I am creating a windows form with TextBox controls. Several of these TextBoxes need to have an associated ToolTip to provide information regarding the TextBox. I understand the display event for the ToolTip is normally triggered by the OnMouseOver event. However, I want to be able to also display the ToolTip on the TextBox GotFocus event. (Some of our users don't use a mouse to navigate through the form.) I haven't been able to find the code that I need to do this, nor have I found any methods or properties that I can use within the ToolTip class. Can anybody help me or direct me to the right source?
