Add a ToolTip component to your form Select one of the controls that you want a tool tip for Open the property grid  F4   in the list you will find a property called  ToolTip on toolTip1   or something similar   Set the desired tooltip text on that property  Repeat 2-3 for the other controls Done    The trick here is that the ToolTip control is an extender control  which means that it will extend the set of properties for other controls on the form  Behind the scenes this is achieved by generating code like in Svetlozar s answer  There are other controls working in the same manner  such as the HelpProvider

Drag a tooltip control from the toolbox onto your form  You don t really need to give it any properties other than a name  Then  in the properties of the control you wish to have a tooltip on  look for a new property with the name of the tooltip control you just added  It will by default give you a tooltip when the cursor hovers the control

I did it this way  Just add the event to any control  set the control s tag  and add a conditional to handle the tooltip for the appropriate control tag   private void Info MouseHover object sender  EventArgs e        Control senderObject   sender as Control      string hoveredControl   senderObject Tag ToString            only instantiate a tooltip if the control s tag contains data     if  hoveredControl                      ToolTip info   new ToolTip                       AutomaticDelay   500                     string tooltipMessage   string Empty              add all conditionals here to modify message based on the tag             of the hovered control         if  hoveredControl     save button                         tooltipMessage    This button will save stuff                       info SetToolTip senderObject  tooltipMessage
