How to add tooltip to a Windows Form

In Windows Form applications the tooltip functionality is not built into the controls as in HTML objects.

To add tooltip to your controls on Windows Forms

  • Open the Windows Form in the designer
  • Drag the ToolTip control from the Common Controls section of the Toolbox to the form. The ToolTip control will be placed at the bottom margin of the design surface outside of the visible area of the form.
  • A new item appears in the Misc section of the property list of the form controls (buttons, textboxes, etc): ToolTip on toolTip1
  • Enter the text there you want the users to see when they hover above the control.
