is a way to use code behind, that would be great, but I can´t. The only available way is doing right click in my control - Properties - Advanced  and set the screen infomation value. But I need a dynamic setting for a tooltip, pls If anyone have been dealing with this issue, let me know. Thanks.

I've radio buttons and textboxes that show data from a SharePoint List within a repeating table. A column from that list must be a tooltip text setting to my controls (Radiobuttons and Textboxes) How can I do that?, I only set my control's tooltip from Advanced options in my control. Thanks in advance.
